Easy Sudoku for Beginners: 10 Puzzles Worth Starting With
Easy Sudoku for beginners can be solved using only two core techniques: finding Naked Singles and Hidden Singles through elimination. With practice, a true 'easy' 9x9 puzzle should be completable in 10 to 15 minutes without needing advanced strategies. This guide provides a clear, three-stage path from a 4x4 warm-up to your first full-size puzzle, ensuring you build confidence and skill progressively. If you're new to the game, first review our guide on [How to Play Sudoku](/blog/how-to-play-sudoku) for the fundamental rules.
Stage 1: Master the 4x4 Mini-Sudoku
The perfect starting point is a 4x4 Sudoku grid. It uses the numbers 1 to 4 and is divided into 2x2 blocks. This small scale lets you focus purely on the core rule: every row, column, and block must contain each number exactly once. The only technique needed here is scanning for the one missing number in a row, column, or block, which is the purest form of a Naked Single.
Completing a 4x4 puzzle in under 2 minutes is a great benchmark. It shows you've internalized the basic constraints and scanning pattern. Before moving on, ensure you're comfortable with the specific Sudoku 4x4 Rules as they differ slightly from the classic game.
- Don't guess. If stuck, re-scan each row, column, and block systematically.
- Use pencil marks if helpful, but try to solve some puzzles by sight alone to train your scanning speed.
Stage 2: Bridge to 6x6 Sudoku
A 6x6 Sudoku grid introduces a crucial new element: larger 2x3 or 3x2 blocks. You now use numbers 1 to 6. This stage bridges the gap between the simple 4x4 and the full 9x9 puzzle. The solving logic remains the same—find the only possible number for a cell—but with more cells to manage, you'll start using elimination more deliberately.
Here, you'll naturally begin to apply the concept of a Hidden Single. This is when a number has only one possible cell left in a row, column, or block, even if that cell has other pencil marks. Successfully solving a 6x6 puzzle in 4-6 minutes demonstrates you can handle more complex interactions. Reviewing Sudoku 6x6 Rules will clarify the block shapes for this format.
- Start by filling in the most constrained rows, columns, or blocks first.
- If progress stalls, make light pencil marks for all possible candidates in a row to spot Hidden Singles.
Stage 3: Conquer Your First 9x9 Easy Puzzles
A proper 'Easy' 9x9 Sudoku puzzle is designed to be solvable using only Naked Singles and Hidden Singles. You should not need pairs, triples, or more complex patterns. The puzzle will have many givens (typically 36+), providing a strong starting framework. Your strategy is a cycle: scan for obvious singles, which will reveal new singles, and repeat.
A good completion time for a beginner's first few 9x9 puzzles is 15-20 minutes. As you get comfortable, aim for the 10-15 minute range. If you consistently finish in this time without guessing, you have solidly mastered the beginner level. Getting stuck for longer often means you've missed a Hidden Single; our hint engine finds this is the most common hurdle for new players.
- Scan by number: Look at all instances of '1' on the grid and see where it can go in each empty row/column/block.
- Change your perspective: If stuck scanning rows, switch to scanning columns or blocks.

Should I use pencil marks for easy puzzles?
For your very first puzzles, they can be helpful. However, try to wean off them quickly to train your scanning and mental elimination skills, which are essential for progression.
I'm stuck on an 'easy' puzzle. What should I do?
You have likely missed a Hidden Single. Re-scan each row, column, and block slowly, asking 'where can this specific number go?'
What's the next step after mastering easy puzzles?
