The observant amongst you may have noticed that there is now a total of 12 puzzle magazines linked to from the menu and on the homepage.
This is because the latest magazine has just been added, which is called the binary puzzle magazine. And that's because it contains 52 binary puzzles, one a week
If you've not come across the puzzle before, then you have to fill the grid with 0's and 1's such that each number occurs the same number of times in each row and column, the same digit does not appear in more than two consecutive cells, and that the set of rows and columns is unique.
