It's the age old game of pushing a beer mug to the edge of the bar thingie thing. How good is ur judgement? Can u judge the right amount of swipe needed to get that mug over the red line, but not over the edge?
This is a game of skill and a game of judgement. Best achieved while sober, regardless of how many beer mugs u may be swiping!
