This is to explain how the new agarserv’s feature, black holes, work.
A player can randomly (if the server creator choose to use those) find black holes on the map. Those are black circles.
If an user cell is bigger than a black hole, all users’ cells are moved to a random location. They are moved, not teleported.
This means that if, while cells are moving from point A to point B on the map, those encounter a virus they will explode (or eat the virus depending of how many cells the player has); also, if playes cells encounter other’s players cell during the transfer, cells can absorb or be absorbed depending on the cell mass.
Last information. All cells are moved to the same exact random point on the map. So if cells are ready to rejoin when moved they will instantly rejoin at the end of the transfer.
