The secret to a Max Score isn't just saving 100 shots; it's saving 20 shots in a row. The game rewards "clean sheets" (no goals allowed). If you concede a goal, your multiplier resets.
This is the great disappointment of the Pilsner Urquell Game. Unlike modern video games, achieving the max score rarely unlocks a secret level or a coupon for free beer. In the original 2010-2012 Flash version, hitting 100 points triggered a golden animation—the mug would glow, and the text "Master of the Tankhouse" would appear. That was it.
However, in limited regional promotions (Czech Republic, Slovakia, Germany), players who screenshot their max score and submitted it to Pilsner Urquell social media campaigns won branded merchandise: steins, bottle openers, and once, a tour of the Plzeň brewery.
