About
Large shapes in many colours fill the board. Tap one and it bursts into smaller copies of itself; keep tapping the fragments until they pop. The trick is that you may not tap just anything.
The hub in the middle of the board holds the whole rule: the shapes above the line, the colours below it, and the word for what to do with them.
- Light background: you may tap only the shapes and colours in the hub.
- Dark background: you may tap anything except those.
An object counts if either its shape or its colour is shown. Wrong taps cost points; glowing tokens are always safe. Rings inside a piece show how many more times it will break; the gaps in each ring show how many pieces it breaks into.
Warning, and grace
The set that is about to arrive appears outside the hub a few seconds early, the rim drains as the change approaches, and a large faint globe empties in the middle of the board for the last two seconds. For a moment after any change, a tap that would have been right just before it is forgiven: it reads just missed and costs nothing. The rules start calm and tighten as you climb.
The background colour is the play mode: zoom out, warm or cool only, greyscale, twinkle, glitch. Modes change how the board looks and moves. They never change what is legal to tap.
Levels and gates
Every level has a gate. The strip under the clock shows each shape and colour the level has unlocked and how many of each you still owe; only correct pops count. Open the gate and the next level brings exactly one new thing. Your place is saved, so Play picks up where you stopped.
- Chains: every ten right taps in a row is celebrated, and the chain multiplies your points.
- Rush pieces (from level 6): a piece arrives inside a spinning rainbow ring. Tap it in time and, if it is allowed, it pops with every piece it would have broken into.
- SLASH (from level 16): tap a legal piece and, without lifting, drag a line to another legal piece. Everything the line crosses is cleared.
- Ranks: every level carries a mineral, from feldspar, the most common on Earth, to kyawthuite, of which one specimen exists. Each new rank comes with one true fact about its stone.

Made for every age
The first run is designed for people who are new to touchscreens. The two-minute lesson has no clock and no score, and it stays on the front page for whenever you want it again. Settings include sound, haptics, colourblind assist, a left-handed layout, reduced motion, flat shapes (no 3D) and the countdown globe.
