Rubik's Cube Timer
Mystery Timer is a free online Rubik's Cube timer that keeps every solve time hidden until your session ends, so you can practise without chasing the clock. Pick 5, 12, 50 or 100 solves, use WCA-style random-state scrambles with optional 15-second inspection, then reveal your best single, mean and averages at the finish.
An honest test of your cubing ability: nothing is shown while you solve. Your times and averages are revealed only after the final solve of the session.

Solve blind
Space (or a tap) starts and stops each solve. Times stay hidden until the end.
