Picture sudoku 6×6 — hard
How to use this worksheet
- In the left puzzle, the fifth row shows a heart, a triangle, a gap, a diamond, a square and a circle. The gap needs the star.
- The fourth row of each puzzle holds only one shape. Treat these rows as the finish line, not the starting point.
- Before drawing, lightly note in the corner of a square the two or three shapes that could still go there.
- When both puzzles are done, compare with the solution page.
What this worksheet teaches
Every row, column and 2-by-3 box must hold all six shapes once. With only 16 shapes given, many squares start with several possible shapes, so children must eliminate options step by step. Each puzzle has exactly one solution, reachable by logic alone, and tracking possibilities trains attention and working memory.
Crossing out shapes that cannot fit
For a stubborn square, list all six shapes and cross out every one that already appears in its row, its column or its box. Whatever remains is still possible. When only one shape is left, draw it. Each new shape removes options elsewhere, so one success often leads to the next.
