困难 大于数独
单元格之间的不等号显示哪个更大。没有已知数字——所有放置仅从符号推断。
困难 大于数独。长不等式链、跨链宫交互，以及很少或没有已知数字——完整的候选数追踪至关重要。

困难 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| 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. | 初级 |
| Chain Inequality — Maximums | In the chain A > B > C > D, also bound from above: A ≤ 9, B ≤ 8, C ≤ 7, D ≤ 6. | 初级 |
| Inequality Propagation | After placing a digit, check all inequality arrows from that cell and eliminate impossible values from its neighbours. | 中级 |
| Forced Single via Range | When an inequality chain reduces a cell's valid range to a single digit, place it directly. | 中级 |

在困难需要掌握的技巧
- Hidden Pairs technique — Bound propagation removes middle candidates invisibly; recount each box after walking the chains, because hard greater-than grids hide pairs behind out-of-date ranges.
- X翼技巧 — Extreme digits have the fewest chain-legal positions — 1 can never sit above a > sign, 9 never below — so X-Wings on 1 and 9 are the natural hard-mode tools.

相关变体
黑白点数独
Refines your adjacent-cell reasoning with exact relationships — difference of 1 and ratio of 2 instead of plain order.
XV数独
Adjacent pairs constrained by sums rather than order, with a negative constraint on every unmarked edge.
奇数 / 偶数数独
Another value-property variant: parity shading halves candidates the way your inequality chains bound them.
