The matching game, not the four-player one. The tiles are stacked in a pile and you take them off two at a time: tap a tile, then tap its twin. Clear the whole pile to win.
You can only take a tile that is open: nothing on top of it, and its left or right side clear. Two tiles match when they show the same face. Any flower matches any flower and any season matches any season. Tap a raised tile again to put it down.
Hint lights up a pair you can take. Shuffle redeals what is left when you are stuck, in a way that can always be finished. Undo takes back as many moves as you like. Every deal can be cleared without a shuffle if you find the way.
changing the pile deals a new game. the turtle likes a wide screen; turn a phone sideways, or play the tower
show matches lights the open twins of the tile you raise

Sounds covers the tile noises, and the slider next to it covers everything. Music plays soft ambient music. Night mode warms the screen for a dark room. Chill mode turns all three on for late nights. Every switch is remembered on this device.
