Guides and FAQ
Everything you need to know about DominoLab, from basic guides to answers to the most common questions.
- Choose the tile type: dots, numbers, colours or shapes.
- Pick the set size: use the slider to set the highest value. The classic "double-six" set has 28 tiles.
- Set the tile size: we recommend 9 × 4.5 cm, which sits nicely in the hand.
- Turn on the guides: thin dashed lines help you cut accurately.
- Check the preview and click "Generate PDF".
- Print and cut out the tiles along the guides.
- Open the Picture domino page.
- Upload images: at least 3, at most 10. Seven images make a full set of 28 tiles.
- Choose a mode: "Pictures only" pairs every picture with every other, "Counting" puts a picture against a number of dots or a digit.
- Set the order: in counting mode, the order of the images decides which picture stands for which number.
- Download the PDF. Your images are processed entirely in your browser.
- 2–3 years: colours or pictures, a small set (up to 15 tiles). Recognising is enough, no counting needed.
- 3–4 years: shapes and pictures. Kids learn to name a circle, a square or a star along the way.
- 4–6 years: dots up to six and counting mode. The child links a picture to a quantity.
- 6+ years: numbers, the classic "double-six" or a bigger set up to "double-nine".
- Paper: card stock of 160–250 gsm will not bend.
- Scale: in the print dialog choose "Actual size" or 100 %, not "Fit to page".
- Cutting: a paper trimmer is quickest; with scissors, make the long straight cuts first.
- Durability: laminating gives you a set that lasts for years and can be wiped clean.
Yes. DominoLab is completely free, with no registration and no limit on how many sets you create. It is supported by ads and voluntary donations.
It depends on the highest value. The classic "double-six" set (0 to 6) has 28 tiles, "double-nine" (0 to 9) has 55. Every pair of values appears in the set exactly once.
No. Images and the PDF are processed entirely in your browser. Nothing is uploaded, and nothing is left behind once you close the page.
At least 3 and at most 10. N images produce N × (N + 1) / 2 tiles, so 5 images make 15 tiles, 7 images make 28 and 10 images make 55.
In counting mode every tile has a picture on one half and a number of dots or a digit on the other. The first picture stands for 1, the second for 2, and so on, so kids link a picture to a quantity as they play.
We recommend 9 × 4.5 cm, the 2 : 1 ratio of classic dominoes. Ten such tiles fit on an A4 page. Bigger tiles suit younger children, smaller ones make a travel set.
So the set still works when printed on a black-and-white printer, and so children with colour vision deficiency can play too. The shape always tells you unambiguously which tiles match.
Yes. On the Play online page you can play against the computer or with two players on one device, using dots, numbers or your own pictures.
Any modern browser on a computer, tablet or phone. For bigger picture sets we recommend a computer or tablet.
