TL;DR

SE 밴드별로 정리된 채점 퍼즐 500개 — 싱글만으로 푸는 워밍업부터 몬스터급 체인까지.

SE grade 1 — The gentlest puzzles. Solvable end-to-end by spotting naked and hidden singles — no candidate bookkeeping required.

이 밴드에 27개 더 있어요.

SE grade 2 — Easy puzzles that still resolve through singles, but you may need to scan more carefully before the next placement appears.

이 밴드에 57개 더 있어요.

SE grade 3 — Intermediate. Pairs and locked candidates (pointing/claiming) start to matter — you eliminate candidates rather than place values directly.

이 밴드에 92개 더 있어요.

SE grade 5 — Hard. Basic fish (X-Wing) and consistent candidate elimination across rows and columns become the bread and butter.

이 밴드에 92개 더 있어요.

SE grade 7 — Expert. Wings (XY-Wing) and larger fish (Swordfish) appear; progress often depends on chaining one elimination into the next.

이 밴드에 92개 더 있어요.

SE grade 8 — Diabolical. Simple techniques run dry early; you lean on forcing chains and careful candidate logic to break the puzzle open.

이 밴드에 81개 더 있어요.

SE grade 11 — Monster territory. These puzzles have no easy entry point and demand long forcing chains end to end — the home of AI Escargot, Golden Nugget and Platinum Blonde.
