About

Heliopoly

Features
Read full description

Heliopoly is orbital economics on the Mainline of our solar system (Helios): buy claims, burn propellant, duel rivals, and try not to go broke. Currency is Angzarr (⍼). Every buy, rent, and duel hits the Automated Interplanetary Asset Ledger. Last rocket flying wins — no timer, no “enough Angzarr.” THREE DOORS The first screen is three doors: • Arcade — the big door. One-minute play: Bot Evolution, Backup Fuel, and Hull Panel. Arcade never moves a charter you already started. • Journey — the full charter. Name a rocket, pick methane or hydrogen, and Launch against AI pilots from Mercury to the Saturn moons. • Lab — experiments. Gravity Duel practice, Deseret Letters, Urinal-rule Parking, and more. Lab unlocks after you finish one Arcade toy. Home brings you back to the doors without quitting a flight. In Journey, own systems, plant fuel depots, and stay solvent long enough for the ledger to write your name. ONLY ON THE MAINLINE • As of 2026, the only space game where a rogue Tesla can trash your fuel pods • Trade in Angzarr (⍼) — the ledger remembers every bad decision • Bring enough propellant, or become a very expensive monument • The only space game where “feral” doesn’t just apply to cats • Blank lane? Gravity Duel. Smile for the 2d6. • Last rocket flying. No timer. The cosmos does not care about your schedule. Got ideas?

HOW AN EXPEDITION FEELS • Path — One circuit: Earth → Venus → Mercury → Mars → belt → Jupiter → Saturn → home • Claims — Buy planets and moons; own a full system and rent doubles • Stations — Trade hubs that get meaner as you collect more of them • Fuel — Landing is free; leaving a gravity well costs propellant • Parking — Sit still too often and claims can go feral back to the bank • Gravity Duel — Meet another rocket on a blank lane: secret Low/High, 2d6 PLAY YOUR WAY • 2–6 pilots (you plus AI, or full self-play) • Easy through Expert AI packs • Full Helios Ops Manual in-app: rules, glossary, rival-rocket civilopedia • iPhone and iPad NO WI‑FI NEEDED Heliopoly ships the complete game in the app package.
