The winner will receive what their opponent wagered, as well as keeping the items they wagered. A coin will then be tossed and will land on one of two symbols. From here, simply select the Counter-Strike: Global Offensive items or VGO skins you wish to gamble. Once you’ve navigated to the coinflip games, you can then challenge a member who’s in the lobby.
