[Inequality Sudoku]
Inequality Sudoku is a Sudoku game where the size of adjacent squares is indicated by a inequality sign. Like normal Sudoku, each vertical and horizontal column contains numbers 1 to 9. High-level problems may be difficult until you get used to them, but we only offer Sudoku puzzles that can be solved logically, so please try to be persistent.

[Cross Sudoku]
Normal Sudoku is to fill in the numbers 1 to 9 in three patterns: [vertical], [horizontal], and [within thick frame].
In addition to this, Cross Sudoku adds the element of [diagonal].
Numbers 1 to 9 are also entered in the colored diagonal squares.
Enjoy Sudoku with a difference!

[Jigsaw Sudoku]
Jigsaw Sudoku is similar to regular Sudoku, where you fill in the numbers 1 to 9 using three patterns: [vertical], [horizontal], and [within a thick frame].
However, the range of [bold frame] changes depending on the problem, like a jigsaw puzzle.
Of course, each [bold frame] will contain a number from 1 to 9.
The high level of Jigsaw Sudoku is quite difficult...!

Cross Jigsaw Sudoku is a Sudoku that has the characteristics of both Cross Sudoku and Jigsaw Sudoku.
Like Cross Sudoku, numbers 1 to 9 are included in the diagonal, and like Jigsaw Sudoku, the range of thick frames that contain numbers 1 to 9 changes depending on the problem.
