In pouring simulators, tilting your virtual glass precisely at 45 degrees the microsecond the beer hits the glass maximizes score multipliers.
The game’s collision detection registers the initial taps as "pre-wetting" the glass, which tricks the foam algorithm into thinking you performed a professional side-pour. You will skip the "violent foam" penalty entirely.
Keep an eye out for the number 1842 (the year the world's first pale lager was brewed). Entering this number or clicking on elements flashing this date often unlocks hidden skins or bonus points.
