I have seen some people restart the round very quickly, how do I do that?

I think they pres F5 (refresh the page) . But I'm not really sure

press alt and r at the same time

When I do alt r, the page reloads but scrolls all the way to the bottom.

uhm weird the page should not reload, just the map should reset, what browser are you using?

make sure to have the game focused

dha i am use google chrome but my computer is a chromebook so that might have something to do with it
