Bierhaus: My Opinion
The keys to the game are the fact it has stacked wilds (and other symbols) plus you can get up to 80 free games with a few sticky wilds thrown in for good measure if you are lucky. Watch the video and you'll see me trigger 10 free spins with 2 sticky wilds (these crop up when the purple Frauleins appear in the triggering pattern).
You do have to get these Fraulein triggers from left to right on the reels, and you need 5 or more to start the free spins. For every extra Fraulein trigger over 5, you get 5 more free spins.
I've not yet hit anything more than 100x on Bierhaus - yet - but it's a game that keeps you immersed more than many other recent slot games. It's one of those where the balance between entertainment and winning is close to what you want. Not as perfect as on Thunderstruck by Microgaming or Great Blue by Playtech or even the aforementioned Colossal Reels games Spartacus and Kiss but Bierhaus is close. If only it ran a bit faster.
