Diamond L(2,4) D(24,14,2,2,1,0)
Here the shapes are pushed over to become diamonds. This wraps side to side but not top to bottom.
Jigsaw L(2,4) D(25,13,1,1,1,0)
As regular 9 by 9 but the normal 3X3 boxes are irregular shapes
Sudoku 9X9 L(1,1) D(27,7,0,0,0,0)
This is the standard geometry that is usually seen. Characters must not repeat in rows or columns or in any of the 3 by 3 boxes that are outlined.
Toroid H L(3,4) D(19,20,2,2,2,0)
The normal 3X3 boxes are replaced by horizontal stripes (helices) which wrap around the problem. These stripes join the left side to the right side and the top to the bottom so that the overall geometry is a doughnut (torus).
Use of the “diabolical” character set makes this problem even harder.
Tred 04 L(2,1) D(38,4,0,0,0,0)
Tredoku 3 dimensional problem 04 with 10 faces, 6 rows and 12 columns
