Trainer how-to

The trainer drills the full CFOP library — Cross 22, F2L 41, OLL 57, PLL 21 — plus decks for the beginner method, Roux, ZZ, Petrus, blindfolded and one-handed (365 cases in all), the way you actually turn, timing each rep by move completion rather than cube state. That’s what lets you repeat an algorithm many times without re-scrambling between reps.

1. Pick a set

Choose a method, then a phase (say OLL) and a subset — a single case, a group, or the whole set. Every case is open to every account.

2. Choose your algorithm

Each case shows an exact generated diagram — PLL arrows are computed from the real permutation, not drawn by hand — with one or more algorithms. Star the one you want to learn; the trainer drills your starred algorithm and remembers it per case.

3. Drill

The app sets up the case and starts watching. Execute the algorithm on your cube; the rep is timed from your first turn to the move that completes the case, then it immediately queues the next rep. Do twenty in a row without touching a scramble.

4. Read speed and accuracy

Every rep gets a time, and a wrong turn counts as a miss — so accuracy sits right next to your rep times. A fast average with shaky accuracy tells you the alg isn’t in muscle memory yet. Stats are kept per case and per algorithm variant; see training stats.
