Spot the Difference Maker – Create Find the Difference Puzzles

Create find-the-difference puzzles from your own photos, free in your browser.


Make your own find-the-difference puzzle

Spot-the-difference puzzles are a classic for a reason: two pictures that look identical, a handful of sneaky changes, and the satisfying hunt for each one. They work for children learning to look closely, for classrooms, for party games, and for anyone who wants a quiet five minutes of focus. Making a good one by hand, though, is fiddly work in an image editor.

This tool does the fiddly part for you. Give it a photo, choose how many differences to hide, and it produces a changed copy with small, plausible edits: a patch blended away, a recoloured region, or a copied detail moved to a new spot. Your original stays untouched, and your photo never leaves your browser.

How to make a puzzle

Choose a photo with plenty of detail: a street scene, a bookshelf, a garden, or a busy desk all work well. Plain skies and empty walls make poor puzzles, because there is nothing to change believably. Pick a difference count, three for young children, five for a family game, eight for a real challenge, and set a seed number. The same seed always makes the same puzzle, so you can regenerate a puzzle you liked or share a seed with a friend.

Press the button and the tool draws both images: the original and the puzzle copy. Download both, print them side by side or share them digitally, and let players hunt. When everyone is stuck, press show answers to circle every change on the puzzle copy.

What kinds of changes are hidden?

The tool mixes three kinds of edits. Some details are covered over with the average colour of their surroundings, like an object quietly removed. Some regions are recoloured, so a familiar object wears the wrong colour. Some details are cloned from a nearby spot, doubling something that should appear once. Mixed edits are harder to find than a single repeated trick, which keeps the puzzle fair but challenging.

Changes are placed with a minimum distance between them, so they do not cluster in one corner and leave the rest of the picture untouched. That spread matters: a good puzzle rewards scanning the whole image, not staring at one busy area.

Choosing difficulty

Difficulty is not just the count. Small changes on a busy photo are harder than big changes on a simple one. For children, use a simple photo, three differences, and larger changes by choosing a photo where the tool’s edits land on plain areas. For adults, use a detailed photo and eight differences. If a puzzle turns out too easy or too hard, change the seed and try again: a new seed shuffles every change to a new place.

Time limits add spice. Five minutes for a five-difference puzzle is a friendly family round. For classrooms, pair students up and let one partner describe a difference while the other finds it, which turns a looking game into a speaking game too.

Printing and sharing

Both images download as PNG files at the original photo’s size, so they print crisply. Print them on one page if your printer allows, or on two pages for younger players who like to point and compare. If you share digitally, send the puzzle copy first and keep the answer-circled version for the reveal.

One caution: use your own photos or images you have the right to share. A family snapshot, a photo of your own garden, or a classroom display makes a personal puzzle that no bought puzzle book can match. Try it now: pick a busy photo, hide five differences, and see how long it takes you to find them all.
