Mysterious is a slot machine dominated by ghosts, in which the aim is to collect the same symbols on the paylines. The board measures 4x4, meaning that we are able to see 16 symbols at once. According to the description, we are able to win in 4096 different ways, while the point is to get coherent combinations by the end of the rotation, thus by going from left to right, the line of symbols shouldn't get broken.
Forget about the classical slot machines, everything is adjustable in Mysterious! Fast Spin can be activated, which means that the spin time will be reduced. In addition, there is a Battery Save Mode, you may switch the background music on and off, tinker with the Sound Effects setting and the Intro screen may be turned off if required. Your spins are stored under the System Settings menu, where you are able to view your previous game rounds under Game History.
The bet is set at the bottom, under the reels. There is a large circular arrow in the corner to the right which starts the game. Next to this, you have access to the plus and minus buttons to help you determine the amount you would like to risk in a single spin. A small window will pop up, here you may enter the Bet, the Value and the Total Bet.
