You play on a 6×6 board, and each turn three random numbers between 1 and 9 are placed in three random empty spots on the board. The player at this time can select a number and drag it around the board, only passing across empty spots. At each step, the number decreases and leaves a “1” behind it. At the end of the turn, all matching numbers are removed from the board, and three new numbers appear. The game ends when there aren’t possible moves.
