Tap to move
Tap a column to lift its top tile, then tap where it goes. It lands on an empty column or on a tile of its own colour — nowhere else.
Every mechanic
Small rules, deep boards
One tap moves one tile. Everything interesting in the game comes out of what that single rule makes possible.
How you play
The moves you start with, and the three power-ups that open up as you go.
Lock a colour
Four matching tiles in one column seal it shut. Locked columns stay out of the way for the rest of the level.
Rainbow wild
The rainbow tile counts as any colour, so it can close a set you were one tile short of finishing.
Undo, from level 7
Step a move back when you spot the better line a second too late.
Hint, from level 12
Points out a move that leads somewhere, for when the board stops making sense.
Swap, from level 15
Trade the tile in your hand for a different one, so a single awkward colour cannot stall the whole board.

Ninety free, then uncapped
Ninety levels cost nothing. The one-time Pro unlock removes the cap, and the generator has no last level to reach.
How it is built
The parts you do not see, and the ones left out on purpose.
Never an impossible board
Levels are generated by scrambling a solved board backwards, so every single one has a way through. Difficulty comes from finding it, not from luck.
Relax Mode
Removes the move budget completely. The same levels, without a fail state waiting at the end of them.
Works offline
Levels are generated on your device rather than fetched, so the game plays the same on a plane as it does at home.
Nothing collected
No account to create, no analytics, and no advertising identifiers. Progress is stored on your iPhone — sign in to Game Center and Apple keeps a saved copy so it follows you to another device.
Ninety free, then uncapped
Ninety levels cost nothing. The one-time Pro unlock removes the cap, and the generator has no last level to reach.
Built for iPhone
A native SwiftUI app for iOS 17 and later, with haptics on every move and VoiceOver labels on the board.
