The goal of Parley is to end the game with the blue bar filled more than halfway. During your turn you can improve your position by selecting a tile which represents a given topic. You will receive points for the number shown, increasing the amount that the bar is filled. You will also receive points for any topic tile that shares the same topic as your selected tile and is also in the same row or column. Selecting the same topic as your previous turn will unlock one of four abilities: Reversal, Double Down, Shuffle, and Wipe. After each turn, the remaining tiles will advance and new tiles will be generated to fill the board.
