Shapes sudoku

Shape sudoku swaps the numbers for shapes, a circle, a square, a triangle and a star, so a child too young to read digits can solve it by matching pictures. The grid is a gentle 4x4, each shape appearing once per row, column and box. Every puzzle has exactly one solution and prints with its answer, so you can check it together.

Grid size

9×9 is standard. 4×4 and 6×6 are kids sudoku, easier and quicker to solve.

Symbols

Shapes instead of numbers, for young children who can't read digits yet.

Difficulty

Higher grades need harder solving techniques, not just fewer given numbers.

Layout

Symmetric gives the classic newspaper look.

Two pages: the puzzle and its solution. Every board has exactly one solution, generated by the same engine as our KDP studio.

How to solve a sudoku

Every grid has exactly one answer, and you reach it by logic alone. A well-made sudoku never needs a guess.

The method

1Look for the only number that fits. Scan each row, column and box for a square where every other number already appears somewhere it can see. The one number left is the answer for that square.
2Pencil in the candidates. In a square with a few numbers still open, note them small in the corner. As you fill its neighbours, cross the used numbers off until one remains.
3Work one box at a time. A number appears once in every box. If two of a box rows or columns are already blocked for a number, the third holds it.
4Check as you go. No number repeats in any row, column or box. If one does, a recent mark was wrong, so rub it out and try the next deduction.

The one rule: Fill the grid so every row, every column and every box holds 1 to 9, each exactly once.
What the answer page shows: Every solved grid is printed at the back, so you can check a single square or the whole puzzle.
How the grades differ: Easy puzzles solve on single numbers alone. Harder grades ask for candidate marks and longer chains of reasoning, never a guess.
Good for: Beginners learning the moves, and regulars who want a graded run from gentle to brutal.
