Sudoku - Number Games

Nine squares, nine cells each, and one rule you already know: no repeats in any row, column or square. That's the whole engine behind Sudoku - Number Games, and it's exactly why it's so easy to lose an hour without noticing.

This one's for the player who likes a puzzle that respects their time - no timers screaming at you, no lives running out, just numbers waiting to be placed correctly. If you've ever solved a sudoku in a newspaper and wanted that same feeling without hunting for a pencil, this is your kind of game.

Levels get tougher as you climb, but nothing's locked behind pressure - you can always drop back to an easier stage if a grid is fighting you. It's the kind of steady, brain training loop that rewards patience more than speed.

Plays free right in your browser on desktop, Android or iOS, no download needed. Fair warning: it's landscape-only, so give yourself the wider screen and let your eyes wander the grid.

Fill every row, column and 3x3 square with the numbers 1 to 9, using each number exactly once per row, column and square - no repeats allowed anywhere in those nine cells.

Tap or click a cell, then choose the number you want to place. Work through the easy, obvious cells first before tackling the trickier ones.

Stuck on a level? Back off and replay an earlier, easier one instead of forcing a bad guess - one wrong number can ripple through the whole grid.
