Noughts & Crosses Puzzles
by Clarity Media
Single player fun - Place noughts (O) and crosses (X) in each row and column of the grid such that there are the same number of noughts and crosses in each of the rows and columns in the grid.
The same symbol cannot occur in more than two consecutive squares either horizontally or vertically. This means that OOO is invalid, whilst OOX is fine.
The book contains:
30 Easy Puzzles (6x6 grids)
35 Medium Puzzles (8x8 grids)
15 Hard Puzzles (10x10 grids)
20 Very Hard Puzzles (10x10 grids, requiring an extra solving rule explained in the book!)
All puzzles can be solved logically and you’ll never need to guess to make progress in solving these fun puzzles.
Additional rules can be found for the very hard puzzles.
Good luck & happy solving!
