I will be posting all my Kazagurumas in this thread from now on. The subgrids may have sudoku variants and will be clearly indicated. The 5 subgrids may not have identical constraints so please read each puzzle's description before solving. The description will also hopefully give a rough idea of the difficulty.

Some posted puzzles may be beyond the scope of the human solving capabilities, this will also be indicated in the puzzle's description.


Previous postings include:
Bank Holiday 0808 Kazaguruma Special (Several puzzles)
WC2010 dedicated puzzles: Puzzle01, Puzzle2 & Puzzle3

Enjoy,

This puzzle has 4 windoku satellite grids (no X diagonals)
The central grid has Disjoint groups (DG) & X diagonals. The DGs are not visible from the graphic :cry:
The puzzle should be solvable within SSTS
