解題技巧：專家 等級
| 技巧 | 描述 | 等級 |
|---|---|---|
| Chain Inequality — Minimums | Link inequalities in a chain: if A > B > C, then A ≥ 3, B ≥ 2, C ≥ 1. Use these minimums to prune candidates immediately. | 初學者 |
| Chain Inequality — Maximums | In the chain A > B > C > D, also bound from above: A ≤ 9, B ≤ 8, C ≤ 7, D ≤ 6. | 初學者 |
| Inequality Propagation | After placing a digit, check all inequality arrows from that cell and eliminate impossible values from its neighbours. | 中級 |
| Forced Single via Range | When an inequality chain reduces a cell's valid range to a single digit, place it directly. | 中級 |
在 專家 需要掌握的技巧
- X-Wing 技巧 — Expert grids interleave chains so no cell bounds to a single digit — fish on 1 and 9 first, since the inequality lattice constrains the extremes most brutally.
- Swordfish technique — Long inequality chains confine middle digits to matching columns row after row; expert greater-than endgames are usually broken by a Swordfish on 4, 5, or 6.

Kropki數獨
Refines your adjacent-cell reasoning with exact relationships — difference of 1 and ratio of 2 instead of plain order.
XV 數獨
Adjacent pairs constrained by sums rather than order, with a negative constraint on every unmarked edge.
奇數 / 偶數數獨
Another value-property variant: parity shading halves candidates the way your inequality chains bound them.
