Drag inward from any edge of the sheet. That side folds over, and the tiles it carries land on top of the tiles below. Three of a colour stacked directly on top of each other clear. Every fold leaves a smaller sheet in a different shape.
- The fold carries
- Every tile on the folded side travels with the paper and lands on whatever cell it meets.
- Three touching
- Three of a colour in a row inside one pile pop. A different colour wedged between them blocks the run, so the order tiles land in is the whole game.
- Read the pile
- The bar on a tile lists what is stacked there, bottom to top. While you drag, each landing cell shows the pile it is about to hold, and any triple in it is ringed.
- Small side folds
- You can only fold the shorter half over the longer one, so every landing cell is obvious.
- Gaps close
- When a run pops, the tiles above drop onto the ones below. If that makes another three in a row, it pops too, and the chain keeps going.
- Clear the sheet
- The level is won when no tiles are left. Fold into a single cell with tiles on it and it is lost.
