About Sudoku - Number Games
Sudoku - Number Games is the classic number-placement puzzle. The board holds 81 cells, arranged as nine smaller squares of three by three. Your task is to complete it so that every row across, every column down and every one of the nine squares contains the numbers 1 to 9, with no number appearing twice in any of them. Each number you place rules that number out for the rest of its row, its column and its square.
The puzzle is pitched as practice for attention, memory and logic. Levels grow tougher as you move up, but nothing is closed off behind you: earlier, easier levels stay open, so you can step back to a gentler puzzle whenever a hard one stalls. That makes it simple to warm up on an easy board before tackling a harder grid, and to return to the tough one once the elimination habits feel natural again.

How to play Sudoku - Number Games
Objective
Fill every empty cell so each row, each column and each 3x3 square holds the numbers 1 to 9 exactly once, then advance to harder levels.
Getting started
- Look at the board's structure first: nine rows, nine columns and nine 3x3 squares, each of which must end up holding 1 to 9.
- Pick a 3x3 square that already has many numbers in it and work out which of 1 to 9 it is still missing.
- For each missing number, check the rows and columns crossing that square to see which empty cells could still take it.
- Place a number only when exactly one cell is left for it, then recheck nearby squares, since each placement removes options there.
- If a level becomes too hard, return to an earlier, easier level and build up again from there.
Tips
- Every placement removes that number from its row, column and square, so after each entry scan those three areas for a cell with one option left.
- Rows, columns and squares obey the same rule, so when a square stalls, switch your attention to a nearly full row or column instead.
- A row or column with only one or two empty cells is the quickest win, because the missing numbers can be read off the ones already there.
- Use the easier earlier levels as warm-ups; they are always available, and the same elimination steps carry over to the harder grids.
