Enjoy a fresh collection of ten heptomino duplicate puzzles every week.
Each challenge contains 20 heptomino pieces, with one shape appearing twice. Your task is to compare the pieces carefully and find the matching pair.
The same ten puzzles remain available throughout the entire week, giving you plenty of time to solve them online, return later, or print the full collection for offline use.
Solve This Week’s Puzzles Online
All ten weekly puzzles can be played directly in your browser.
Study the outlines and orientations of the heptominoes and click or tap the piece you believe has a duplicate somewhere else in the puzzle.
Because matching shapes can be rotated, they may look quite different at first glance. Pay attention to distinctive corners, branches and the overall structure of each piece.
If you get stuck, you can reveal the solution whenever you want to check the matching pair.
The Same Challenge for the Whole Week
The weekly selection does not change when you reload the page.
This makes it easy to stop and continue later, work through only a few puzzles at a time, or share the same set with friends, family or students.
Everyone receives the same weekly selection until the next puzzle set is generated.
