Trio Sudoku
The easiest Sudoku variation where cells are divided into three independent digit groups
Trio Sudoku is the easiest Sudoku variation, making it perfect for kids and beginners. In Trio Sudoku, similar to Even-Odd Sudoku, the grid is divided into three parts, and each part can be solved independently. This means the difficulty level is roughly one-third of standard Classic Sudoku. Kids love to solve this Sudoku type, and it is one of the best Sudoku types to introduce children to Sudoku variations. I have created many Trio Sudoku puzzles not only for kids but also some Trio Sudoku variations for experienced Sudoku players. This collection includes standard Trio Sudoku puzzles along with Touchy Trio Sudoku, XV Trio Sudoku, Non-Consecutive Trio Sudoku, UnTouch Trio Sudoku, and Disjoint Groups Trio Sudoku variations. This page contains links to all Trio Sudoku puzzles and their variations published on this website.
