Strongholds is essentially an electronic card-based military base battling game. (CBMBBG?!) The game play is simple, yet still complex enough to be interesting and fun. Your base (the one of the bottom) is pitted against the enemy across a canyon river. Your object can be one of the following: 1. Destroy your opponents base building by reducing it's health to zero. 2. Build up your base's health to 70 (default number that can be changed) in order to launch a nuke which destroys your opponent and ends the game.
