The cube takes shape
Sudoku folded onto six faces that share their edges. A row on the front keeps going on the right face, and a corner digit counts three times.
Roadmap
Built all faces at the same time

The cube you can hear
Sound effects in two packs, Calm or Arcade, and cells that light up when you finish a number: Burst, Teleport, Neon, Ripple or Gold. Both sit in Styling's new Play tab, and a speaker beside the Styling button mutes the sound in one tap.

Eight modes to earn
Beat the Clock, Speed Run, Tug of War, the Lightning Round, Survival, Missions, Roulette and Endless are out of testing. Each one opens as you play, at a level or with a trophy, and Game modes on the home screen shows them all.
- Oct 2026Milestonev1.6
Missions
Each cube comes with one to four missions to keep, like starting with a 7 or never using a pencil mark. A mission glows amber before a move would break it, a win pays double XP, and the Daily Mission is the same for everyone.
- Oct 2026Milestonev1.6
Roulette
The cube turns itself every minute, or as often as you choose, and you solve what it shows. Drag to peek and it swings back; your time is your score.
- Oct 2026Milestonev1.6
Tifinagh
Classic sudoku with its nine digits drawn as letters of the Amazigh alphabet of Morocco. You solve by shape, not by counting, and a legend of the nine letters helps while you learn them.

One Face
Classic 9×9 sudoku on the front face of the cube, the other five left blank, and a cube that only tilts. A game takes minutes, not an evening: 2,000 puzzles in the app and 4,000 more to download.

Playable on a PC
