How to Play
Each puzzle contains several different hexomino shapes, but one of them
appears twice. The matching shapes may be rotated, so they can look very
different at first glance.
Study the outlines carefully and click the shape you believe has a matching
partner somewhere else in the puzzle.
If you choose the correct hexomino, the game will reveal both matching shapes.
If you choose the wrong one, you can immediately try again.
How Many Can You Solve?
There is currently no time limit, so you can solve each puzzle at your own
pace. Try several puzzles in a row and see how quickly you begin to recognize
the different hexomino shapes.
Every puzzle has its own number, making it easy to identify a particular
challenge or compare it with someone else.
What Is a Hexomino?
A hexomino is a geometric shape made from six equal squares connected edge
to edge. There are 35 different free hexomino shapes when rotations and
reflections are considered the same shape.
A single hexomino can look surprisingly different after it has been rotated.
That makes these shapes perfect for visual recognition and duplicate-finding
puzzles.
New Puzzles Whenever You Want
The game selects puzzles from a growing collection of thousands of different
hexomino patterns. Use New Puzzle or simply refresh the page

More interactive game modes are planned, including timed challenges and other
ways to test how quickly you can find the matching shapes.
