About Space Station Sim
Keep an orbiting station solvent across a grid of six Module slots. Two modules run from the start; the other four unlock as you bank enough money. Each running module slowly fills a progress bar that pays out and adds to your O2, Power, and Research counters. Spend that income on the Upgrade button (faster production) or Expand (a new module), and survive the daily upkeep bill that grows every day.

How to Play Space Station Sim
You begin with money 500 and two active modules out of six. Every production tick, each active module advances its bar; when it fills, it pays income and bumps your O2, Power, and Research counters. Tap Collect to bank the accumulated O2 + Power + Research as cash. Tap Upgrade (cost 50 times the number of upgrades bought, +20% production speed each) to produce faster, or Expand to unlock the next module for 100 times its slot number times your level. Each day a daily cost of 10 times your level plus the day number times 2 is deducted — keep money positive or it's game over.
Controls
Tap the Collect, Upgrade, and Expand buttons. Tap an active Module to nudge its progress bar. P pauses; Space starts or restarts.
Tips & Strategies
- Tap an active Module directly to push its progress bar forward by 0.2 between ticks.
- Buy a couple of Upgrades early — each one adds 20% to every module's output and compounds.
- Keep satisfaction above 60: it rises with more active modules, and you only level up every 5 days when it stays high.
Frequently Asked Questions
How do I level up?
The day counter advances every 300 ticks. Every 5th day, if your satisfaction is above 60, your level increases, which raises both income per module and the unlock cost of new ones.
How do I lose?
There are no crew or oxygen failures. The only fail state is bankruptcy: when the daily upkeep deduction pushes your money below zero, the run ends with a 'Bankrupt!' screen.
