Take on a complete set of ten Hexomino Intruder Puzzles selected for the current week.
Each challenge contains thirteen polyomino pieces. Twelve of them are hexominoes made from six connected squares, while one hidden intruder is a pentomino made from only five.
Your goal is to inspect each puzzle carefully and identify the one shape that does not belong.
Solve the Same 10 Puzzles All Week
The weekly selection remains unchanged until the next week begins.
You can work through all ten puzzles in one session or solve only a few and return later to continue with the same set.
Because everyone receives the same weekly collection, you can also share the challenge with friends, family or students and compare your results.
Find the Hidden Pentomino
Look closely at the structure of each piece.
Twelve shapes contain six connected squares. The intruder contains only five, but rotations and different arrangements can make the difference surprisingly difficult to spot.
Click or tap the shape you believe is the pentomino to check your answer.
If your first choice is incorrect, simply continue searching until you find the right piece.
Print the Complete Weekly Puzzle Set
The full collection of ten puzzles can also be turned into a printable worksheet.
Keep the solution pages separate so the answers remain hidden while you work through the challenges.
The printable set is useful for home activities, classroom exercises, longer puzzle sessions, travel or anyone who prefers solving puzzles offline.
You can also save the worksheet as a PDF and keep this week’s puzzle collection for later.
A New Set Next Week
The current collection stays available throughout the week.
When the next week begins, another group of ten Hexomino Intruder Puzzles is selected automatically.
Return regularly to discover a fresh weekly challenge and see whether you can find all ten hidden pentominoes.
