How to win

Description of Mystery at the Mansion slot machine

Starting the video 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 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 molding on a high ceiling, an unusual ornament that runs up the columns and the floor of an expensive tree. And only the multicolored symbols of pay lines a little revive the sinister situation. Net Entertainment developers are able to create original video slots, so effective and realistic. Sound effects fit perfectly into the design of the video slot. Disturbing musical lilt, interrupted thunder, dull alarm and drifting far away screams of terror keep the gambler in constant tension.
