Rummy Drop - Version 1.23 Rummy Drop combines the fast action of Tetris with the card-playing logic of Solitaire. As your card begins to fall, you move it over the seven stacks using the arrow keys, or swap it for another one using the space bar. Score points by stacking three of a kind or a straight flush and causing the cards to collapse. The game ends when there's no room for the next card to fall. Rummy Drop 1.23 includes sound effects, a high score list, online help, and 4 different ways to play.
