Practice against the clock

Timer with scramble and 3D cube

As soon as you arrive, a scramble is generated automatically: the 2D cube and the 3D cube are set up the same way, so you can inspect it before you start. Hold down the spacebar (or tap the screen) to arm the timer; release it to start, and press again to stop. Each time is saved together with its scramble, and a new one arrives instantly — press “Re-Scramble” if you want another one without solving the current one.

⏳Cube colors: standard competition convention (U white, D yellow, F green, B blue, R red, L orange) — different from the teaching scheme used in Notation and Learn, so scrambles read the same as on your physical cube.

💾Your progress is saved on this device, but you can export it as text and keep it wherever you like (or move it to another computer) with “Save progress” / “Load progress”. Turn on Competition mode to simulate a real WCA-style round: your Ao5 and Ao12 series show up separately, with the best and worst time in each one marked.
