Normal sudoku rules apply; i.e. the digits 1 to 9 need to be placed, once each, in every row, column, and 3x3 box.

This grid is set on a torus, and only has 100 cells. This means that row 1 and row 11 are in fact the same row. The same is true of column 1 and column 11. Within the grid are 10- 3x3 boxes that must be found. This means that there are 10 cells in the grid that contain no digit. (Blank cells use a zero to solve uniquely)

Cells separated by a knight's move (in chess) cannot contain the same digit.

Digits along an arrow must sum to the digit in that arrow’s circle.

Digits in a cage must sum to the number in the top left corner of that cage.

Cells separated by a white dot must be consecutive.

Cells separated by an X must sum to 10.
