Wagiri is a Nikoli puzzle genre; it is a variant of Gokigen-naname.
- Draw a diagonal line on each square cell indicated on the grid, from one corner to the opposite one.
- If a cell is marked with a ‘輪’ symbol, it must be part of a loop.
- If a cell is marked with a ‘切’ symbol, it must not be part of a loop.
- If a vertex is clued by a number, the number of lines coming from that vertex will be precisely that number.
