Orbitfall

Pull back, let go, and bend your probe around a gravity well into the wormhole. The fewer flicks it takes, the better your score. Orbitfall is space golf with real gravity. The aim line only shows the start of your curve — never where you land — so every shot is a read, not a trace. Miss and you can recall the probe instantly and try the line again. FIVE REGIONS, FIVE NEW RULES • First Light — clean launches and steady gravity • Ember Reach — dense fields with several wells pulling at once • Reverse Field — repulsors that shove the probe away • The Drift — wells that orbit, so timing matters • Eventide — boost gates and everything combined Every sector is checked for at least two clean solutions before you ever fly it, so there is always a line to find. DAILY ORBIT — FREE, EVERY DAY Five sectors, the same five for every player worldwide. Your total flicks is your score, fewest wins, and the day's board is there without an account. KEEP A FLIGHT RECORD Lifetime flicks, per-sector bests, stars, medals, and unlockable probe trails. Share a card of your exact shot so a friend can watch the line you flew. WHAT'S FREE The first 12 campaign sectors, the full Daily Orbit and its leaderboard, medals and trails. No ads. Plays offline. GO PRO A one-time unlock or the StackForge Play Pass adds: • The rest of the campaign — every sector past 12 • Hardcore — fly the campaign with no aim preview at all • Weekly Gauntlet — a ranked seven-sector run with its own board • Flight Log — replay your best launch for each cleared sector, plus your career totals The Play Pass unlocks Pro in every StackForge game, plus One Good Thing.
