Since high school I have been bad at the board game Set.

In set there are 81 cards and each card has four attributes.

1. Number [1,2,3]
2. Shape [oval, diamond, squiggle]
3. Color [red, green, purple]
4. Shading [solid, lined, outlined]

The goal of the game is to collect bags of three cards where each attribute either has all of one type, or one of each.

In order to get better I made a simple matching game – the goal is to select the card which finishes the set for two given query cards.

It times how long it takes to make 20 matches.

You can play for yourself here.
