Welcome to this great selection of 100 brand new binary puzzles. They are all played on a 10x10 size grid. 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 five 0's and five 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 0101010101 then no other row in the column can contain exactly the same ten-digit sequence. Similarly if a column contained 0101010101 then no other column could contain that same sequence. That's all there is to it
