Merge Spaceships
Merge matching ships, deploy stronger vessels to orbit, earn automatic Credits, and recover up to 24 hours of capped offline fleet income.
Merge Spaceships gameplay
Merge Spaceships combines a merge board with an idle combat layer. Acquire low-level ships, place them in the hangar, and combine two matching levels to create a stronger vessel instead of managing a traditional upgrade list.
Hangar merging
The hangar contains a limited number of slots, so board space is part of the strategy. Matching ships can be fused upward through progressively stronger levels, and fabrication upgrades can improve the level of newly acquired ships as the economy grows.
Orbit combat and passive income
Ships moved into orbit automatically fire on passing asteroids. Stronger vessels deal more damage, and destroyed normal, gold, or boss asteroids award Credits that can be reinvested into more ships and technology.
Technology progression
Orbit Expansion opens additional deployment slots, Advanced Fabrication improves purchased ship quality, and Logistics Net increases the frequency of incoming crates. The main tradeoff is how much value to keep in the hangar for merging versus how much power to deploy for immediate income.
Offline and background fleet earnings
Supported saves can recover estimated Orbit income after at least one minute away, including when the browser keeps the tab open in the background. Recovery is capped at 24 hours and uses the deployed fleet's Orbit DPS with a 50% asteroid-availability model; it is an approximation rather than a full offscreen combat simulation.
For a more traditional incremental economy, open Galaxy Miner. For direct combat, try Star Defense.

What makes this game different?
Merge Spaceships combines a finite hangar board with automated orbit combat. The central tradeoff is whether to keep ships in the hangar for future merges or deploy them immediately so they can damage asteroids and generate Credits.
Board space turns merging into a planning problem. Two matching ships can be fused into a stronger level, but each slot used by an unmerged ship reduces the room available for future combinations. Deploying a ship frees hangar space and creates income, but that unit is no longer available for an immediate merge on the board.
Technology changes the value of both choices. Orbit Expansion creates more deployment room, Advanced Fabrication improves newly acquired ship quality, and Logistics Net affects incoming crate frequency. Because those upgrades alter the flow of ships and Credits, the best hangar strategy changes as the run develops.
Decision guide
| Situation | Practical action | Why |
|---|---|---|
| Hangar nearly full | Complete a merge or deploy a useful ship | A full board blocks flexibility and can waste incoming opportunities. |
| Orbit damage is too low | Deploy stronger merged ships | Orbit DPS drives asteroid destruction and therefore Credit generation. |
| Purchases create too many weak ships | Consider fabrication upgrades | Improving the starting level of new ships reduces the number of merge steps needed later. |
Beginner plan
- Keep enough free hangar space to combine matching levels instead of filling every slot immediately.
- Deploy ships when the Credit income from orbit is more useful than keeping those ships available for another merge.
- Upgrade fabrication when repetitive low-level merges become the main bottleneck.
- Use offline income as a convenience, not as a perfect combat simulation; it is an estimate based on the saved deployed fleet.
Limits and save behavior
Offline and background recovery is capped at 24 hours and uses an estimated Orbit-income model rather than simulating every asteroid and projectile while the page is closed. Progress is local to the current browser unless the mode provides an explicit backup feature.
