玩法说明与常见问题How to play & FAQ
「骑士巡游」怎么玩？How do I play Knight's Tour?
马每次横走两格再竖走一格，或者竖走两格再横走一格。走过的格子不能再走，目标是走满整个棋盘。经典技巧是“沃恩斯多夫规则”：优先跳到下一步可走位置最少的格子，先把边角走掉，最后再回到中间，这样很少会走进死胡同。5×5 棋盘需要从特定的格子出发才有解，可以先从角落试试。A knight moves two squares one way and one square at a right angle. You can't land on a visited square, and the goal is to cover the whole board. The classic trick is Warnsdorff's rule: jump to the square with the fewest onward moves, so the edges and corners get used up early and you rarely get trapped. On 5×5 only some starting squares work — try a corner first.
每个起点都能完成吗？Can every starting square be completed?
6×6、7×7 和 8×8 从任意格子出发都有解；5×5 只有一部分格子（包括四个角和中心）作为起点才能走完。On 6×6, 7×7 and 8×8 every square works as a start; on 5×5 only some squares do, including the four corners and the centre.
提示会直接替我走吗？Does the hint move for me?
第一步提示会帮你选起点；之后提示只会高亮下一步建议的格子，由你自己来跳。The first hint picks a start square for you; after that it only highlights the suggested next square and you make the jump.
