Medium Sudoku
Medium is the step where sudoku starts to feel like a real puzzle. Each Medium puzzle on Kodiak Sudoku starts with about 33 givens, so scanning gets you partway and then you need to think a little harder.
This is where most players start writing notes (the small candidate digits in each cell) and looking for hidden singles and pointing pairs.
What to expect
- About 33 givens.
- Scanning stalls partway through; notes help.
- Hidden singles do most of the work, with the odd pointing pair.
Techniques you'll use
Tips
- Scan until you're stuck, then fill in notes for the most crowded box.
- After every digit you place, check its row, column and box for a new single.
- Keep notes current: erase a digit from its peers as soon as you place it.
