Arena
Moves: split, shoot mass, boost, binoculars
Updated 2026-10-28
In a match your bubble has four moves: splitting (SPLIT), shooting mass, boost and binoculars, plus 15 emotions. On a phone the moves are on the control pad buttons; on a computer, on the keys and the mouse.
| move | phone | computer | what it does |
|---|---|---|---|
| Split | the SPLIT button | Space | splits your bubble in two, and one half dashes forward. Up to 8 parts |
| Shoot mass | the shoot button | W or the left mouse button | a chunk of mass flies out, and your bubble gets smaller |
| Boost | the boost button | E or the right mouse button | fires the projectile you picked up: a bomb or a freeze |
| Binoculars | the binoculars button | none | zooms the camera out for 7 seconds, then recharges for 20 seconds |
| Emotions | the emotions panel | number keys 1–9 and 0, plus five more on Shift + 1…5 | 15 emojis, about 2.5 seconds between two |
In a raid on a computer, Q is the bomb and E is the freeze. All keys and settings are on the “Controls” page.
Splitting
The SPLIT button splits your bubble in two, and one half dashes forward. That is how you catch a bubble smaller than you. You can have up to 8 parts.
The parts merge on their own. The time depends on the bubble’s total mass:
| total mass | time until the parts merge |
|---|---|
| up to 2600 | 10 seconds |
| 5000 | about 13 seconds |
| 10,000 and up | 18 seconds |
Each new split starts the countdown over. Being torn apart by a bomb or a gem starts the same countdown. While you are frozen the countdown is paused. The “Merge in: N” timer shows the time left.
Money is split along with the mass: split in two, and each half holds half the amount. If one part is eaten, that part’s money drops onto the map as a chest and the rest is safe.
When to split and when not to
- Parts are compared with a rival one by one. To eat, a part itself must be at least 10% heavier than the rival and cover more than half of it. So splitting in two to hunt makes sense when you are at least 2.2 times heavier than the rival.
- Do not split next to a big rival: a bubble that is bigger than each of your parts eats them one at a time, even if together they are heavier than it.
- Bubbles show no mass number, so sizes are compared by eye. The expanded leaderboard shows the mass of the four heaviest bubbles.
- A gem tears apart a part heavier than 500, and a hamster tears apart a bubble bigger than itself. Small parts are safe: a gem doubles a part lighter than 500, and a part smaller than a hamster passes through it.
Shooting mass
A chunk of mass flies out of your bubble. Use it to push items and to feed a teammate. Every shot makes your bubble smaller.
- You can push a hamster toward a rival by shooting mass at it: the hamster tears apart a bubble bigger than itself.
- Mass you shoot out is seen and eaten only by your own group: free players’ mass by free players, paid players’ mass by paid players. You can feed a friend only if you both joined with the same kind of entry.
- Mass does not turn into CBW: what you leave the map with is the CBW in your bubble, XP and SCORE.
Boost: bomb and freeze
In the arena, a boost is a projectile you picked up: a bomb or a freeze. The boost button fires it. In the shooting range, the word “boost” means a bet multiplier.
- You have one projectile slot: until you fire the one you picked up, you cannot take another.
- A projectile flies in the direction you are steering.
- A bomb sticks to the bubble it hits and explodes 4 seconds later. The part bursts into pieces and mass flies out of it. The money stays in the parts.
- A freeze stops the whole bubble for 4 seconds. A frozen bubble cannot move or split, but it can shoot.
- A player holds one effect at a time: a frozen player cannot be blown up right away.
- A projectile that misses keeps flying. For the first second it is harmless to you; after that it can hit you too.
- If you eat a bubble with a bomb stuck to it, the bomb blows you up.
- Free and paid players do not hit each other with projectiles.
What the projectiles look like on the map: “Items on the map”. In the fight with Blub, only bombs take his lives: “Blub, the boss on the shared map”.
Binoculars
The binoculars zoom the camera out for 7 seconds, then recharge for 20 seconds. They work only on a phone.
Emotions
15 emojis. The pause between two emotions is about 2.5 seconds. An emotion shows as a circle on your bubble, and players nearby see it. On a computer the emotions are on the number keys 1–9 and 0, plus five more on Shift + 1…5.
In the arena, the button next to the emotions asks Blub the helper: one tap, 10 seconds for your question, and Blub answers by voice. On a computer, press V (see “Your first 10 minutes”).
Questions and answers
Why don’t my parts merge? Every new split, and every tear from a bomb or a gem, starts the countdown over, and while you are frozen it is paused. The “Merge in: N” timer shows the time left.
Why was I eaten part by part when together I was bigger? Parts are compared with a rival one by one: the rival was bigger than each of them (see “How the game works”).
