A heap of patterned cubes, a collection bar at the bottom with seven slots, and one rule: three of a kind clear. Fill all seven slots with mismatched cubes and the game ends.

The relaxing presentation hides a real squeeze. Every cube you take that does not complete a triple costs you a slot, and slots do not come back except by matching. Two careless picks early and you are playing the rest of the board with three slots instead of seven.

Play it like Magic Sort: free space is the resource. Only pick a cube if you can already see its two partners, or if it completes something. Speculative picks are how runs end.

There is an undo and a shuffle if you need them, and no timer at all — the pressure comes entirely from the bar.
