In Swap Sums, you will be using your thinking to apply tiles of different positive and negative values to a series of tokens with positive and negative values. Your goal is to puzzle out the order in which those tokens can be played and where they can be played to reach pure zero. The ultimate in neutrality. You'll love making your way to zero. We all have to go back to zero, we've built it up to far now. Pure zero as a goal may seem less than exciting but ultimately it is perfect grounds for a challenging and interesting game.
