240 Multi Sudoku in 12 Variants

240 Multi Sudoku in 12 Variants is all about overlapping grids. Each book holds 240 puzzles across twelve merged layouts, including Samurai, Sohei, Butterfly and Flower, where Sudoku grids share boxes and you have to think across the whole puzzle.

This series gives you the most choice of level. Five books each keep to a single difficulty: Easy, Medium, Hard, Very Hard and Extreme. A sixth, Easy to Extreme, mixes every level in one book. That makes it easy to pick exactly the challenge you want, or to move up one level at a time.

Each layout joins its grids in a different way, and the shared boxes are where the logic gets interesting: a number placed in one grid can unlock a move in another. Moving between twelve layouts keeps every session fresh.

The books are printed at 8.5 x 11 inches. If you'd prefer three rising levels in each book instead of a single level, see 252 Multi Sudoku in 12 Variants. For the toughest single layout, try Hard Core Samurai Sudoku 200.
