Build a tree with the cards. Starting with the purple circle with the dot in it, the start symbol, you can grow your tree by placing cards under it, that match in symbols. The lower card should always have the same symbol on top as the upper card has on the bottom. This behaves like a Type 2 grammar, with the Square, Cross, And Full Circle being terminals, and the other symbols Non Terminals. So you build your own small world, by growing your tree.

The goal so far is, to get the most points, by adding cards with high points to your tree. But this can be balanced much better and also automatic checking if cards are compatible would be great with more time :)
