How to play
- Orange squares are dominoes that already stand. The one marked ▶ is pushed first.
- A falling domino knocks over every standing domino right next to it, up, down, left or right, and those knock over the next ones.
- Tap empty squares to place extra dominoes, up to the limit. Tap a blue domino again to take it back.
- You win when the chain reaches every orange domino. Grey rocks cannot hold a domino.
Controls: mouse or touch. Made by CalcoTools.
Tips and strategy
- Find which orange dominoes are cut off, then look for the shortest bridge of empty squares to reach them.
- Dominoes only knock over their four neighbours, not diagonals.
- One placed domino can bridge two gaps if it touches both sides.
- The limit is just enough, so look for bridges that serve more than one gap.
FAQ
- Does a domino knock over diagonal neighbours?
- No. Only the dominoes directly above, below, left and right of it.
- Is every level solvable?
- Yes. Each level is built from a connected shape with some squares taken out, and putting those back always works within the limit.
- Can I place more dominoes than I need?
- Up to the limit, yes. Extra dominoes never hurt, but you only get a limited number.
