Relaxing and easy to play, yet challenging strategic puzzle.
- Game consists of turns. Each turn starts when random domino taken from the set falls from the top of the game area.
- While a domino is falling it can be dropped down, moved left or right and rotated either way unless it's touching a wall or another domino.
- When a domino comes to the lowest unoccupied spot it stops. Horizontal domino overhanging a gap may overturn and fall down further if there is room for that.
- Resting domino can partially or fully annihilate with surrounding dominoes.
- Annihilation occurs when two or more domino halves of same value, but from different dominoes, arranged horizontally or vertically, or three or more form a diagonal.
- Annihilated domino halves disappear and other dominoes can fall down to fill gaps, possibly causing cascade of matches.
- A turn ends when all dominoes in the game area come to rest. Total number of annihilated domino halves forms the turn score.
- Max score is the highest turn score achieved in a game.
- Power score is the total of power points achieved in a game, where power points are awarded each turn as (turn score - 1)², e.g. 1 power point for matching 2 domino halves, 4 for matching 3 halves, etc.
- Speed score is a power score per minute.
- Try to build a long cascade of matches during a single turn to get the best max score.
- Match as many domino halves as possible each turn to achieve the best power score.
- Play quickly as possible to get a good speed score.
- Norm is the classic set of 28 dominoes marked with 0-6 spots on each half of a domino.
- Max is extended set of 55 dominoes marked with 0-9 spots on each half of a domino.
- Sprint is a short game where you play with a single domino set (norm or max). The game ends when all dominoes in a set have been played.
- Marathon gives you unlimited number of domino sets. Every new set is generated as soon as previous one runs out of dominoes. The game ends when there is no free space for next domino at the top of the game area.
