About Stackmon
Stackmon blends creature collection with card‑stacking mechanics. Players explore Gaia’s seven biomes, capture over 100 Stackmon, and combine them with resource and equipment cards to trigger rarer effects.
Base building is central: construct and upgrade 25+ buildings, craft items, and automate tasks while confronting the spreading corruption known as the Soot. Rival Scout Leaders provide strategic auto‑battles that test your stacked combos and elemental affinities.
