CRx is an addictive strategy game designed for iPhone users, offering gameplay for 2 to 8 players. The main goal of CRx is to dominate the board by eliminating your opponents' orbs strategically. Players strategically place their orbs in cells, and when a cell reaches critical mass, it explodes into surrounding cells, adding an extra orb and claiming the cell for the player. If a player loses all their orbs, they are eliminated from the game.

CRx includes features like CPU mode for single-player games against the computer, multiplayer mode for more engaging gameplay with friends, elegant gameplay mechanics, and theme variations in Black and White. With its engaging gameplay and strategic depth, CRx promises an enjoyable gaming experience for players of all skill levels.
