Sudoku that stays quiet.
No drop shadows, no fireworks, no banners jumping at you. Paper-coloured background, numbers, and a few lines. A game lasts five to fifteen minutes and nothing interrupts it.
• Six difficulty levels — from your first grid to genuinely hard ones
• 4×4, 6×6 and 9×9
• A daily puzzle everyone in the world solves on the same day, with a streak worth keeping
• Hints that tell you why, not just where
• Pencil marks, undo, and an error check you can switch off
• Statistics per level — best time, average, completion rate
• 19 languages
No full-screen ads.
Nothing covers the screen between games. The banner sits where it cannot hide the board. You only watch an ad when you choose to — to refill lives or take an extra hint.
Tablets are not a stretched phone.
Turn a tablet sideways and the timer, mistakes, tools and number pad move into their own column beside the board. The two layouts were built separately.
No account.
There is nothing to sign up for. Your game in progress, statistics and settings stay on the device, and everything works with no connection.
Every puzzle is checked for exactly one solution before it reaches you. And a finished grid is judged by the rules of sudoku, not by comparing it to a stored answer — if you solved it your own way, you solved it.

New rule: Killer. The digits in each dotted cage add up to the small number in its corner. Start from the Killer tab at the bottom.
