### Logidoku

Logidoku is a Sudoku variant created in 2005 by Josie Faulkner. The usual rules apply, where each number can only appear once in each row, column and 3x3 block, but there are two more rules:

1. The marked irregular areas can only contain each number once, and

2. The long diagonals can only contain each number once.

These five rules mean that a standard 9x9 grid can contain a puzzle that has far fewer clues than a normal sudoku. The puzzle could be represented as a killer sudoku, where each of the cages has to add up to 45.

Josie has hand-crafted a number of these puzzles, which are available in the sudokuworld Yahoo! group.
