Since Diep.io's conception, tanks have been wondering about how to communicate with other tanks. Here is a brief collection of signals in use and others created to promote standardizing the signals made by players.
- Spin = Team up/excitement
- Shake Barrel while not shooting = Team, but I'm busy right now.
- Spin = Team up
- Spin Vigorously = Team and/or congratulate
Smasher Branch or Other Tanks Without Manual Spin
- Move left right, up and down quickly = Team up
- Bump into your friend/future teammate three times in a row = Team up
