Before any Bier Haus spin starts, a run of neighbouring positions on each of the 5 reels is swapped for paytable symbols. A Gold Feature scatter in a trigger turns into a Persisting Wild that holds its spot for the whole free spins round, and on spin 226 that lock came with 15 spins.
It is from Light & Wonder that Bier Haus originates. The studio's catalogue also includes Heidi's Bier Haus, which shares the beer-hall theme, and Dragon Spin.
It's still about activating free spins, however, which landed three times in 350 spins in my session. I played at a stake of 0.40 from a starting balance of 1,000.00. That was far from being a breeze, though. The first feature came on spin 24, the second 202 spins later on spin 226, and the third 107 spins after that on spin 333.
Across 5 reels, combos are possible left to right on adjacent reels from the first reel forward. Wins on multiple paylines are added together, so one base-game spin can collect from several lines at once.


Bier Haus' paytable contains a wild and two scatters, and the Wild substitutes any symbol except the Feature and Gold Feature scatters. A Wild Feature, which only appears during free spins, substitutes for all symbols.
Bier Haus' features are the very core of simplicity, and they might not seem amazing on paper. Of my 350 spins, 109 paid something, and 55 of those paid less than the 0.40 stake.
Central to the base game is the randomly swapped positions, which show on all 5 reels. The longest run without a win in my session lasted 13 spins and ended on spin 86. Before the reels spin, a quantity of adjacent positions there are swapped with paytable symbols. The same replacement also happens on the alternate set of reels the game uses during free spins.
The following feature is triggered by the Feature and Gold Feature scatters. The bet per line and the active paylines stay the same as on the spin that triggered it. 5 on adjacent reels from the left award 5 free spins, and each one extra adds 5, up to 80. My first trigger, on spin 24, came from 6 Feature symbols and gave 10 free spins that paid 13.20, or 33.0x the stake. When free spins start, each activating Gold Feature changes into a Persisting Wild, and it stays fixed in position for the length of the bonus. On spin 226, 7 Feature symbols including one Gold gave 15 free spins with one Persisting Wild locked in, and that feature paid 17.20, or 43.0x the stake. Extra free spins are added to the remaining total if 5 or more Feature, Gold Feature or Wild Feature symbols land on adjacent reels from the left. The third feature, on spin 333, retriggered and paid 10.40, or 26.0x the stake.
The Minty Breakdown: The base game might appear dull. Over 350 spins I wagered 140.00 and won back 112.32, a session return of 80.2%, and the three features supplied 40.80 of that, or 36% of everything won.
