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(21,10,0,0,0,0)

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 9X9X L(1,1) D(22,12,0,0,0,0)

Easy

As regular 9 by 9 but must also have unique characters in each diagonal, highlighted.

Toroid V L(2,1) D(20,13,0,0,0,0)

Moderate

The normal 3X3 boxes are replaced by vertical 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 04 L(2,1) D(38,5,0,0,0,0)

Moderate

Tredoku 3 dimensional problem 04 with 10 faces, 6 rows and 12 columns
