How the game works
Updated 2026-10-07
A match is one run on the map: from the PLAY button until you leave through the house or die. A match has no timer.
Who you can eat
You eat another bubble on two conditions: you are at least 10% heavier than it, and you cover more than half of it (55%).
Bubbles show no mass number, so sizes are compared by eye. If you are clearly bigger than a rival, you can eat them. Bubbles of almost the same size do not eat each other.
The parts of a split bubble are compared one by one. A bubble that is bigger than each of your parts will eat them one at a time, even if together they are heavier than it.
What you see on screen in a match
| where | what it shows |
|---|---|
| Under a bubble’s name | how much CBW is in the bubble — yours and other players’. Bots and free players have no label |
| The “Profit” line | the CBW in your bubble, entry included. A free match does not have this line |
| The “Score” line | your points for the match |
| The “On Map” line | how much CBW is on the map right now |
| The XP icon | experience earned in the match |
| Leaderboard | your place and the number of players. The expanded list shows the four heaviest bubbles on the map and you; the number on the right is the bubble’s total mass (5.4k means 5400) |
| House | while the exit is closed, the seconds until it opens. When the exit is open, the house has no timer: you can leave the map and keep the result of the match |
| Above a chest | the amount inside |
| Timers | “Merge in: N”, “Exiting in N...”, the freeze seconds on a frozen bubble |
Mass melts away
You lose mass all the time, whether you are moving or standing still.
| mass | loss without food |
|---|---|
| up to 3000 | barely noticeable |
| 4000 | about 50 per second |
| 5000 | about 90 per second |
| 8000 | about 320 per second |
Mass does not turn into CBW: what you leave the map with is the CBW in your bubble, XP and SCORE.
Money in the bubble
The entry you came in with sits in your bubble. When you split, the money is divided between the parts 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. If you are eaten whole, everything drops.
Bots
Bots are controlled by the game. A bot gives you mass, points and XP crumbs. Bots carry no money and do not pick up chests.
When you cannot be eaten
| when | how long |
|---|---|
| after entering the map | 13 seconds |
| after a revival | 5 seconds |
| after returning from the shooting range | 5 seconds |
| after a teleport | a short shield |
| while frozen | 4 seconds, for as long as the ice holds |
