Prove Your Puzzle Solver Qualities

Also known as Number Place, Japanese Sudoku ("single-digit") games are a worldwide phenomenon. Although these types of number puzzles were featured in French newspapers as far back as the 19th century, they've gone seriously viral in our more modern age thanks to the Japanese puzzle company who, in the 1960s, created the form the world over knows and loves today. This is because it offers the ultimate test of logic based on the most simple set of rules imaginable: fill a 9x9 grid made up of nine grids of 3x3 boxes. In each mini-grid, fill in the digits 1-9 so that there is only one in each box – and so that each appears in its total row and line of the total bigger grid only once. (If that doesn't sound simple, just open a game and you'll immediately see this for yourself.) You'll get a few numbers to get started, each combination creating a totally new game – which means endless gameplay opportunities!

Web Sudoku is even better than paper Sudoku. When you play Sudoku online, you don't have to keep track of the boxes or do the messy pen or pencil work yourself – scratching out and rewriting as your guesses and number placements evolve. You can focus on the pure gameplay, the fun mental exercise of these Sudoku puzzles. Hoorah for the Age of Computers!

Plus, our free Sudoku games often come with themes, like Sunset Sudoku, Sudoku Hawaii, or Sushi Sudoku, for a new layer of fun to go with the brain-bending puzzles you love. The game can even take a totally different shape all together, literally, in games like Bermuda Triangles. Start exploring and flex that mental muscle!
