Which tiles are free
A tile is free when nothing sits on top of it and either its left or right edge is open. Everything else has to wait until a neighbour is removed.
This is the turtle: 144 tiles stacked in the familiar shell shape, cleared by matching identical free pairs. It is a tile game rather than a card game, and it rewards reading the stack before you touch it.

Match two identical tiles to remove both. Flowers match any flower and seasons match any season — those are the only tiles that do not need an exact twin.
A hint highlights one legal pair. If no pair is left but tiles remain, a shuffle reshuffles the board so the game can continue rather than ending in a dead position.
