Calcudoku Magazine added...

Today a magazine has been added that contains 100 calcudoku puzzles.

These are all 6x6 in size and the puzzles get harder as you progress through the magazine.

If you've not come across calcudoku puzzles before then it is worth noting that they are known under various names.

The most common name is kenken, and this is also called kendoku. However one of those is a trademark and the other might be; other names for the puzzle include hitoshii, square wisdom, mathdoku, sumdoku and probably more besides.

However whatever the name, it is a fun variant on sudoku and then on killer sudoku
