See https://tlk.github.io/spotit/cards.html for a set of 57 cards inspired by the popular Spot it! game.
Apparently, this game is built on what is called a Finite projective plane of order 7.
See https://images.math.cnrs.fr/Dobble-et-la-geometrie-finie.html (in French), or these comments on Stackoverflow:
The spotit.py script create cards from a template file with placeholders named S1, S2 .. S8.
The placeholders are replaced with emojis to make the cards colorful.
Finally, all cards are combined into a single file cards.html that can be printed out.
| Template file | Example card |
|---|---|
 |
 |
The template file is in SVG-format and can be customized using free software such as macSVG.
It is also possible to customize the emojis used to generate the cards. Be aware that emojis may not look the same on different devices and operating systems.
