| TERM | DEFINITION |
|---|---|
| ADJUDICATION (WORD LOOKUP) | The process of ruling on the validity of a challenged word, typically by consulting an official word judge, a designated software tool (such as Zyzzyva in Word Judge mode), or a tournament director. |
| AEROLITH | A free web-based flashcard tool for studying Scrabble word lists. See https://aerolith.org/. |
| ALPHAGRAM | A word's letters arranged in alphabetical order (e.g., RETINA → AEINRT). Players study alphagrams to recognize patterns and find words more easily. |
| ANAGRAM | A word or phrase formed by rearranging the letters of another word or set of tiles. |
| ANAMONIC | A short memory phrase used to help remember which letters combine with a stem to form a bingo. See the PDX Scrabble anamonics study page. |
| BACK HOOK | A single letter added to the end of a word to form a new valid word (e.g., FORGE → FORGET). See the hook lists on this site. |
| BINGO (BONUS / SEVEN) | A play that uses all 7 tiles on your rack, earning a 50-point bonus. The word played may be 7 or 8 (or more) letters long — the bonus is for using all 7 rack tiles, regardless of word length. |
| BLANK | A tile with no letter (and no point value) that can represent any letter. Blanks are among the most powerful tiles in the game because they make bingos much easier. See POWER TILES. |
| BLOCKER (BLOCKING MOVE) | A defensive play that closes off scoring opportunities on the board. |
| BLOCKING MOVE | See BLOCKER (BLOCKING MOVE). |
| BLOWOUT | A game won by a large margin (spread). |
| BOARD VISION | The ability to find and evaluate hot spots, bingo lanes, and board geometry quickly. |
| BONUS | See BINGO (BONUS / SEVEN). |
| BONUS SQUARE | A square on a Scrabble board that gives an extra scoring bonus: double-letter, triple-letter, double-word, or triple-word; also called a premium square. |
| BOX-TOP RULES | The rules used by kitchen-table players. |
| BRAILING | Illegally feeling tiles in the bag to identify them by touch — particularly to find blanks, which may have a subtly different texture. Tournament tiles (see TOURNAMENT TILES) are designed to prevent this. Brailing is a serious rules violation. |
| BURN | Using a valuable tile (such as an S or blank) for less than its full scoring potential, usually for strategic reasons. |
| CARDBOX | A physical or software-based spaced-repetition flashcard system for studying Scrabble words. See ZYZZYVA. |
| CASE [LETTER] | The last remaining tile of a specific letter. When only one of a given letter is left unseen — in the bag or on your opponent's rack — it is called "the case [letter]." Knowing the case tile is critical in endgame planning. |
| CENTER STAR (STAR) | The middle square on the board. The first word must cover it, and it counts as a double word score. |
| CHALLENGE | Questioning whether an opponent's word is valid. A correct challenge removes the word; an incorrect challenge may be penalized depending on the rules. See DOUBLE CHALLENGE, SINGLE CHALLENGE, POINT PENALTY CHALLENGE. |
| CHALLENGE WINDOW | The period during which a challenge may be initiated before the next draw or play. |
| CHANGE | See EXCHANGE (CHANGE / "PASSING N"). |
| CLOCK (TIMER) | A chess-style device used to track each player's thinking time. (Only some electronic chess timers are acceptable as they need to keep running when the time goes below zero). |
| CLOCK STOP (STOPPAGE) | See STOP (STOPPAGE). |
| CLOSED BOARD | A board position where most lanes and hot spots are blocked, making it difficult to score or play bingos. Contrast with OPEN BOARD. |
| COLLINS | See COLLINS SCRABBLE WORDS (CSW / COLLINS / SOWPODS). |
| COLLINS SCRABBLE WORDS (CSW / COLLINS / SOWPODS) | The main word list used outside North America. See https://www.collinsdictionary.com/. |
| CONSOGRAM | A way of writing a word by separating consonants and vowels (e.g., RETINA → NRT + AEI). |
| CONSONANT-HEAVY | A rack (or bag) with too many consonants, making it harder to form words. |
| COUNTBACK | An end-of-game scoring adjustment: when a player goes out (plays their last tile), the total pip value of tiles remaining on the opponent's rack is added to the winner's score and subtracted from the loser's score. |
| COUNTER | A high-point tile (typically worth 5 or more points), such as J, Q, X, or Z. |
| CSW | See COLLINS SCRABBLE WORDS (CSW / COLLINS / SOWPODS). |
| DEFENDER | A word ending with a letter like C or V that does not form common two-letter words in North American play, making it harder to hook. Note: this usage is not standard across all clubs. |
| DLS (DOUBLE LETTER SCORE) | A square that doubles the value of a single letter. |
| DLS-DLS | See DOUBLE-DOUBLE (FOUR-TIMER). |
| DOUBLE CHALLENGE | A rule (used in North America) where an incorrect challenge results in losing your turn. |
| DOUBLE LETTER SCORE | See DLS (DOUBLE LETTER SCORE). |
| DOUBLE WORD SCORE | See DWS (DOUBLE WORD SCORE). |
| DOUBLE-DOUBLE (FOUR-TIMER) | A play that covers two double word squares, scoring four times the word value. |
| DOUBLE-TRIPLE | A play that covers both a double-letter score and a triple-word score, yielding a 6x letter bonus for the tile placed on the double-letter score. |
| DUMP | Playing off unwanted tiles to improve your rack. |
| DUPLICATE | A Scrabble format in which all players face the same rack of tiles on the same board position each turn. After each play is announced, every player makes their own independent choice, and the scores are compared. Because luck is equalized, duplicate rewards pure board vision and word knowledge over draw luck. TSH supports duplicate natively; the format is more common in Europe than North America. |
| DWS (DOUBLE WORD SCORE) | A square that doubles the total value of a word. |
| ENDGAME | The final stage of the game when all tiles are known and no tiles remain in the bag. |
| ENTROPY | A measure of how much the score is likely to change — how "swingy" a game position is. |
| EQUITY | The true value of a move, accounting for its score, the quality and synergy of the tiles you keep (leave) with each other and the tiles on the board, and board position. The highest-equity play is not always the highest-scoring one. |
| EXCHANGE (CHANGE / "PASSING N") | Trading tiles instead of playing a word. Allowed only if at least 7 tiles remain in the bag. |
| EXTENSION | Adding letters to the front or back of an existing word (e.g., CHANT → PENCHANT). A one-letter extension is called a "HOOK." |
| FALSE WORD | See PHONY (PHONEY / FALSE WORD/ NON-GO). |
| FAST BAGGING | See PREMATURE DRAW (FAST BAGGING). |
| FLOATER | A useful letter already on the board that can help form longer words. |
| FOUR-TIMER | See DOUBLE-DOUBLE (FOUR-TIMER). |

| HOT SPOT | An area of the board where a high-scoring play is possible. |
| ILLEGAL PLAY | A move that violates the rules of board formation or procedure. |
| IRREGULARITY | Any deviation from proper procedure, including misdraws, misplays, or scoring errors. |
| KEEP | See LEAVE (KEEP). |
| KIBITZ | To watch or comment on a game in progress, often by a spectator offering unsolicited advice. Frowned upon in competitive clubs and tournaments. |
| KITCHEN-TABLE PLAYER (PARLOR PLAYER) | A player who does not play Scrabble extensively or regularly and typically has not had study or instruction beyond the printed rules with the game. |

| NATURAL BINGO | See NATURAL (NATURAL BINGO). |
| NEUTRALIZE (THE CLOCK) | To stop both players' clocks during a game interruption — such as a challenge or a director ruling. Either player may neutralize by pressing the clock button on their opponent's side. Time does not run while the clock is neutralized. |

| SPREAD | See MARGIN (SPREAD). |
| STAIR-STEP (STAIRCASE) | See LADDER. |
| STAIRCASE | See LADDER (STAIR-STEP / STAIRCASE). |

| STEM | A group of (typically 6 or 7) letters that can form many bingos when combined with one more letter. See the bingo stems study page on this site. |
| STICK | See Q STICK. |
| STOP (STOPPAGE) | Any interruption where the clock is neutralized for a ruling or correction. On most digital clocks this is done by hitting a button in the middle of the clock. |
| SYNERGY | The property of a rack where the tiles work well together to form words. A rack with good synergy has tiles that combine easily into bingos or high-scoring plays. |

| UNSEEN (POOL) | Tiles not yet visible (still in the bag or on your opponent's rack). |
| VOLATILITY | The degree to which a game position is subject to large score swings. A player who is behind often seeks high volatility — opening the board to create scoring opportunities — while a player who is ahead prefers low volatility to protect their lead. Related to ENTROPY. |
| VOWEL CONSONANT RATIO | The balance of vowels and consonants in your rack or leave. |
| VOWEL DUMP | Playing mostly vowels to fix a vowel-heavy rack. |

| TERM | DEFINITION |
|---|---|
| ALPHA PAIRINGS | A pairings report sorted alphabetically by player name, as opposed to RANK PAIRINGS (sorted by current standing). Used at check-in and posted on the wall so players can quickly find their own name. |
| APPEAL | A request for a ruling to be reviewed by a higher authority such as a head director or appeals committee. |
| APPEALS COMMITTEE | A group designated to review disputed rulings; their decision is final within the tournament. |
| AUTOPAIR | A tournament-software feature that automatically generates pairings as soon as all scores for a round are entered, without requiring a director to issue a separate command. |
| BASD (BIG APPLE SHOWDOWN FORMAT) | A specialized 20-player tournament format developed for large invitationals. The first nine rounds use Integrated Flight (IF) pairings — a structured Swiss-based schedule. Round 10 is a semifinal bracket for the top eight players, followed by championship finals rounds. Exactly 20 players are required; the format cannot accommodate more or fewer. |
| BRACKET (SINGLE ELIMINATION) | A tournament format in which players are seeded and paired bracket-style: the loser of each game is eliminated and the winner advances. Sometimes used for the final rounds of a tournament after preliminary Swiss rounds. |
| BYE | A round in which a player has no opponent and receives an automatic win. The score credited for a bye is set by the tournament director (commonly 50 points of spread). Players are typically assigned a bye by the software when the total player count is odd; the lowest-ranked eligible player receives it first. |
| BYE METHOD | The rule the tournament director sets for which player receives an automatic bye when the field has an odd number of players. Common options: bottom-up (lowest-ranked eligible player), top-down (highest-ranked eligible player, rare), and German style (rotating among players who haven't yet received a bye). The specific method is chosen by the director before the tournament and typically stays fixed throughout. |
| CHEW PAIRINGS | The default "smart routing" system in TSH (named for its designer). Rather than a single algorithm, Chew automatically selects the appropriate pairing method for each round: a balanced opening schedule for round 1, Swiss for middle rounds, and KOTH for the final rounds (when configured). Directors who choose Chew do not need to switch pairing modes manually — the software transitions between modes based on rounds remaining and tournament state. Most tournaments use Chew without ever knowing it. |
| CLASS (PRIZE CLASS) | A subdivision of a division used for prize purposes. Players are grouped into classes (e.g., Class A, Class B) based on pre-tournament rating, so that prizes are awarded within rating bands rather than only to the top overall finishers. |
| CLASS ENDAGONY | A pairing constraint that forces players to face opponents from within their own rating class whenever possible. Used in tournaments where prize money is structured by class (Class A, Class B, etc.) and the director wants class standings to reflect direct head-to-head results rather than cross-class games. |
| CLOCK MALFUNCTION | A failure of the game clock requiring director intervention and possible reconstruction of time. |
| COFFEE-HOUSING | Attempting to distract or mislead an opponent through table talk, exaggerated reactions, false hesitation, or other unsportsmanlike behavior. Classified as distracting or misleading conduct under NASPA tournament rules, which require all players to refrain from speech or behavior that is distractive or misleading during a game. |
| CONFIRMED SCORE | A game result that has been accepted by both players. Contrast with PROVISIONAL SCORE. Most tournament software requires confirmation before a result affects official standings. |
| CONSECUTIVE REPEATS | A pairing constraint limiting how many rounds in a row two players can face each other. A setting of 1 means no player may face the same opponent in back-to-back rounds; a setting of 2 means they can be paired twice consecutively but not three times in a row. Configured by the tournament director. |
| CROSS-TABLES | A website recording tournament results, ratings history, and player statistics for NASPA-sanctioned events. See https://www.cross-tables.com/. |
| CUM (CUMULATIVE SCORE) | A player's running point total across all games in a tournament. Used as a tiebreaker when two players have the same win-loss record: the player with the higher cumulative score ranks higher. |
| CUMULATIVE SCORE | See CUM (CUMULATIVE SCORE). |
| DEAD GAME | A game whose outcome cannot affect the final standings — for example, when a player has been GIBSONIZED. Directors may allow dead games to be played for prize or rating purposes, or may instruct players to sit out. |
| DELAY OF GAME | Unreasonable slowing of play; may result in warnings or penalties. |
| DIRECTOR (TD) | The official responsible for administering a tournament, enforcing rules, and making rulings. |
| DIRECTOR'S DISCRETION | Authority granted to a tournament director to make rulings in situations not explicitly covered by the written rules. When a director exercises discretion, that decision stands for the remainder of the tournament. |
| DIVISION | A separate grouping of players within a tournament, typically based on rating (e.g., Open, Club, Novice). Each division has its own pairings, standings, and prizes. Players in different divisions do not play each other. |
| DOUBLE ELIMINATION | A bracket format in which a player must lose twice before being eliminated. Players who lose in the winners' bracket move to a losers' bracket, where they get a second chance. The format is longer than single elimination but more forgiving. |
| DRAW (GOING FIRST) | The process of determining which player takes the first turn. In most tournaments, each player draws a tile at the start of the game; the player whose tile is alphabetically earlier (or is a blank, which beats any letter) plays first and returns both tiles to the bag before play begins. |
| ELO | A rating algorithm (originally developed for chess) that assigns numerical ratings based on game results. NASPA and WGPO use a modified Elo system: beating a higher-rated opponent gains more rating points than beating a lower-rated one. |
| EXAGONY | A pairing constraint used in team Scrabble tournaments that prevents players from the same team being paired against each other. From the French "agoniser" (to suffer) — exagony means your teammates are spared the agony of playing you. The constraint is enforced by the pairing software throughout the tournament. |
| FLIGHT | A subgroup of players within a division who are paired only against each other, typically for scheduling convenience (e.g., players arriving at different times, or a very large field split across multiple rooms). |
| FLOOR DIRECTOR | An assistant to the tournament director who handles rulings and logistics during play. |
| FLOOR TD | See FLOOR DIRECTOR. |
| FORFEIT | A game awarded to one player due to the opponent's absence or withdrawal. |
| GIBSONIZATION | The condition in which a player has clinched first place — their lead in wins and spread is mathematically insurmountable regardless of remaining results. Named for David Gibson. Once a player is Gibsonized, the pairing software isolates them from the competitive field: if the number of Gibsonized players is even, they are paired against each other in KOTH order; if odd, the extra Gibsonized player is paired against a low-ranked opponent (typically the player with the fewest prior games against any Gibsonized player) so that competitive pairings are not disrupted. |
| GIBSONIZED | Having won enough games to clinch a tournament win before the final round(s), so that the outcome is mathematically decided regardless of remaining results — named after David Gibson. The Gibsonized player can play freely with no pressure, while their opponent has nothing to lose and may take risks they would otherwise avoid, so players with tournament winnings at risk are typically paired against each other instead. |
| HEAD-TO-HEAD (H2H) | The direct win-loss record between two specific players. Used as a tiebreaker when players are tied on wins and cumulative spread: if the tied players played each other, the player who won that game ranks higher. |
| HOLD ABUSE | Excessive or strategic use of holds to disrupt play; may be penalized. |
| HOUSE PLAYER | A player — often the tournament director or a volunteer — added to the field to make an even number of players so no one receives a bye. A house player typically does not compete for prizes or ratings credit. |
| INITIAL SEEDING | The ranking assigned to each player before any games are played, based on their pre-tournament rating. Initial seeding determines the first round's pairings and the board/table assignments. |
| INTEGRATED FLIGHT (IF) PAIRINGS | A hybrid pairing system that divides players into two or more "flights" (groups) and uses a round-robin-style rotation within each flight, while allowing cross-flight pairings when schedules align. Used in the preliminary rounds of some large invitationals (including BASD) to ensure a balanced schedule before bracket or finals play begins. |
| KING-OF-THE-HILL (KOTH) | A pairing format used in the final rounds of a tournament in which the top-ranked player is always paired against the second-ranked player, the third against the fourth, and so on. This ensures that the championship contenders face each other directly and that the tournament result is settled on the board. |
| KIOSK MODE | A restricted data-entry mode in tournament software that allows players to enter their own scores from a shared terminal, but prevents access to director-only functions. Often protected by a player PIN or password. |
| KOTH WITHOUT REPEATS | A variant of King-of-the-Hill in which the top-ranked player is paired against the highest-ranked player they have not yet faced, rather than simply the second-ranked player. If the #1 and #2 seeds have already played, #1 is paired with #3, and so on down the standings. Used when repeat games are undesirable even at the top of the standings. |
| LATE ENTRY | A player who registers after a tournament has begun and is added to the field mid-tournament. Late entries are assigned a bye (or byes) for any rounds already played before they joined, and are paired normally in subsequent rounds. |
| OVERTIME | Exceeding your allotted time, usually resulting in point penalties. |
| PAIRINGS | The list of game matchups for an upcoming round: who plays whom, at which board, and who has first move. Pairings are generated by the tournament director (or automatically by software such as TSH) and posted before each round begins. |
| PERFORMANCE RATING | An estimated rating calculated from a player's results in a single tournament, based on the ratings of their opponents and the outcomes of each game. Used to gauge how a player performed relative to the field, even if the result doesn't change their official rating significantly. |
| PRIZE BAND | A range of standings positions that all receive equivalent prizes — for example, a tie prize covering 2nd and 3rd place when there is not enough money to give separate prizes to each. |
| PROCEDURAL PENALTY | A penalty assessed for violating tournament procedures rather than word validity. |
| PROVISIONAL SCORE | A game result that has been entered by one player but not yet confirmed by the opponent. Provisional scores may appear in standings but are subject to correction. Contrast with CONFIRMED SCORE. |
| QUARTILE PAIRINGS | A pairing method that divides the field into four equal groups (quartiles) by standing and pairs players across quartiles — top of quartile 1 vs. top of quartile 2, top of quartile 3 vs. top of quartile 4, and so on. Produces more balanced early matchups than pure Swiss and is sometimes used for opening rounds of large tournaments. |
| RANDOM PAIRINGS | A pairing method that assigns opponents randomly, subject to the same repeat and consecutive-repeat constraints as Swiss. Used for round 1 of some tournaments (where no prior results exist to rank players) or for exhibition rounds where competitive balance is less important than variety. |
| RANK PAIRINGS | A pairings report sorted by current standing (rank), showing the highest-ranked players at the top. Contrast with ALPHA PAIRINGS. Rank pairings help players see where they stand relative to their opponent. |
| RANKING | A player's position in a rating system based on tournament results. |
| RATING | A numerical measure of a player's skill based on past performance. |
| RECONSTRUCTION | Rebuilding the game state after a major irregularity involving tiles, score, or board. |
| REPEATS (PAIRING CONSTRAINT) | A director-set limit on how many times two players may face each other during a tournament. A repeat limit of 0 means no player may face the same opponent twice; 1 means they may play a maximum of two games against each other; and so on. TSH enforces this constraint when generating pairings and will break the limit only as a last resort if no legal pairing is otherwise possible. |
| ROUND ROBIN | A tournament format in which every player faces every other player exactly once (in a complete round robin) or a set number of times. Common for small tournaments or club nights. Pairings are pre-scheduled using a rotation algorithm (Berger or Clark schedule). |
| RULING | An official decision made by the director regarding gameplay or disputes. |
| SCORE CORRECTION | An adjustment made to fix an arithmetic or recording error. |
| SCORE SLIP (TALLY SLIP) | A physical form used to record the result of a game. At the end of each game, both players write the final score, sign, and submit the slip to the director or enter it into the tournament software. Pre-printed slips often show the round, board number, and player names. |
| SINGLE ELIMINATION | See BRACKET (SINGLE ELIMINATION). |
| SOURCE ROUND | The round whose standings are used to generate pairings for the next round. Normally this is the most recently completed round. In session-based tournaments (where a break separates groups of rounds), the source round may be set back to the start of the current session so that pairings reflect only that session's results. |
| SPREAD CAP | A per-game limit on the spread that counts toward standings and pairing calculations. For example, with a spread cap of 150, a game won by 300 points only contributes 150 points to cumulative spread. Caps prevent a single blowout game from distorting the standings — and therefore who players face in subsequent rounds. The actual game score is always recorded in full; the cap affects only the ranking and pairing calculations. |
| STANDINGS | The current ranked list of all players in a division, sorted primarily by wins and secondarily by cumulative spread (and further tiebreakers if needed). Standings are updated after each round and posted for players to review. |
| STRENGTH OF SCHEDULE (SOS) | A tiebreaker metric measuring the average quality of opponents a player has faced. A player who has beaten stronger opponents ranks higher on SOS than a player with the same record who faced weaker opponents. |
| SWISS PAIRING | A pairing system used in most competitive Scrabble tournaments. At the start of each round, players are sorted by record and grouped into "win groups" — all players with 5 wins in one group, all with 4 wins in another, and so on. Within each win group, the software pairs players to minimize rematches and balance the advantage of going first. When a win group has an odd number of players, one player is moved up or down from an adjacent group to complete the pairings. The player who has the fewest options for opponents (due to repeat restrictions) is paired first, working outward to reduce dead ends. Swiss is designed so that players with similar records always face each other, naturally separating the field over many rounds without the elimination of bracket formats. |
| TALLY SLIP | See SCORE SLIP (TALLY SLIP). |
| TIEBREAKER | A secondary ranking criterion used to separate players with identical win-loss records. Common tiebreakers (in order): cumulative spread, head-to-head result, strength of schedule, and coin flip. The specific tiebreaker order is set by the tournament director. |
| TIME ADJUSTMENT | A correction to one or both players' clocks ordered by a director. |
| TIME PENALTY | Points deducted for going into overtime. |
| TOURNAMENT DIRECTOR | See DIRECTOR (TD). |
| TSH (TOURNAMENT SCRABBLE HANDLER) | The standard software used to administer competitive Scrabble tournaments in North America. TSH manages pairings, score entry, standings, and report generation. Written in Perl by John Chew; current version is 3.340+. |
| WALL CHART | A matrix display — posted on a wall or projected — showing every player's results across all rounds: rows are players (sorted by final standing), columns are rounds, and each cell shows the opponent's board number and the result (win/loss/bye) or score. A standard fixture at Scrabble tournaments. |
| WARNING | A formal notice issued by a director for minor infractions. |
| WIN GROUP | A set of players who have the same number of wins at a given point in a Swiss tournament. Swiss pairings are generated by pairing players within the same win group against each other — 5-win players face 5-win players, 4-win players face 4-win players, and so on. When a win group has an odd number of members, one player is temporarily moved into an adjacent group to complete the pairings. See also SWISS PAIRING. |
| WITHDRAWAL | A player leaving a tournament before completion. |
| WORD JUDGE | An official or electronic referee used in tournament play to adjudicate word challenges. |
