It’s easy.
1. While on the game, tap the gear icon at the upper-left corner of the screen.
2. Under the Basics tab, tap on the “Initiate a surrender vote”.
The surrender option is enabled after six minutes. At least four must agree to end the game. Otherwise, it will be available again after a minute.
