These free Sudoku games help train memory, math ability, and analytical thinking ability. "Sudoku" is a number puzzle game that has become very popular in recent years. The game above includes thousands of puzzles, from easy to super hard. The controls are below the puzzle. Enjoy!

HOW TO PLAY. The goal is to fill the 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9, only one time each. The puzzle setter automatically displays a partially completed grid.

Click the black down arrow to select the difficulty of the game. You can pick "very easy", "easy", "medium", "hard", "very hard". Now you're ready to play! Click the right arrow if you want to load a new game. Click the round gear button to show the solution. Clicking the small clock pauses the game, and if you want to see all the instructions, simply click the question mark button. Have fun!
