Load 10 New Puzzles
Explore a set of ten randomly selected heptomino duplicate puzzles.
Each puzzle contains 20 heptomino pieces. Nineteen of them belong to different shape families, while one shape appears twice. Your task is to compare the pieces carefully and identify the duplicate in every puzzle.
Solve All 10 Puzzles Online
You can play through the complete puzzle pack directly on the page.
Each puzzle is interactive, so you can click or tap a piece to test your answer. If you need help, the solution can be revealed at any time.
Matching heptominoes may appear in different orientations, which can make the duplicate harder to recognize. Look closely at the outlines, corners and branches of each shape.
If you want another challenge, use Load 10 New Puzzles to generate a fresh random set from the available collection.
Print the Full Heptomino Puzzle Pack
Use Print Puzzle Set to create a printable version containing all ten puzzles in one collection.
The solutions are placed separately, so the puzzle pages can be printed, saved or shared without showing the answers too early.
This makes the set suitable for home use, classroom activities, puzzle collections, travel or quiet offline puzzle time.
Create New Random Puzzle Sets Anytime
Because the selection is random, you can generate a different group of ten puzzles whenever you like.
That makes it easy to come back for another printable puzzle pack, build a fresh collection for later, or challenge someone else with a new set of heptomino duplicate puzzles.
