Sandwich Sudoku Puzzle Book

If you're reading this page, the chances are that you've heard of the fun sudoku variant sandwich sudoku, which you may also know as between-1-and-9-sudoku.

If you're new to the variant, then the rules are simple: in addition to the standard sudoku rule of placing 1-9 once in each region, you must also obey the totals around the edge of the grid that tell you the sum of the digits placed between the 1-9 in that region (or 1-6 in the smaller 6x6 sandwich sudoku puzzles).

This book contains 50 6x6 sandwich sudokus and 50 9x9 puzzles. All can be solved with logic alone and have a single solution, but that doesn't mean they aren't tricky to solve! If you're new to the puzzle type we suggest you warm-up with some 6x6 puzzles, or if you're an experienced solver you might want to keep those for when you have a few minutes spare and want a quick challenge.

Here are the rules of sandwich sudoku explained in a video:
