the game players agree to start a new game, as the colors on this one are too similar and we can't see who's who.
There is an option called "terminate game" - to the right of that you have [vote] . If you all vote to terminate the game is ended with no winner and no loser.
I think you need to be on the game page, not the player page. If that's not clear, paste a link to your game and we can help you straighten it out.
