You shuffle.
The AI sweats.
Cube Challenge is a phone game: scramble a 3×3, give the AI a few seconds, and see who finishes. You can also photograph a real cube and follow the solve one move at a time.
Next opponent is never a surprise
Three brains. One cube.
They rotate so you meet each one every three rounds, and never the same AI twice in a row. The play screen shows who is coming.
Lazy
Slow turns. Sometimes it nods off.
Normal
Quick, until a butterfly flies past.
Genius
Barely blinks. The long timer is its friend.
A round, in three beats
- 01
Shuffle
Twist the 3D cube, or let the game scramble it. Swipe a layer or tap one of the twelve moves.
- 02
Set the clock
Pick 5, 10, 20 or 30 seconds, or any time from 3 to 60. Short clocks favour you.
- 03
Challenge
The AI solves with a real two-phase cube solver. If the timer dies first, you win.
Point it at a real cube
Scan is optional. Show one face at a time, or type the stickers yourself. Colors are read on the phone and are not uploaded. If the camera stays off, the race still works.
Camera permission is asked only when you open the scan.
