The Book of Binary Puzzles 12x12 Volume 3

Welcome to this great selection of 100 brand new 12x12 binary puzzles. Here are the rules of the game: - Place 1's and 0's in each row and column of the grid such that there are exactly six 0's and six 1's in each row and column - The same digit cannot occur in more than two consecutive cells. Thus 000 is invalid, whilst 001 is fine - A row cannot repeat in the grid, and neither can a column. For instance if one complete row contains 010101010101 then no other row in the puzzle can contain exactly the same twelve-digit sequence. Similarly if a column contained 010101010101 then no other column could contain that same sequence. All puzzles are complete with solutions towards the back of the book and printed on very high quality paper. For other puzzle books, visit
