Beginning with a comprehensive 'How to Play' section 'Junior Su Doku', the first book published for children and beginners, contains over 120 puzzles using numbers, letters and shapes.
The book opens with some very easy 4 x 4 grids before gently increasing in difficulty to the more complex 6 x 6 and finally to the well known 9 x 9 puzzles. (Solutions provided!)
Just try stopping at one...
