Unlimited number of teams each with two members…each team has a total of 4 cups, 2 per team member…fill the cups to a desired amount (dont try to be a hero)….decide with ur team member who will be going first and who will be going second. the first player must drink their first beer and flip it over like normal flip cup rules require. once that cup has been flipped successfully they must drink their second beer and flip that cup ON TOP of the first one.. at this point, player two can start drinking their beer and then flip their first cup (third overall) ON TOP of the stacked first and second cups.. once done with that, they drink their final cup and flip that one on top the stack of three…then repeat 3 more times for a total of 4 rounds.. first to complete wins!!!good luck and dont get frustrated, game only gets better as you improve. Just remember, at one time u sucked at normal flip cup too. and hey, ur looking for something new, challenging, and most importantly to get u fucked up… perfect for pre-ing or if ur an alcoholic, all nite partying…..BEERS IN
