How to play Trio Stack
Trio Stack is a layered tile-matching puzzle. Tiles are piled in stacks, and only the tiles that nothing covers can be tapped. Tap a free tile to send it to the tray, and match three of the same picture to clear them.
The tray has seven slots. If it fills up without a match, the level is over, so plan which layer to open next. Every level brings a new themed set of pictures, a bigger stack and more kinds to keep apart.
Watch an optional short video for a helper: undo your last tap, shuffle the tiles left on the board, or get a second chance after a loss. Your best score and level are saved on your device.
