Mode: Teams

Teams mode is one of the 2 currently available game modes in Agar.io

In this mode you are randomly added to one of the 3 teams which are blue, green and red.

Your objective is to work together with your team and dominate the map by defeating the other 2 teams which are hostile to you.

In Teams mode you cannot eat your own team mates and you can't go through them either.

Skins don't work in this game mode but there are different shades of blue/red/green so that there's a slight customization.

Strategy:

It's a good idea to stay around your teammates, especially when you are small. You can exchange mass in times of need to avoid being consumed or to consume opponents. Keep in mind that teammates' cells cannot eat each other, so try and avoid blocking your team's movements. Cells CAN go through each other, but this does not happen very often.

If an enemy team has over 75% of the mass controlled, you should consider trying to ally with the other minority team. Once a team has the majority of mass under their control, it is difficult to make a comeback. In several instances, one team has completely wiped out the other teams, controlling 99-100% of the mass. You should still be cautious around the "ally" team, just try and avoid conflict if possible. Should you choose to eat the other minority team, you'll improve your own team's chances of success but you'll also be putting all your eggs in one basket. If the majority enemy team consumes your team's largest cells that ate the minority enemy team, defeat is assured.
