How to play
- Pick one of the three pieces under the board, then tap a triangle to set it down. Pieces are made of triangles pointing up and down, and they only fit where the points match the board.
- A row is complete when every triangle across it is filled. The slanted bands that run from the top edge to the bottom edge also clear when they are full.
- Clearing several lines with one piece multiplies the bonus, so setting up a double pays more than two singles.
- When none of the pieces left in your hand fit anywhere, the game ends. Your best score is saved on this device.

Tips and strategy
- Look at the points before you tap: a piece with an up triangle at its left edge needs an up triangle there on the board.
- The slanted bands are easy to forget. Fill one while you build a row and you may clear both at once.
- Keep single triangles open at the edges, because the one and two triangle pieces are what rescue a tight board.
- If a tap does not fit, try the triangle next to it: the piece shifts one column to match the points.
FAQ
- Why does a piece sometimes shift when I tap?
- A piece can only sit with its points matching the board, so a tap on the wrong kind of triangle moves the piece one column over.
- Can I rotate pieces?
- No. Pieces keep the orientation shown, which is what makes planning ahead worthwhile.
- Is my best score saved?
- Yes, on this device only. Nothing is sent anywhere.
