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)
In addition, normal sudoku rules apply; i.e. the digits 1 to 9 need to be placed, once each, in every row, column, and 3x3 box.
Digits in a cage must sum to the number in the top left corner of that cage. Digits can not repeat inside a cage.
The gray lines in the grid are palindrome lines; meaning that digits along the lines read the same forwards and backwards.
Solution code: digits along the bottom gray line. (use zero for black cells if needed.)
