One line. Every number: a puzzle half solved. Portals, arrows, ice and more: a level with special tiles. A fresh puzzle every day: the home screen with a 12-day streak. Race the clock in Endless: a timed run with a combo. Easy on the eyes, day or night: the Midnight theme. Crack a fortune cookie: collected fortunes and path colours.

A daily knot

Everyone gets the same puzzle each day. Solve it to grow your streak.

Twelve worlds

From gentle 5×5 boards to 8×8 snarls with portals, ice, keys and fog.

Endless time attack

Puzzles keep coming. Every solve buys time; clean solves build a combo.

Paper and Midnight

A light and a dark theme, plus path colours to collect from fortune cookies.
