SSxSS: Synergistic Symbiosis for Symbiote Synergy

In SSxSS, you build and manage two castles that cannot thrive alone. 

Using randomly drawn cards, create production chains and develop each castle while keeping their economies in balance. Every few turns, the castles demand specific resources from one another - forcing you to trade, adapt and maintain a healthy relationship between both sides. 

What one castle produces, the other may desperately need. 

But be careful. 

Make one castle too strong, and the other may struggle to keep up. Let either side fall behind, and the entire system can collapse. 

Your goal isn't to build the strongest castle. 

It's to build a system where both castles make each other stronger. 

Build. Trade. Adapt. 

Find the synergy. Achieve symbiosis.
