Type the tiles the other game gave you. Use ? for a blank.
Type the whole word as it reads on the board, including letters that were already there. It starts on the square you tapped.
Tap the tiles to throw back. You draw the same number and your turn ends.
Place tiles by dragging them from your rack to the board, or tap a rack tile and then tap a square.
Type a word: tap an empty square to set an arrow (tap again to switch between across and down), then type on a keyboard or tap rack tiles in order. Backspace takes the last one back.
Take tiles back by tapping them on the board, dragging them to the rack, or pressing Recall (Esc).
Blanks ask which letter they stand for. They score zero.
Hint shows the best play in faded green. Tap any of its tiles to place the whole word, then press Play, or move tiles first if you like.
Score preview appears on the board as you build a play. Press Play or Enter to submit.
Exchange needs at least 7 tiles left in the bag. Six scoreless turns in a row end the game.
Double challenge mode: invalid words can stand if nobody challenges. A challenged invalid play comes off the board; a wrong challenge costs the challenger a turn.
Opponents: Kitchen Table and Club play everyday words. Strong and Expert know the whole word list and value the tiles they keep. Master simulates the replies to its best candidates and searches the endgame, so it takes a few seconds per move.
Analysis mode (choose it in New game) is for field-testing Master against a game you play somewhere else. Enter your rack, press Suggest and Master shows its best move on the board plus a ranked list under Top moves. Tap the move to place it, then Play to record it and enter your new tiles. On their turn, tap the square where their word starts and type it (including letters already on the board), or use Their move. Tap a tile you entered to mark it as a blank. If a blank was recorded as a letter (or the reverse), double-tap that tile on the board during your turn to switch it; every score it touched is recalculated. Undo takes back any recorded move. Note that Tileworks uses the ENABLE word list, which differs a little from the lists other games use.
Game end: when a player uses all tiles and the bag is empty, that player gains the value of everyone's remaining tiles, and each other player loses their own.
