Black & White Heptomino Duplicate Puzzle

Can you find the duplicate heptomino without using any color clues?

This black and white puzzle contains 20 heptomino pieces. Among them, one shape appears twice. Your challenge is to study the outlines carefully and identify the matching pair.

Without colors to separate the pieces visually, the puzzle puts more emphasis on recognizing the geometry and structure of each heptomino.

Spot the Duplicate Heptomino

Look closely at the shape of every piece and compare distinctive corners, branches and outlines.

Matching heptominoes may appear in different orientations, so a rotated or reflected version can look quite different at first glance.

When you believe you have found the duplicate, click or tap the corresponding piece to check your answer.

A More Challenging Black & White Version

Removing the colors makes shape recognition even more important.

Instead of using color as an additional clue, you have to rely entirely on the structure of each heptomino. This can make even familiar shapes surprisingly difficult to recognize when they appear in another orientation.

There is no time limit, so you can examine the puzzle for as long as you need.
