What a Su-Pu records
A Scorecard is generated for every completed game: difficulty, time, mistakes, hints, steps, bonuses, and personal Puzzle Score. A Su-Pu (数谱) is different. It preserves the move sequence of an eligible personal solve — placements, candidate notes, pauses, corrections, hints, and the turning point that opened the grid — so the solve can be replayed and studied.
Official competition attempts create protected competition records and verified Ranking Points. Those are separate from public personal Su-Pu and never appear in this library — see Compete and Rules & Scoring.
The loop is simple: find a technique, watch a real solve, understand the turning point, then practise it. Learn the strategy, practise the pack, or study a related lesson.
