There's an option to surrender when only 1 human remains. If it's not set, no can do.
To be honest, there are strong arguments to remove this settings/ always have it be . Since, didn't Fizzer add the option to "finish the game versus AI" when someone surrenders anyway? Thus, the setting is a bit dated and maybe should always be on. [Not that I have tried that function much myself, so maybe I am missing some subtle differences]
