Tile match (often called triple tile) is a calm puzzle about collecting sets of three. A pile of picture tiles sits in the middle of the screen, and a tray with seven slots sits underneath. Move tiles into the tray; whenever three tiles with the same picture are in it, they clear away. Clear the whole pile before the tray fills up.
Which tiles you can pick
Tiles are stacked in layers, slightly offset, like a pile of cards. A tile is free when nothing lies on top of it, not even partly. Only free tiles can be tapped. In Stackfold, tiles you can't pick yet are shaded, so the free ones stand out.

Every tile you take away may uncover others, so the pile opens up as you go.
How the tray works
- Tap a free tile and it moves into the tray. Tiles with the same picture line up next to each other.
- When three of the same picture are in the tray, they clear away, freeing three slots.
- The tray has seven slots. If all seven fill up without a set to clear, the level is lost.

So the game is about two things at once: uncovering the tiles you need, and never letting the tray fill with odd tiles.
Winning a level
You win when every tile is gone from the board and the tray is empty. In Stackfold the bar at the top shows how many tiles are left. Levels start small (9 tiles in a neat block) and grow to more than 100 tiles stacked up to six layers high.
Your first levels: three habits
- Look before you tap. Find pictures that have three free copies right now. Taking all three is a free set.
- Finish sets you've started. A pair in the tray is a job half done; look for the third before you start a new picture.
- Keep at least two slots free. With five tiles in the tray, every tap matters; stop and plan.

The helpers
Stackfold has three helpers, each free once per level:
- Undo takes back your last move.
- Magic clears a set of three for you, taking the missing tiles from anywhere on the board.
- Shuffle deals new pictures to the tiles left, still with a way through.
A short video gives one more use of any helper. If the tray does fill up, you can watch a video to go back three moves (once per level), or simply try again. We explain when each helper is worth using.
Every level can be cleared
Each Stackfold level is dealt so that at least one order of taps clears the whole board, with no luck needed. If a level feels hopeless, the answer is a different order, not a lucky draw.
