Wins are attained by successfully draining your opponent's Life Gauge to 0. The more Life Gauges you drain, the more wins are earned. Once you've reached a new level, you must reset your win counter, and obtain exactly as many wins as the corresponding level requires. It does not add on from previous victories.
