How it plays

Built around fast reads and satisfying solves.

Greater Than

Fill every row, column, and 3x3 block with the numbers 1 through 9. Adjacent cells inside a block must obey the greater-than or less-than symbol on their shared line.

Division

Use normal Sudoku rows, columns, and blocks, then follow division clues between neighbors. A divides B means A evenly divides B, and some greater-than clues can appear too.

Circles

The circular board has 4 rings and 8 slices. Place 1 through 8 exactly once in each ring, each slice, and the directly opposite slice group.
