Sudoku Brainzy: fun, brainy

Sudoku Zen is a calm, beautiful Sudoku that helps you get better. Every puzzle has exactly one solution and can be solved by logic alone, with no guessing. A COACH, NOT JUST A HINT BUTTON Stuck? Tap the bulb. The first tap points you to the right area. The next names the technique and draws the logic on the board. Only then does it place the digit. Hints check your mistakes first, so you learn what went wrong. DAILY CHALLENGE A new puzzle every day, the same for everyone, even offline. Difficulty rises through the week. Each Daily you finish reveals a tile of the month's mosaic, and your streak keeps you coming back, with rest days to protect it. PUZZLES THAT FIT YOU Six levels from Beginner to Master, graded by the techniques each puzzle needs. "Just right" picks the level that matches your skill rating, which grows as you play. SUDOKU ACADEMY 30 short lessons, from the basics to X-Wing and Swordfish. Each one shows the technique on a live board, then lets you practise it on a real puzzle. 10 VARIANTS Killer, Thermo, Arrow, Kropki, Jigsaw, Diagonal, Hyper, Even–Odd, and Mini 4×4 and 6×6 grids. BRING PUZZLES FROM PAPER Scan a Sudoku from a newspaper or book with your camera, check the digits, and play it here. Or type one in, or paste a puzzle code from a friend.
