Ways to play

Endless

Clear levels, earn stars, and face a boss every fifth level: The Sliver, The Baker, The Ghost and The Spinner.

Daily

Ten shapes, the same for everyone each day. One ranked try, then practise as much as you like.

Sprint

This week's 25 shapes against the clock. Every point of error costs a second, so rushing doesn't pay.

Weekly challenges

Three new goals every Monday, plus Golden Shapes to collect for your album and Game Center leaderboards.

Fair by design No ads, no tracking, no energy timers. Slivers are earned only by playing and can never be bought. Halves Plus is one optional purchase for cosmetics, and never changes your score.
