简单 箭头数独
沿每个箭头的数字之和必须等于圆圈中的数字。箭头和经典数独规则结合，构成纯逻辑。
新手 箭头数独? 从短箭头开始——一个单元格的尾意味着尾单元格等于圆圈。从约束最多的箭头向外工作。

在简单需要掌握的技巧
- Last Possible Number technique — A two-cell arrow under a small circle leaves its shaft cells with two or three candidates at most — one row or box check usually finishes them.
- Last Remaining Cell technique — Circle cells must hold large digits (at least the sum of their shaft's minimum), so when a box needs its 8 or 9 placed, the arrow circle is frequently the only legal cell.
- 数独中的笔记 — Note every shaft combination beside the arrow, not generic 1–9 marks — a 3-cell shaft summing into a 6 circle is only ever {1,2,3} in some order.
