Masyu以是一种画线形成回路的谜题,首次发表于日本谜题杂志《パズル通信ニコリ》第90期(2000年春季刊),是第84期(1999年4月刊)“珍珠首饰”(真珠の首飾り)的改良版本。

规则

用横向或纵向的线连接方格,并经过所有黑圈与白圈格,形成回路。白圈格必须笔直通过,且在其前一格和/或后一格拐弯;经过黑圈格要直角转折,且前后必须直行通过其周围方格,直到第二个方格才可转折。

① Draw a single closed loop which does not cross or touch itself.
② The sections of the loop run horizontally or vertically between the center points of orthogonally adjacent cells.
③ The loop must visit all cells with a white or a black circle but not necessarily all other cells.
④ In a cell with a black circle the loop must turn by 90° and must travel straight through the previous and next cell.
⑤ In a cell with a white circle the loop must travel straight through and must turn by 90° on the previous or the next cell.

另有一种被称为双面珍珠的题目,把所有白珍珠换成黑珍珠,所有黑珍珠换成白珍珠之后还是合格的题目。
