Domineering
Place dominoes and leave your opponent without a move.
How to play Domineering
Pink starts and places vertical dominoes; Blue places horizontal ones. Against the computer, choose Your tiles to play either side. Choosing horizontal lets the computer start. Each domino occupies exactly two empty neighboring squares.
Tap the top square for Pink or the left square for Blue. Dominoes stay where placed. If you have no legal placement on your turn, you lose.
Example: Vertical ↕ · horizontal ↔
