- Become Blackhole how to absorb planets: unlock planet targets by growing through the full evolution chain.
- Mass is everything: crushing clustered objects beats chasing isolated targets every time.
- Gravity pull first: drag loose debris toward you before smashing stationary terrain.
- Absorption Speed is the best early star map upgrade — it compounds across every run.
- Reach planet size: only planet-stage bodies can devour whole landscapes and buildings.
How Planet Absorption Works in Become Blackhole
In Become Blackhole, you start as a speck of dust and climb a cosmic food chain: dust, asteroid, moon, planet, star, and finally black hole. Absorbing planets is the mid-game milestone that unlocks the fastest mass gains in a run — but planets only become edible once your own mass reaches planet stage. Until then, larger bodies are simply immune to your gravity.
The core mechanic is a gravity field with an absorption radius. Objects caught inside your pull spiral toward your event horizon and convert into mass. Bigger objects yield more mass but require a bigger form to consume.
| Growth Stage | What You Can Absorb | Key Unlock |
|---|---|---|
| Dust | Loose dust, gravel, debris fields | Passive collection only |
| Asteroid | Small rocks, crushed fragments | Active crushing unlocked |
| Moon | Terrain features, small structures | Sweep-based destruction |
| Planet | Hills, buildings, whole biomes | Gravity drag on loose objects |
| Star | Planetary-scale objects | High-mass target consumption |
| Black Hole | Everything on the map | Endgame devouring |
Mass thresholds gate everything. If a planet won't break, you are not too weak in upgrades — you are simply still in the wrong form. Farm smaller clusters until you evolve.
Step-by-Step: From Dust to Planet-Eater
Planet absorption is not a late-run trick — it is the reward for an efficient early and mid game. Follow this route to hit planet size as fast as possible.
Hoover the Debris Fields
As dust, keep moving through scattered material in wide arcs. Anything larger than you cannot be consumed, so avoid dense clusters and gather loose dust and gravel continuously.
Crush Clusters as an Asteroid
Once you become an asteroid, break rock clusters first. Cluster crushing spawns dozens of fragments at once — a mass burst isolated rocks cannot match.
Sweep Terrain as a Moon
As a moon, smash terrain features in wide looping routes so destroyed objects funnel into your gravity field. Learn map layouts to chain destruction without backtracking.
Devour Landscapes as a Planet
At planet size, hills, buildings, and biomes become food. Use gravity pull to drag loose objects in before crushing stationary ones, and keep your absorption queue full at all times.
Bank Points into the Star Map
Spend run points on Absorption Speed and Gravity Radius so the next dust-to-planet climb is dramatically shorter.
Players often save dense high-mass zones for early in a run. Reverse it — leave the heaviest clusters for after your gravity radius and intake upgrades, when you can strip them in seconds.
Best Upgrade Priorities for Faster Planet Absorption
The star map is where runs compound. Points earned during each run buy permanent upgrades, and the right order can cut your dust-to-black-hole time significantly.
| Upgrade | Tier | Why It Matters |
|---|---|---|
| Absorption Speed | ★★★★★ | Accelerates mass gain at every stage; best long-term investment |
| Gravity Radius | ★★★★☆ | Larger pull radius = less precise movement, faster debris cleanup |
| Movement Speed | ★★★☆☆ | Helps zone transitions, matters less once radius is upgraded |
| Form Skins | ★★☆☆☆ | Purely cosmetic, no growth benefit |
Loop Routes
- Move in circular loops, not lines
- Fragments drift into your field as you circle
- No backtracking required
Cluster First
- Grouped objects over isolated ones
- Cluster breaks = mass bursts
- Sweep fragments immediately after
Chain Exits
- Finish each zone next to its exit
- Enter new areas at full momentum
- Never cross empty ground
Your absorption rate only pays off when mass is in the pipeline. If nothing is being pulled in, you are losing time — always park yourself at the edge of the next destructible group.
What You Can Devour at Each Scale
Each stage of the growth chain unlocks a new tier of prey. Planets and their landscapes sit at the middle of the chain and feed directly into the star stage.
| Target Type | Available From | Mass Yield | Difficulty |
|---|---|---|---|
| Dust and gravel | Dust stage | Low | Trivial |
| Rock clusters | Asteroid | Medium | Easy |
| Terrain and structures | Moon | Medium-High | Moderate |
| Hills, buildings, biomes | Planet | High | Moderate |
| Planetary-scale objects | Star | Very High | Challenging |
| Entire maps | Black Hole | Maximum | Endgame |
Save the highest-mass targets for last in each zone. This keeps your growth curve smooth and means you enter the star stage with the densest material already banked.
Planet-Absorption Run Checklist
Use this checklist to audit your runs and make sure every planet-stage sweep is maximized.
Every Run Should Hit These:
- Crush at least one full rock cluster before leaving asteroid stage
- Complete moon-stage sweeps without backtracking
- Enter planet stage with dense zones still unharvested
- Keep absorption queue full at every moment of planet stage
- Bank all run points into Absorption Speed and Gravity Radius
FAQ
Q: How do I absorb planets in Become Blackhole?
You can only devour hills, buildings, and whole biomes once your own body reaches planet stage in the growth chain. Farm rock clusters and terrain as an asteroid and moon until your mass bar pushes you into planet form, then use gravity pull to drag loose objects in before crushing stationary ones.
Q: Why can't I crush a planet even with upgrades?
Mass thresholds are tied to your evolution stage, not your upgrade level. If a large body will not break, you are still in the wrong form. Return to smaller clusters, grow your mass, and evolve first.
Q: Which star map upgrades speed up planet absorption the most?
Absorption Speed is the single best investment because it accelerates mass gain at every stage. Gravity Radius is a close second, since a larger pull field cleans debris fields faster and requires less precise movement.
Q: Is it better to crush clusters or single big objects?
Clusters, almost always. Breaking a grouped set of objects spawns dozens of fragments at once for a burst of mass, while isolated targets give far less per second. Save single high-mass objects for after your gravity radius and intake are upgraded.
