The game plays in a similar fashion to Splendor (minus reserving cards & wild tokens, which will be implemented in the future.)
Click on a square token to collect it - you may collect one token of three different types per turn. If there are more than four tokens, you may collect two of the same type in a turn.
Use these tokens to pay for circular elements in the center. If you're the first to collect the necessary elements for one of the bonuses in the bottom row, you will gain those bonus points.
The first player to 15 points wins.
The three AI players aren't very good yet, this is my first real attempt to make any strategic AI, so expect improvements in the next couple days.
