Read the full game description
Entropy is a strategy game about scientists constructing entire solar systems. On a turn, a player moves their Scientist one to three spaces around a shared rondel and resolves the chosen action, gaining resources, manipulating celestial bodies, and advancing the conditions needed for major objectives. Multi-use cards and a tightly linked economy force players to choose between immediate efficiency and long-term structure, while set collection and end-game bonuses reward coherent systems. Every player pursues the same six objectives, but the game ends as soon as one scientist completes two of them, keeping the race visible and interactive. A dedicated solo mode preserves the system-building puzzle for one player.
