67 Steal a Brainrot GameBack to the main gameMerge Galaxy is a free browser game where you aim, shoot, and stack planets inside a gravity well until they combine into something much bigger. No download needed, and it runs on phones and tablets as well as desktop, so you can play at school or work whenever you have a few minutes. The core idea is simple: keep merging smaller planets into larger ones without letting the pile overflow. It sounds easy. It is not.
What is Merge Galaxy?
Merge Galaxy is a casual arcade game that mixes the logic of a merge puzzle with the physics of a gravity simulation. You have a circular orbit zone and a queue of planets waiting to be launched. Fire a planet in, and it will drift until it touches another planet of the same size. When two matching planets collide they merge into a single larger one. Keep chaining merges up through the size ladder until the two biggest objects in the game smash together and vanish, clearing space and earning a big points bonus. If the stack grows too tall and planets spill out of orbit, the game ends. The rating is 4.5 out of 5 from over 400 players, which reflects how well the one-more-go tension holds up.
How to aim and launch planets
Controls are the same on desktop and mobile. Grab the planet at the bottom of the screen and drag it like a slingshot. A dotted path shows exactly where the planet will land before you let go, so there is no guessing.
| Action | Desktop | Mobile |
|---|---|---|
| Grab planet | Click and hold | Tap and hold |
| Aim | Drag mouse left or right | Drag finger left or right |
| Launch | Release mouse button | Lift finger |
| Preview trajectory | Visible while dragging | Visible while dragging |
Scoring and the planet size ladder
Every merge earns points, and bigger merges earn more. The planets scale from a small rocky body all the way up to a radiant sun at the top of the chain. Getting to the sun requires repeated high-level merges, so each run is a long sequence of decisions about where to place each incoming planet.
| Planet tier | How you get it | Points value |
|---|---|---|
| Tiny rock | Starting piece from queue | Base |
| Small planet | Merge 2 tiny rocks | Low |
| Medium planet | Merge 2 small planets | Medium |
| Large planet | Merge 2 medium planets | High |
| Gas giant | Merge 2 large planets | Very high |
| Sun | Merge 2 gas giants | Maximum (pair disappears) |
Tips for keeping the orbit clear
- Check the queue before you shoot. Knowing the next planet lets you place the current one in a spot where a follow-up merge is ready.
- Aim for the sides when the centre is crowded. Planets near the edge are easier to reach with future shots.
- Avoid stacking the same size in a column. If two planets of the same size end up far apart, connecting them becomes harder as the pile grows.
- Prioritise merges at the top of the stack. Clearing height buys time more reliably than clearing width.
- Do not rush. The game has no time limit per shot, so take a moment to trace the path guide before releasing.
Is Merge Galaxy free and can I play unblocked?
Yes, Merge Galaxy is free with no login or download required. It runs entirely in the browser, so it works on any device with an internet connection. Because it is a browser game rather than an app install, it is accessible in most school and work networks where game sites are not specifically blocked. Progress and high scores are tracked locally in the session, so beating your record is a personal challenge each time you play.
