Crossword Game Notation Explained — How to Read and Write Scrabble Game Records
Every competitive Scrabble game is recorded using a standardized notation system that allows any player to replay the entire game move by move. Whether you're studying published games from world championships, sharing your own games online, or reviewing your plays with analysis software, understanding Crossword Game Notation (CGN) is essential. This guide explains the complete system from first principles.

What Is Crossword Game Notation (CGN)?
Crossword Game Notation is the standard format for recording Scrabble games, adopted by tournament organizations worldwide including NASPA (North American Scrabble Players Association) and WESPA (World English-Language Scrabble Players Association). Each move is recorded as a single line containing the position, direction, word played, and score. The notation is compact enough to write by hand during tournament play and precise enough for computer analysis software to reconstruct the exact board state at any point in the game.
💡 Why Notation Exists
CGN serves three purposes: post-game analysis (reviewing your mistakes), sharing games (publishing notable plays or full games), and AI review (feeding games into analysis software that identifies optimal plays).
The notation was formalized in the 1980s as tournament play grew and players needed a way to study games after the fact. Before notation, knowledge died at the table. After notation, every game became a learning resource.
The Coordinate System — Rows 1-15, Columns A-O
A standard Scrabble board has 15 rows and 15 columns, creating 225 squares. Columns are labeled A through O from left to right. Rows are numbered 1 through 15 from top to bottom. Every square on the board has a unique coordinate combining its column letter and row number — for example, H8 is the center square (column H, row 8).
📐 Horizontal (Across) Plays
Written as ROW then COLUMN of the starting square: 8G means "starting at row 8, column G, going right." The number comes first.
📐 Vertical (Down) Plays
Written as COLUMN then ROW of the starting square: G8 means "starting at column G, row 8, going down." The letter comes first.
The direction convention is elegant: if the letter comes first (like G8), the play goes down that column. If the number comes first (like 8G), the play goes across that row. This single rule eliminates all ambiguity about direction.
Recording a Play — Position, Direction, Word, Score
Every standard play in CGN contains four components written in sequence: the starting coordinate (which encodes direction), the word played, and the score. Tiles already on the board that the word passes through are indicated with parentheses or lowercase letters in some notation variants. A blank tile used in the play is indicated by writing the represented letter in lowercase.
🧩 Play Format Examples
8G QUARTZ 92 — Horizontal play starting at row 8, column G. Word is QUARTZ. Score is 92.
H4 JESTING 76 — Vertical play starting at column H, row 4. Word is JESTING. Score is 76.
12A BREATHe 89 — Row 12, column A, across. The lowercase 'e' indicates a blank tile representing E.
8H STAR 8 — The classic first move (center square). Row 8, column H, across. STAR scores 8 (S=1+T=1+A=1+R=1, doubled on center DWS).
Special Notations — Exchanges, Challenges, and Passes
Not every turn results in a word being placed on the board. CGN includes standard notation for three non-play actions: exchanging tiles, challenging an opponent's word, and passing your turn. Each has a specific format that records what happened without revealing hidden information.
EXCH 5: Player exchanged 5 tiles. The specific letters are not recorded (to prevent information leakage in tournament settings). Written as "EXCH" followed by the count. Score for the turn is 0.
CHAL+ (or CHAL-): A challenge was issued. CHAL+ means the challenge was successful (word was invalid, play removed). CHAL- means the challenge failed (word was valid, challenger loses turn in some rule sets).
PASS (or -): Player passed their turn without playing or exchanging. Three consecutive passes from both players ends the game under standard rules.
Reading a Published Game Record — Step by Step
A complete game record lists every move in sequence, alternating between the two players. Reading one requires mentally (or physically) placing each word on the board in order. Here is a worked example of the first 6 moves of a game, demonstrating how notation translates to board state.
6-Move Example
Player 1 vs Player 2 — Opening Sequence
1. P1: 8D STRANGE 66 (bingo!)
2. P2: D8 QI 22
3. P1: 9C WAXEN 42
4. P2: 7D ZAP 36
5. P1: EXCH 4
6. P2: 11C JOVIAL 38
Move 1 places STRANGE horizontally starting at row 8, column D (covering the center DWS). Move 2 places QI vertically starting at column D, row 8 (hooking onto the S). Each subsequent move builds on the existing board. The exchange on move 5 shows Player 1 had a poor rack after the bingo and chose to refresh.
Why Notation Matters for Improvement
Recording your games and reviewing them afterward is the single most effective practice method for improving at Scrabble. Post-game analysis reveals patterns invisible during play: positions where better words existed, leave errors that compounded over multiple turns, and positional mistakes that gifted your opponent high-scoring opportunities.
📊 Post-Game Analysis
Feed your game record into analysis software. It shows the optimal play for each turn and calculates your equity loss per move.
🤝 Sharing Games
Post annotated games to Scrabble forums. Other players can review and comment on key decision points.
🧠 Pattern Recognition
Reviewing 50+ of your own games reveals recurring mistakes. Maybe you always waste S tiles or miss hooks in column A.
🏆 Study Champion Games
World championship games are published in notation. Study expert plays to learn positional concepts and word choices.
Tools for Recording Games — Apps and Paper Methods
Modern players have multiple options for recording games, ranging from smartphone apps that auto-track everything to simple paper tracking sheets that require just a pen and 30 seconds per turn. The best method is whichever one you'll actually use consistently.
Paper scoresheet: Print a standard CGN scoresheet with columns for move number, player, position, word, and score. Write each move as it's played. Takes approximately 10 seconds per turn.
Digital apps: Apps like Woogles, CrosswordTournaments, and ISC automatically record games in real time. Export as .gcg files for analysis software.
Post-game reconstruction: Take a photo of the final board and reconstruct moves from memory. Less accurate but better than no record. Works for casual games.
Voice recording: Dictate each move into your phone ("8G QUARTZ 92"). Transcribe later. Minimal disruption to game flow.
💡 Start Simple
You don't need to record every game perfectly. Start by recording just your plays (not your opponent's) with approximate positions. Any record is better than none — even partial notation reveals patterns in your play over time.
