Rules of 'Toroidal Sudoku'

Place numbers in the grid such that each row, column and thick-outlined region contain the numbers 1 to 9. Some of the outlined regions will wrap between the top and bottom edges, and/or the left and right edges of the grid.

This is an extended version of the Irregular Sudoku.

Its quite a crazy sudoku variation due to the difficulty of some of the grids, and also due to the confusion of the regions.

The 8x8 grids are very popular.
