A web app for practicing the card game Set. Play it at https://aarongable.github.io/webset/. Install it as a PWA for offline play.

The cards are as precise a replica of the 1998 deck (the one I grew up with) as I could get. This does sacrifice some readability of thin lines on a small phone screen, but the graphical fidelity it worth it to me.

The last card is always dealt face-down. This is a house rule based on the number theoretic properties of Set: you can always determine precisely what card it is by considering each feature one-by-one. You can enter a guess for what the last card is, or if it is part of a set you can use it directly without having to reveal it first!

Also features extensive stats to track your own biases in set-finding, and to track your improvement over time.

Simply open index.html in a browser. Pushes to main automatically deploy to GitHub Pages.

Run node --test tests/, or open tests/run.html in a browser (headless Chrome with --dump-dom works).

Debug switches:

• ?cards=15 for a short deck
• ?seed=N for a fixed shuffle
• Ctrl+Shift+E to jump to the last 12 cards of a deck without recording stats.
