Puzzle Game Logic

Given how heavily based on physics this game is -- shapes don't necessarily fit together, things blowup and the shapes go flying everywhere -- I don't think that there is a direct way to generate valid 3-connect situations at all times.

Playing a little bit right now I ended up in a situation without 3-connect shapes available and I had for more shapes to drop.
What you have to do is to use probability and determine for each shape a minimum ammount that should be available on the scene so that they will probably end up together.

This is a pretty interesting game. Good luck with your puzzle
