Theme and Design 

When you start playing the Bigger Bonanza Rush Express demo, you will immediately feel that you are somewhere back in time, during the 1848 California Gold Rush, just as the title suggests. 

The game's background features tall mountains that cover a golden, dusky sky almost entirely. Inside the red rock mountains, you can see a light tunnel through which a vintage cargo train is passing. The track is built on a high bridge. The symbols are all inspired by the gold mining theme, which is why you will see gems, gold ingots, nuggets, and others. 

The soundtrack is somewhat with the same vibe as the graphics, in the sense that it does give your ears the calm, relaxing feeling that country music can give you sometimes. Further on, you will be able to read the technical details of this slot.
