Tred 01 L(2,1) D(26,5,0,0,0,0)

Moderate

Tredoku 3 dimensional problem 01 with 7 faces, 6 rows and 6 columns

Diamond L(2,1) D(21,9,0,0,0,0)

Moderate

Here the shapes are pushed over to become diamonds. This wraps side to side but not top to bottom.

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 9X9 L(1,2) D(28,10,1,0,0,0)

Gentle

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.

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

Tred 02 L(2,1) D(27,6,0,0,0,0)

Moderate

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

Film L(2,4) D(23,23,6,6,3,0)

V Difficult

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(2,2) D(20,18,2,0,0,0)

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).

Toroid V L(2,4) D(23,15,3,3,2,0)

V Difficult

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).
