Play easy Sudoku online

What makes a Sudoku easy
An easy puzzle starts with many givens, at Sudoku Sagax around 46 of the 81 cells. That lets you determine almost every cell directly, without having to note candidates. It is never about guessing: every digit follows unambiguously from the numbers already placed. That is exactly what makes easy Sudoku so pleasant, you are constantly in the flow and rarely stuck.
The technique: naked and hidden singles
- Naked single. Look at an empty cell and cross out every digit already present in its row, column or block. If exactly one remains, it belongs there.
- Hidden single. Take one digit and one unit (row, column or block). If the digit fits only a single free cell there, its place is found, even if the cell could still hold more digits on paper.
That is all an easy Sudoku needs. Start with the rows, columns and blocks that already hold the most numbers, that is where cells resolve fastest.
