Eat to grow
Pellets give a tiny bit of mass. Other blobs give a lot. You can eat anyone meaningfully smaller than you (~1.25× the rule of thumb). Bigger = harder to escape from, but slower to chase.
How to play Bloom
One bloom every night at 00:00 UTC. Everyone enters the same world. Last blob alive wins that night's championship. Tomorrow you do it again.
The basics
02
Don't get eaten
Bigger blobs eat you the same way you eat the small ones. When you die you can keep watching, or come back tomorrow. There's exactly one bloom per day — make it count.
03
Survive the squeeze
The red safe zone shrinks throughout the bloom. Outside it, you bleed mass per second. At the centre lurks a black hole that pulls you in if you wander too close.
Controls
Desktop
- Move mouseYour blob aims toward the cursor. Closer to the blob = slower; far away = full speed.
- SpaceSplit. Your blob halves into two; the new half launches in the cursor direction. Useful for a long-range eat or a panicked escape.
- WEject mass. Spits a small pellet of your own mass out — feed it to a teammate or use it as a thrust burst.
Mobile
- DragSame as moving the mouse — your blob heads toward your finger.
- Tap splitThe on-screen Split button (bottom-right) replaces Space.

The world
The safe zone
The big red ring. Inside is safe. Outside, your mass bleeds away every second — a few seconds is survivable, a minute outside is fatal even for a giant.
The zone shrinks faster as more players die, so the late game compresses everyone into a tiny arena where there's nowhere left to hide.
The black hole
A small dark disc at the centre of the world. It pulls everything within range — pellets, ejected mass, blobs. Touch the core and you die instantly, regardless of mass.
Big blobs use it as a kill zone: shove a smaller player past the event horizon. Small blobs use the rim as a free pellet farm. Pick your moment.
Tactics that work
- Eat pellets first. The first 60 seconds are mostly free mass. Anyone trying to fight in the opening loses momentum.
- Move toward the centre slowly. The safe zone shrinks inward — staying in the rim is fine early, but late game you're in a knife fight whether you like it or not.
- Split is a commitment. Two halves can chase faster, but each is half the mass and any predator nearby eats them for free. Use only when you're certain of the kill.
- The black hole is leverage, not loot. Don't farm it for the sake of farming — use the gravity to herd opponents toward the void.
- Final two: wait for a mistake. Symmetric stalemates last forever. Force the smaller player to risk the wall or split first.

FAQ
What time is the bloom in my timezone?
00:00 UTC is 02:00 in Brussels (CEST/summer) or 01:00 (CET/winter), 19:00 in New York (EST), 16:00 in Los Angeles (PST), 09:00 in Tokyo, 10:00 in Sydney. The countdown on the home page shows your local time until tonight's bloom.
What if I miss the start?
You can join any time during the queue (the few minutes before 00:00 UTC). Once the bloom is live you can spectate but not join until tomorrow.
Can I play with a friend?
Everyone plays in the same world. There's no team mode (yet) — but you can absolutely co-operate informally: feed each other mass, gang up on bigger blobs, share the win streak chase.
How are streaks counted?
Your daily streak goes up every consecutive day you join a bloom. Miss one day and it resets. Your top-100 streak goes up when you finish in the top 100, but only resets on a sub-100 finish — missing a day doesn't break it.
Is there a way to practice?
Not yet. We may add a sandbox mode later, but the daily ritual is the core of the game — practice means showing up tomorrow.
How do you handle cheating?
The server is fully authoritative — your client only sends inputs and the server simulates everything. Speed-hacks, mass injection and ghosting all fail at the boundary. Suspect names can be banned by handle and IP-hash. Report issues to hello@bloom.game.
