Platon³
SteamPlaton³ is a strategic deckbuilding game where every decision matters. Build a deck of unique cubes, create powerful synergies, and push your score higher than ever.

Each color embodies its own philosophy and shapes how your cubes behave. With unique upgrades, explore a wide variety of combinations and adapt your strategy every run. Building your deck is only the beginning—place your cubes carefully on the grid and unlock their full potential.

With each new round, unleash the Platonic solids. These mysterious entities grant new cards and upgrades, gradually transforming your deck. But be warned: the deeper you go, the higher the score requirements become. Will you be able to craft the ultimate deck?

Review your deck at any time to plan ahead and optimize your synergies. Every placement, every combination can make the difference.

No two runs are the same. Discover new interactions, explore the endless possibilities of mathematics, and let the Platonic solids guide you.
Push your limits, refine your strategy… and try again to beat your highest score.
Will you dare to master the laws of geometry and reach perfection?
