Halloween is the one season where “a bit messy” counts as a design goal. So here is a small feature with a lot of seasonal mileage in it: the Puzzle Creator on Oh, my Dots! can cut any picture you give it into pumpkin-shaped pieces.
Not a picture of pumpkins cut into squares: actual pumpkins, stem and all, tiling across your photo. Upload a class photo, a drawing your kid made, last year’s costume, a spooky stock image, and it comes back as a puzzle made of little jack-o’-lantern silhouettes. It’s free, it works without an account, and you can play it on screen or print it out.
There are two pumpkin shapes in the list, and the difference between them matters more than it first looks. One of them is built to be cut out with scissors, and it’s genuinely much less work.
First, a quick refresher: what’s a swap puzzle?
A swap puzzle scrambles a picture into tiles and asks you to put it back by swapping pieces around, rather than by fitting unique jigsaw shapes together. Every piece is the same shape, which is exactly why the shape is free to be something fun, like a pumpkin.
If you’ve never made one, the full guide to swap puzzles walks through the basics. This article is about the Halloween shapes specifically.
The two pumpkin shapes
Open the Puzzle Creator’s shape dropdown and, alongside the usual Rectangle, Triangle, Hexagon and Heart, you’ll now find:
- Pumpkin
- Pumpkin 2 (best for printing)
Both make a real, playable puzzle. Both can be printed. The labels are a recommendation, not a restriction. You are not locked out of playing “Pumpkin 2” on screen, and you can absolutely print a puzzle made with “Pumpkin”.
What actually changes is how the pumpkins tile together, and that’s what makes one of them a much friendlier thing to hand a seven-year-old with a pair of safety scissors.
Pumpkin is the classic one: a round, plump jack-o’-lantern with a little stem on top, sitting in staggered rows that barely overlap. Every piece reads as its own distinct pumpkin, which is exactly what you want when you’re sliding them around on a screen.
Pumpkin 2 is a much tighter tessellation. Its pumpkins have a rounded top and a tapered base, and each row nests halfway into the row above, so the pieces lock together like fish scales or roof tiles. The part that matters: each pumpkin shares its outline with its neighbours instead of carrying one of its own.
Why “Pumpkin 2” is so much easier to cut out
This is the part worth knowing about, because it’s invisible until you’re standing at the printer.
When you print a puzzle made with the regular Pumpkin shape, every single piece gets its own complete dashed outline. Forty pieces means forty separate pumpkins to trace around with the scissors, and because each neighbour carries its own line too, you end up with pairs of nearly-parallel lines running between the pieces, plus a fiddly little notch to negotiate at every stem.
Pumpkin 2 only draws an outline for every other row. The rows in between don’t need one: they’re already bounded by the lines around them. What lands on the paper is a lattice of long, continuous wavy bands rather than a page full of closed loops, so you cut along one flowing line and separate an entire row of pumpkins in a single sweep.
That works out at roughly a third fewer lines on the page, and, more to the point, they’re smooth curves you can follow in one go instead of several dozen individual outlines to trace. If you’re printing thirty copies for a classroom, that difference is most of an afternoon.
So the rule of thumb is simple:
- Making it to play on screen? Either shape works. Pumpkin gives you rounder, more obviously pumpkin-shaped pieces.
- Making it to print and cut out? Pumpkin 2 (best for printing). It’s labelled that way for a reason.
How to make one, step by step
1. Open the Puzzle Creator
Head to the Puzzle Creator. No account, no sign-up, nothing to install.
2. Pick your picture
Click to choose an image, or just drag one straight into the page from your desktop. Anything works: a photo, a drawing, a downloaded illustration.
3. Crop it
The Crop the image step lets you trim to the part you actually want. Worth spending ten seconds here: a tight crop on a clear subject makes a far better puzzle than a wide shot with your subject small in the middle.
4. Choose your pumpkin
In the shape dropdown, pick Pumpkin or Pumpkin 2 (best for printing). The preview redraws immediately, so you can flip between them and see exactly how each one tiles across your picture before you commit.
5. Set the number of pieces
Drag the slider to choose how many pieces you want, anywhere from 4 up to 100. The exact values you can pick depend on the shape of your image, since the pumpkins have to tile evenly across it, so the slider offers the counts that actually work rather than every number in the range.
A rough guide:
- 9 to 16 pieces: preschool and early primary
- 20 to 35 pieces: comfortable for most kids
- 40+ pieces: genuinely challenging, especially with pumpkins
Bear in mind that pumpkin pieces are harder than rectangles at the same count. The outline gives you fewer straight-edge clues to work from, so pick a slightly lower number than you normally would.
6. Preview, then play or print
The Preview the game step shows you the finished puzzle. From there you can play it straight away in the browser, or go to Print Preview and send it to paper.
Choosing a picture that works
Pumpkin pieces are more forgiving of bold pictures and much less forgiving of busy ones.
- High contrast wins. Strong colour blocks give players something to navigate by.
- Clear subject, simple background. A face, a costume, a carved pumpkin, a single strong shape.
- Avoid large flat areas. A big patch of identical black sky is nearly impossible to place, because the pieces are interchangeable in every way that matters.
- Watch the busy ones. A detailed autumn-leaves photo at 60 pumpkin pieces is a genuinely hard puzzle. That might be exactly what you want; just go in knowing.
Printing a set for a classroom
If you’re printing for a group, add a header before you print: Oh, my Dots! can put Name:, Date: and Class: fields at the top of the sheet, which saves you writing thirty names by hand. There’s a full walkthrough of the custom print headers if you haven’t used them.
A few things that help in practice:
- Print on the heaviest paper your printer will take. Card stock makes pieces that survive more than one lesson.
- Cut one copy yourself first as a test. You’ll immediately see whether your piece count is right for the group.
- Print the original picture too, uncut, as a reference sheet, especially for younger children.
- Use Pumpkin 2 (best for printing). Thirty copies is a lot of scissors work, and taking a third off that is not a small thing.
What else is out there for Halloween
Once you’ve made your own, the Halloween Special page has a whole collection of ready-made Halloween games: connect-the-dots, picture mazes, swap puzzles, a word search and a crossword, all free to play and print. Our Halloween round-up goes through what’s on it.
One honest note: the ready-made Halloween swap puzzles on that page use the standard rectangle, triangle and hexagon pieces. Pumpkin-shaped pieces are something you make yourself in the Puzzle Creator, and that’s the only place they live right now. Which, given it takes about two minutes and any picture you like, is not much of a catch.
Happy haunting. 🎃
