I had this puzzle for some time now. It is a variant of Sumo (Gattai-13).
Grids 1, 3, 11 & 13 are Sudoku-X
Grids 2, 6, 8 & 12 are Windoku
Grids 4, 5, 9 & 10 are Asterisk Sudoku
Grid 7 is a Clover-X (Asterisk Windoku X)
It shouldn't need more than doubles to solve.
I will be posting the solution on Aug 29th 2011 (bank holiday in England)
