- Become Blackhole follows a 5-stage growth chain: dust, asteroid, moon, planet, star, then black hole.
- Mass is the only currency: absorbing mass fills your growth bar and unlocks larger prey.
- Star map upgrades like absorption speed and gravity radius determine how fast you scale.
- The black hole is the endgame form — it can devour entire maps.
- Loop sweeping and cluster crushing are the fastest ways to grow at every stage.
The Full Growth Chain: How Big Can You Get?
In Become Blackhole, size is everything. You start as a speck of dust barely able to collect gravel, and the entire game is the journey toward becoming a map-devouring black hole. Each stage of the chain unlocks new categories of prey, and your growth speed depends on how well you match your targets to your current form.
| Stage | What You Can Devour | Growth Speed | Key Unlock |
|---|---|---|---|
| Dust | Loose dust, gravel, small debris | Slow | Passive absorption only |
| Asteroid | Small rocks, rock clusters | Moderate | Crushing ability |
| Moon | Terrain features, small structures | Fast | Wide destruction sweep |
| Planet | Hills, buildings, whole biomes | Very fast | Gravity pull on loose objects |
| Star | Planetary-scale objects | Peak | Largest targets in each zone |
| Black Hole | Everything on the map | Endgame | Devour entire maps |
Anything larger than your current form cannot be consumed. Push your mass bar by crushing clusters of smaller targets before attempting the big objects in each zone.
Mass Farming: The Engine of Growth
Mass is the resource that drives every stage transition. Efficient players keep their absorption queue full at all times — if nothing is being pulled into your gravity field, you are losing growth time.
Crush Clusters First
- Breaking a cluster spawns dozens of fragments at once
- Burst income beats isolated targets
- Best early-stage mass source
Sweep in Loops
- Circular loops passively collect drifting fragments
- No backtracking required
- Keeps momentum between zones
Save Big Targets
- High-mass objects yield more post-upgrade
- Strip dense zones late in a run
- Smooths your growth curve
The most common growth stall is chasing single large objects while ignoring fragment clouds. Fragments gathered in loops consistently out-earn solo targets per second.
Step-by-Step: Fastest Route to Maximum Size
Dust Stage: Keep Moving
Absorb scattered dust and debris fields. Avoid dense clusters you cannot consume yet, and keep moving to gather material quickly.
Asteroid Stage: Crush for Income
Break apart rock clusters and absorb the fragments. Crushing becomes your main income source from here on.
Moon Stage: Chain Destruction Routes
Smash terrain features in wide sweeping loops so destroyed objects funnel toward you. Learn map layouts to avoid backtracking.
Planet Stage: Use Gravity Pull
Drag in loose objects with your gravity pull before crushing stationary ones. Keep the absorption queue full — this is the biggest jump in growth speed.
Star Stage: Fill the Final Bar
Consume planetary-scale objects and save the highest-mass targets for last in each zone. When the bar fills, you become the black hole.
Once transformed, the black hole form can devour everything on the map — the true answer to "how big can you get" is the entire level itself.
Star Map Upgrades That Compound Your Size
Star map upgrades are permanent and carry across runs, making them the deciding factor in how quickly you reach maximum size.
| Upgrade | Tier | Why It Matters |
|---|---|---|
| Absorption Speed | S | Accelerates mass gain at every stage; best long-term investment |
| Gravity Radius | A | Larger pull radius means faster debris cleanup and less precise movement |
| Movement Speed | B | Faster zone transitions; matters less once radius is upgraded |
| Early-Stage Skins | C | Cosmetic only — you spend the least time in dust/asteroid forms |
Dump early points into absorption speed, then gravity radius. These two compound across every future run and shorten the dust-to-black-hole journey dramatically.
Growth Milestones Checklist
Road to Maximum Size:
- Reach asteroid form by crushing your first rock cluster
- Reach moon form and clear a full terrain sweep without backtracking
- Reach planet form and strip an entire biome
- Invest first star map points into absorption speed
- Transform into the black hole and devour a full map
Finish each zone next to its exit so you enter the next area at full momentum instead of crossing empty ground.
FAQ
Q: How big can you actually get in Become Blackhole?
The maximum size is the black hole form, the final stage of the growth chain. Once you fill the mass bar as a star, you transform into a black hole capable of devouring everything on the map — the entire level becomes food.
Q: What is the full growth chain from start to finish?
You evolve from dust to asteroid, then moon, then planet, then star, and finally black hole. Each stage unlocks larger categories of prey, so matching targets to your current form is the key to fast growth.
Q: What is the fastest way to gain mass at every stage?
Crush clusters instead of isolated objects — breaking a cluster spawns dozens of fragments at once for burst income. Combine this with wide looping sweeps so drifting fragments funnel into your gravity field without backtracking.
Q: Which star map upgrades help you grow bigger fastest?
Absorption speed is the single best investment because it accelerates mass gain at every stage. Gravity radius is the second priority, followed by movement speed. Skins are cosmetic and do not affect growth.
