Reef Rush
Reef Rush is a collaborative and competitive strategy card game set on Christmas Island, where players take on different roles to manage the unique ecosystem.
Players work together to build a shared reef using land and ocean cards, while also competing to earn points for their own goals. You must choose between cooperation and competition, as each card you play can benefit either yourself or another player.
But there’s a catch: If the reef becomes unbalanced, everyone loses. Players must maintain a healthy reef while dealing with unpredictable events.
Reef Rush challenges players to think critically about real-world environmental management, showing how individual actions impact whole ecosystems.
Will you help the reef thrive or push it to collapse?
