Heidi and Hannah's Bier Haus is a six-reel video slot from WMS Gaming built around an Oktoberfest-style beer hall theme. The game uses 50 fixed paylines and a paytable that awards wins for three, four, five or six matching symbols across adjacent reels from left to right. The reel set is framed by cartoon artwork, beer garden scenery and themed symbols including beer mugs, pretzels, traditional dress and card-suit icons adapted to the Bavarian setting.
The feature set includes Wild Reels, where one or more reels may turn wild on a spin, and a Free Spins round triggered by scatter symbols appearing from the leftmost reel. The bonus rules shown in the help screens indicate that up to 100 free spins can be awarded, with sticky wilds available during the feature. These mechanics are presented in the demo version, allowing players to play for free and practice before playing for real money.
The interface also includes bet controls, a spin button and paytable information for checking symbol values and feature conditions. Standard slot rules apply, including line wins paid on the highest combination and multiple line wins added together. This makes the game easy to review in the free demo while assessing how the base game and bonus rounds behave.
