Description
Colossal Sudoku is a puzzle book you can actually read from the recliner. Huge numbers and clean grids mean less eye strain and more time enjoying the solve.
Extra-large 36-point type, a pair of puzzles on each page, large 8.5″ x 11″ format and an answer key for all 200 puzzles, plus sudoku tips and tricks to get you started.
Every puzzle in this book is rated Hard. At the Hard level, the easy entries run out quickly. Patience and careful pencil marks are your best friends as you hunt for the one cell that unlocks the rest of the grid.
FatMunkey’s tip for this book: If two cells in a box share the same three candidates with a third cell, you’ve found a ‘naked triple.’ Those three digits belong to those three cells.
