The player can continue to play tiles on a single turn so long as there are legal moves. Additional plays do not need to use tiles played earlier in the turn, but it may be useful to "build" equations so that difficult high-value tiles can be played. Once a player no longer has legal moves, has played all of the tiles on the rack, or chooses to stop, the turn is finished, the player's score is recorded, and the player draws new tiles from the pouch until the rack has seven tiles again.
