What this game is
Two players. Don’t take the last mark! Don’t take the last mark!
How to play
A very old game for two players on the same device. Player 1 is blue and Player 2 is pink. On your turn, cross out as many marks as you like, but only from ONE row. You must cross out at least one. The player who has to cross out the very last mark loses, so the other player wins!
Tap marks in one row to pick them, then press Cross out. Tap a picked mark again to unpick it. With a keyboard, use the arrow keys to move, Space to pick, and Enter or X to cross out.
