A browser-based single-player implementation of the card game SET. It is snappy and efficient so you can get your optimal time.

The goal is to find sets among the cards on the board. A set is three cards where, for each of the four attributes (number, shape, fill, colour), the values across the three cards are either all the same or all different.

Click three cards to select them. If they form a valid set, they're removed and replaced from the deck. If not, you get a brief "Not a set!" flash and can try again.

The game ends when there are no sets among the remaining cards (deck + board combined).

• Light/dark theme toggle
• Different UI speeds for casual play and speedrunning
• Hints for when you are stuck or a cheater
• Auto-reshuffle when no sets exist on the board
• Top 5 leaderboard saved locally
• Works well on mobile browsers
• The cards orient vertically in portrait mode, and horizontally in landscape mode
• Can be installed as a Progressive Web App
