Description of Mystery at the Mansion slot machine

Triggering the slot, you will immediately find yourself in one of the rooms of the mysterious mansion. No ray of sunlight breaks through the massive curtains, and the whole environment is lit with chandeliers and a few reflections of the almost extinct fire. Bordeaux-brown shades, taken as the basis for the design of the slot machine, further increase the atmosphere.

But even in such a light, the elegant decoration of the old room is well discernible-gilt stucco moulding on a high ceiling, an unusual ornament that runs up the columns and the floor of an expensive tree. Sound effects fit perfectly into the design of the slot. Disturbing musical lilt, interrupted thunder, dull alarm and drifting far away screams of terror keep the gambler in constant tension.
