How to Play
Galcon: Space War Game Online is a real-time galaxy conquest strategy game. Every planet shows its garrison as a number and keeps producing ships until its magazine is full. Wear down neutral and enemy garrisons, hold what you take, and eliminate every rival fleet to win the war.
- The number in the middle of a planet is its garrison. Owned planets keep producing ships and refill in about 7 seconds; bigger planets hold more ships and produce them faster.
- Neutral planets have their own garrison: send more ships than the number shown and the planet becomes yours, with the surplus staying as your new garrison.
- Enemy planets work the same way - knock the garrison down to zero and the planet flips to you. Sending ships to an already full planet is never wasted: they are banked into a permanent upgrade.
- Eliminate every rival planet and fleet - the last faction standing conquers the galaxy!
Pro Tips
- Start by swallowing small neutral planets near you - each captured world produces more ships.
- Select several planets and launch one massive volley to crack a heavily defended enemy world.
- Reinforcing a full planet is never wasted - the extra ships accumulate into a permanent upgrade that raises its size, capacity and output.
- Keep an eye on rival fleets already in flight - a faction without planets can still strike back and win.

What is Galcon: Space War Game Online?
It is a free real-time planet conquest strategy game you can play instantly in the browser. You own planets, send fleets across space and conquer neutral and enemy worlds until every rival is eliminated.
How do I send ships in this space war game?
Press and drag across your blue planets to select them (several at once), keep holding, move to the target planet - neutral, enemy or friendly - and release. Your selected planets launch their full fleet toward it.
How do planets and fleets work?
The number on each planet is its garrison. Owned planets keep producing ships up to their capacity; launching a fleet spends that garrison, so attack with enough ships and keep some home. Neutral planets must be worn down to zero first, and any surplus ships you sent stay as your new garrison.
Which game modes are available?
Campaign mode is a 20-battle galaxy conquest ladder against up to four AI factions. Quick Battle is fully customizable: 1-4 AI rivals, four AI levels (including Expert), compact / standard / wide galaxies, and three rule modes - Free-for-all, Blitz (faster production) and Empire (no neutral planets).

Yes. Galcon: Space War Game Online is completely free with no downloads or sign-up. It runs in any modern browser on desktop, tablet and mobile.

About Galcon Space War Game
Galcon: Space War Game Online is a fast real-time planet war game. Every planet you own keeps producing ships until it is full; drag over your blue planets to select several at once, then release over any planet to send the fleet. Capture neutral worlds to expand, break through enemy defenses and be the last power standing in the galaxy.
Built on the classic Galcon real-time formula: a 20-level campaign that ramps from two factions to five-way brawls, customizable quick battles (1-4 AI rivals, four AI levels, three map sizes, three rule modes), seeded random galaxies, and an overfill-development system that turns surplus ships into permanent planet upgrades.
Galcon is a planning game disguised as a space brawl: every expansion is a bet on where your borders can hold. It trains strategic planning, attention switching, anticipation and resource trade-offs: decide when to empty a garrison to attack, when to reinforce your worlds, and how to out-pace several opponents at once.
