TL;DR

500 道已評分的謎題，依 SE 區間整理 — 從只需唯一數的暖身題到怪物級的鏈式難題。

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

這個區間還有 27 題。

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

這個區間還有 57 題。

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

這個區間還有 92 題。

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

這個區間還有 92 題。

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

這個區間還有 92 題。

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

這個區間還有 81 題。

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.

這個區間還有 3 題。
