In a previous post I already mentioned Puzzle Japan where I found my favorite Slither Link Puzzle books.
At Puzzle Japan they have much more number puzzles and if may say so the are all Sudoku look-a-likes. One of my favorite puzzle right now is Hitori. The rules are simple:
1. Numbers never appear more than once in each row or column.
2. Painted cells are never adjacent in a row or a column.
3. Empty cells create a single continuous area, undivided by painted cells.
And the best thing is you can also solve Hitori puzzles at the Puzzle Japan website. Happy Puzzling!
