Controls

You play by tapping tiles, or clicking them on a laptop. Tap one tile, then tap a matching tile to remove the pair. Tap a selected tile again to deselect it if you change your mind.

The one rule that governs everything is which tiles you are allowed to pick:

• A free tile is one with nothing stacked on top of it and at least one long side, left or right, open. Only free tiles can be selected, so freeing the tile you want is the real puzzle.
• Matching pairs removes them from the board. Every tile needs an exact twin with the same face; there's no partial or group matching to lean on.

You win by clearing every tile from the layout. If no free matches remain, tap Shuffle to remix the faces of what's left and open up new pairs (it costs a short rewarded ad).

A Help button explains the rules on demand, and Hint highlights a pair you can take right now if you get stuck.

Tips

• Free buried tiles before easy ones. Removing a pair that unlocks tiles underneath opens up the board, while clearing already-free pairs for no reason can leave key tiles trapped.
• Look at the whole layout before your first match. Knowing where all four copies of a tile sit lets you choose which pair to remove so you don't accidentally strand the other two.
• Clear tiles from the top of stacks. Tiles on top pin the ones below, so working downward keeps freeing new options instead of locking them away.
• Be careful with tiles you have four of. When all four of a kind are visible, matching the wrong two can leave the remaining pair buried on opposite ends. Match the ones that free the most.
• Prioritize opening the long edges. A tile becomes selectable when a side clears, so removing pairs along the outer edges tends to unlock the most tiles at once.
• Slow down near the end. The final tiles are where a board gets stuck. Checking that a match won't trap its twins keeps you from losing a nearly finished layout.
