My first challenge was to develop a game system that resulted in interconnected and interdependent pieces.

Each aspect of the game would need to be built upon the previous so that choices made by the players would affect the overall stability of the board.
I came up with a tiled based system centered around a hexagon. Each shape can only be placed if it is touching certain other pieces. If one piece is destabilized or removed it results in a cascade of destabilization

The complexity offered by this system is two-fold.

1. The tiles relationship to other tiles

2. The tiles specific geometry.
