Explore astrobiology in our solar system! Based on the original food web building game, ECOLOGIES, this game speculates about what kind of life may have existed, or might someday exist, in our own solar system. Using real science, and in collaboration with a NASA JPL educator, we imagine what life might need to survive on 7 unique celestial bodies.

Designed by a biology teacher, the game includes 78 unique organism and "life requirement" cards, 7 celestial bodies, and beautiful scientific art. (108 cards total)

The goal is to build healthy food webs on different celestial bodies. If you create a healthy ecology you are rewarded with the perks and powers of that celestial body. Each organism card lists what it eats and what it's eaten by. Cards are arranged with producers on the bottom, predators on top. This deck also includes new "life requirement cards" that need to be in place before you can add a producer. There is a trade mechanic where players trade with others based on what their individual needs are. It is a race to get 12 victory points, and different organisms give different points. There are terrestrial and cosmic factor cards that can affect opponents, and different strategies such as focusing on one celestial body, going for perks and bonuses, or disrupting other ecologies.

Gameplay Overview
Ecologies: Solar System is a standalone sci-fi take on the biology classroom favorite Ecologies, developed by a biology teacher in collaboration with a NASA JPL educator and grounded in real astrobiology science. Rather than building food webs in Earth ecosystems, players speculate about what life might look like on seven distinct celestial bodies across our solar system — from icy moons to rocky planets — constructing organism chains from producers at the base up through apex predators at the top, all based on actual ecological trophic level science. New "life requirement" cards must be played before producers can be placed, adding an extra layer of planning and interdependence. A Catan-style trading mechanic keeps players interacting and negotiating as they compete to reach 12 victory points first, with cosmic factor cards adding disruption and surprise along the way. With a standard mode, simplified rules for younger players, and a full solo mode, it's a rare game that genuinely works as both a classroom teaching tool and a satisfying strategy game night.
