Click to place a domino on the board. Use the arrow keys or scroll your mouse to rotate it. Your goal is to knock over all the crowned dominoes in the level. When you are ready, press the play button or press Space to activate the finger and start the chain reaction.

Use your dominoes wisely, because you only have a limited number for each level. To remove a domino you've placed, cover it with your transparent domino and click on it.
