3×3 (and OH, BLD) and 2×2 scrambles are random-state: a random legal cube position solved with a Kociemba two-phase solver (3×3) or an exhaustive BFS table (2×2), like csTimer. Until the solver finishes loading, and for other puzzles, scrambles are WCA-notation random-move sequences (no same-face repeats, no three moves on one axis): 4×4–7×7, Pyraminx, Skewb, Megaminx, Clock, and shape-checked Square-1. Times are truncated to 0.01 s; averages trim the top and bottom 5% (ao5 and ao12 drop one each).
Each session keeps its own event and stats. Click a row's name to rename it.
