Every variant brings a fresh twist on logic. Master one, then discover another. The grid never gets old.

Classic Sudoku

Diagonal
Each digit, 1 to 9, must appear only once on each of the 2 main diagonal lines.
Thermo
Digits on a Thermo line must increase, starting from the grey circle.
Sandwich
The sum of digits between 1 and 9 in each row must equal to the number to the left of that row. Similarly, the sum of digits between 1 and 9 in each column must equal to the number above that column.
Killer
The sum of the digits in each dotted cage must equal to the number at the top left corner of the cage. Digits cannot repeat in a cage.
XV
Cells separated by X must sum to 10, and cells separated by V must sum to 5. Adjacent cells without X or V don’t have any restrictions.
Kropki
The digits in adjacent cells with Hollow dot must be consecutive and the digits in adjacent cells with solid dot between them have a ratio of 2:1. Adjacent cells with no dots have no restrictions.
Arrow
Digits along the Arrow must sum to the number in the circle at the base of the arrow. Digits along the arrow can repeat.
Jigsaw
Each row, column, and irregular shaped block of 9 cells must have all the digits 1 to 9 only once.
German Whispers
The difference between adjacent digits along a German Whispers Line must be at least 5. **Color: Red**.
Renban
Digits on a Renban line must be distinct consecutive numbers, arranged in any order, for example: 3-6-5-4-7. **Color: Green**.
Skyscraper
