Description

Happy Sudoku is a free-to-play Sudoku game.
Sudoku is a game where you fill in empty squares with numbers. The basic rule is to place the numbers 1 through 9 exactly once in each row, column, and 3x3 block without repetition.
Most questions are relatively simple, so even beginners can enjoy them. Advanced players might find them a bit too easy, but please aim to clear all the questions.
Play Happy Sudoku and get happy!
