About this game
Stackmon is a creature-collecting adventure with a unique card-stacking twist. Discover and capture new creatures and stack them with resource and equipment cards to unlock even rarer items and effects. Build up your camp, explore a vibrant world, and take on rival Scout Leaders, as you uncover the dark mystery behind the Soot – a strange corruption spreading across the land.

- 25+ different Buildings to construct and upgrade your home base
- 20+ Equipment and Item cards to buff your Stackmon and Scouts
- 7 unique biomes to explore, each with their own game altering mechanics
Drag and drop Stackmon, resources and items onto each other to form powerful combinations! Use your Stackmon to gather materials, craft items, automate tasks and battle other Stackmon. Grow and customize your Harmony base to unlock new recipes, upgrades, and abilities for your Stackmon.
Discover and collect over 100 rare and powerful Stackmon and train and evolve them into their more powerful forms. Search for wild Stackmon across the world of Gaia, open booster packs to expand your collection, and help Professor Pine in his dream of completing the Stackpedia!
Venture beyond your base and challenge other Scouts scattered across the world to prove your strength and rise your way through the ranks. Take on rival Scouts in strategic auto-battles, using equipment, abilities and elemental affinities to your advantage. Face off against powerful Scout Leaders and show the strength of Harmony!
A mysterious and dangerous force is spreading throughout Gaia, corrupting any Stackmon and Scout Leaders in its path... It's up to you and your Stackmon to find the source of the corruption, face the Soot and change the fate that approaches.

Golden Stackmon are here!
Hey Harmony Scouts! We've got an exciting update for you today, just in time to celebrate Steam's Autumn Sale and China's Golden Week... We've added a brand-new rarity type to Stackmon, Golden! ✨ Golden Stackmon can appear anywhere Stackmon normally spawn, including in the wild and in card packs, but are much rarer than other Stackmon types. Maybe the Foil Maker can help you out too... 👀 Not only that, but we have also added 2 new rival scouts that can be found after beating the game (and they love golden Stackmons as much as we do!) Alongside this, we've also made some UI adjustments to improve readability on Steam Deck, and added Steam Badges, Emoticons and Trading Cards! To celebrate Golden Week and the new Golden Stackmon update, we've also got a 20% discount live right now until October 15th. We hope you have a great time filling your Stackpedia with Golden Stackmon, and if you're enjoying the game we'd really appreciate if you could leave us a review. We're always reading through your bug reports, feedback and suggestions and if you encounter any issues, please reach out to us on our Discord server. Thank you all for supporting us and giving us the opportunity to keep working on new content! ~ Joarez & everyone at Riftpoint EntertainmentRead full article on Community Announcements (anna)Patch NotesOfficial
