One Sudoku offers a variety of puzzle types. In this guide you will learn how to solve all these Sudokus.
Classic Sudokus with evenly shaped boxes available in different sizes.
A playing field with oddly shaped boxes and other mean things.
The boxes have a stair-step shape. This provides an interesting challenge.
In this variant, the result and the operator of an arithmetic problem are given as solution aids.
Additional windows with the same rules as regular boxes to help solve the Sudoku.
The boxes of these Sudokus feature geometrical patterns.
To help solve this variant, there are markings between the cells that symbolise their relationship.
Instead of given numbers, a cell is marked to be greater or less than the neighbouring cells.
Instead of given numbers, only the sum for a random group of cells is shown.
Two diagonals on the playing field will help you solve these Sudokus.
Some marked cells only allow even or odd numbers.
