Heidi’s Bier Haus is a 6 reel, 50 payline slot from WMS Gaming that can be played on desktop, mobile and tablet devices from 75p to £45 per spin. The 2nd Bier Haus slot from WMS, you will benefit from random wild reels, Heidi’s Wheel Bonus where you can get persisting wilds, added Hans wilds or extra free spins in the Free Spins Bonus feature.

I must say that Heidi’s Bier Haus is best played in portrait mode on your smartphone or tablet device. Anyway, it has an Oktoberfest theme with the beautiful blonde and buxom waitress overseeing proceedings. With beer pumps over all reels, symbols include diamonds, clubs, hearts and spades as well as pretzels, traditional Austrian hats, trumpets, accordions, steins (beer flasks), low German houses (known as Fachhallenhaus) and Hans.

The pint of beer is the wild symbol are substitutes for all symbols except the Green, Purple and Red Heidi – Red Heidi will only appear on the 4th reel whilst reel 6 contains only wild (pint of beer), Hans, Green Heidi and Purple Heidi symbols.

Prior to a reel spin, a number of positions on reels 1 through 5 are randomly replaces with other symbols except Club and Red Heidi. Now, the Tapper feature can be randomly triggered giving you between 1 and 6 reels to become fully wild! The wild reels are wild for all symbols except the Green, Purple and Red Heidi symbols.

The other main attraction is the Free Spins Bonus feature which is triggered when 5 or more scattered Green, Purple or Red Heidi symbols appear on adjacent reels beginning from reel 1. The Green, Purple, Red Heidis will award between 5 and 100 free spins depending on the number shown.

Now, if you landed a Red Heidi to trigger the feature, you will get a spin of Heidi’s Wheel Bonus – if you land of Heidi, Hans, Accordion or Pretzel, you will win the corresponding jackpot shown above the reel set as well as 1 more spin of the wheel. The most valuable jackpot is Heidi which gives you 5,333 times your total stake! You can also land on the Beer which will give you 3 wild Hans free spins (more details below). The other option is the Extra Spins which gives you 5, 7 or 10 more free spins.

For every Purple Heidi that trigger the feature, you will get a persisting wild that remains locked in position for the duration of the feature. During the feature, the Tapper feature can trigger at random with up to 6 reels turning fully wild – you can also play a Wild Hans spin randomly where between 4 and 10 Hans wilds are added to the reels. Finally, you can also retrigger the feature giving you even more free spins.

Heidi’s Bier Haus is definitely different in terms of how it looks and plays – I think it works rather well. In terms of variance, I found it to be medium to high variance with the bigger wins coming in both the base game and Free Spins Bonus feature. Getting up to 6 wild reels randomly is the key to winning big but it’s highly unlikely.

The fixed Heidi jackpot offers the biggest reward and, yet again, is highly unlikely. I’ve found my biggest results have been from getting a few Persisting Wilds and a few random wild reels. I do love the fact that Heidi pulls the lever and fills a reel with beer to give you a wild reel.

Overall, I like the fact it’s different and it has the potential to give you huge rewards – you just need patience and to hope Heidi serves them beer wild reels. I also recommend you try Bier Haus, the original, which is a lot simpler.
