Play Masyu Online

Masyu is a rarely seen logic puzzle from Japan that is great fun and is sure to have you scratching your head!

The instructions are as follows: the grid contains white and grey circles. You must create a single continuous loop passing through all the cells that are circled on the grid and some other cells based on the rules. The loop must go through each cell it passes through in its center and leave the cell from a different side. Cells containing circles have special significance:

White circles denote that the loop must go straight through that cell without turning in it, however in the next and/or previous cell to that containing the white circle the loop must turn (all turns are 90 degrees). Black cells in contrast denote that the loop must turn inside that cell, but the loop must travel through both the previous and next cells without turning.
