Heidis Bierhaus is a video slot experience created by the provider Williams Interactive. In this Heidis Bierhaus slot review you’ll learn about its core features (including RTP, max win, and volatility), the bonus mechanics, and what helps the game stand out — along with the areas where it may fall short.
Heidis Bierhaus is played on a 6 reel layout with up to 25 paylines/ways. The game includes a variety of features such as Extra Spins, Jackpot, Retrigger, Stacked Symbols, Stacked Wilds, Sticky Wilds, and more. There’s also a dedicated free spins bonus round, which is typically where the game’s biggest win potential comes into play.
The standard RTP (Return to Player) for Heidis Bierhaus slot is 96.13% (Could be lower on some sites). This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96.13. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 150x your total bet which is rather low and can not give you the really big wins but often have a higher frequency of small wins instead. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
