Film L(2,1) D(25,7,0,0,0,0)

Moderate

Similar to the regular 9 by 9 Sudoku but the squares have lumps in the top and bottom. The problem wraps top to bottom but not side to side so the overall geometry is a cylinder.

People L(2,1) D(22,12,0,0,0,0)

Moderate

The shapes have “lumps” on each side to become quite irregular. They look to me like little people. This problem wraps top to bottom and side to side so the overall geometry is like a doughnut (torus).

Sudoku 9X9 L(1,1) D(28,5,0,0,0,0)

Easy

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(2,4) D(19,13,1,1,1,0)

V Difficult

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).

Tred 02 L(2,1) D(29,5,0,0,0,0)

Moderate

Tredoku 3 dimensional problem 02 with 8 faces, 6 rows and 9 columns
