===Gameplay===
On every turn, the player at turn can perform one of the following options:
* Pass, forfeiting the turn and scoring zero.
* Exchange one or more tiles for an equal number from the bag, scoring zero. This can only be done if 7 or more tiles remain in the bag.
* Play at least one tile on the board, adding the value of all words formed to the player's cumulative score.

The first play of the game must consist of at least two tiles and cover the center square (H8). Any play thereafter must use at least one of the player's tiles to form a "main word" (containing all of the player's played tiles in a straight line) reading left-to-right or top-to-bottom. Diagonal plays are not allowed. At least one tile must be adjacent (horizontally or vertically) to a tile already on the board. If the play includes a blank tile, the player must designate the letter the blank represents; that letter remains unchanged for the rest of the game unless the play is challenged off. The player announces the [[#Scoring|score]] for that play, and then draws tiles from the bag equal to the number of tiles played, so that there are seven tiles on their rack. If there are not enough tiles, the player draws any remaining tiles instead. If the game is played using a [[Chess clock|clock]], the player starts the opponent's clock after announcing the score and before drawing tiles. Players may [[Tile tracking|keep track of tiles]] played during the game.

If a player has made a play and not yet drawn a tile, any other player may choose to challenge any or all words formed by the play. The challenged word(s) are then searched in the agreed-upon word list or dictionary. If at least one challenged word is unacceptable, the play is removed from the board, and the player scores zero for that turn. If all challenged words are acceptable, the challenger loses their turn. In tournament play, players are not entitled to know which word(s) are invalid or the definitions of any challenged words. Penalties for unsuccessfully challenging an acceptable play vary in club and tournament play and are described in greater detail below.

====End of game====

The game ends when either:
* One player has played every tile on their rack ("playing out") and no tiles remain in the bag (regardless of the tiles on the opponent's rack).
* At least six successive scoreless turns have occurred and either player decides to end the game. This typically occurs at the end of the game when neither player can form a valid play. (For several years, a game could not end with a cumulative score of 0–0, but that is no longer the case, and such games have since occurred a number of times in tournament play, the winner being the player with the lower total point value on their rack and thus a score less negative than the opponent's.<ref>{{cross-tables player-tournament|pid=560|pname=Marlon Hill|tid=6898|tname=Albany, NY July 2010}}</ref>)
* In tournament play, when either player exceeds 10 minutes of overtime.

At the end of the game, each player's score is reduced by the sum of the values of their unplayed tiles; if a player plays out, the sum of all other players' unplayed tiles is added to that player's score. This rule differs slightly in most tournaments; a player who plays out adds twice this sum, and the opponent's score is unchanged.
