Steampunk is a genre that is inspired by 19th century industrial equipment, particularly steam powered machinery. The imaginative fantasy using steam punk designs have been set in environments like the future or the American Wild West among others. Victorian novelist like Wells and Verne made full use of this genre in their sci-fi writings. Steampunk has also been used in architecture, art, fashion and online slots.
One such popular video slot is Steam Tower from the leading software provider NetEnt. It is live at online casinos
like InterCasino and Golden Palace. There is a medieval tale leading up to the slots play. A fair princess is locked by an evil dragon in the 16th floor of a tower. You have to assist her lover in rescuing her. Steam Tower has the standard 5 reels and 3 rows structure with 15 fixed paylines. The reels are set at the bottom of the steam tower to start with, but ascend the tower as the game progresses. The background retro pulsating music creates a tempo suited for the rescue theme.
The high paying symbols are the dragon’s eye, the lover in Victorian attire, the princes and the top of the steam tower. The dragon eye awards the highest line payout of 2000 coins for five symbols in an active payline. This indicates medium volatility in the online slot. The low paying symbols are the playing card icons from J to A with a mechanism of cogs and gears in the background. The grapnel used to climb the steam tower is the wild symbol. A full length image of the lover expanded three high also acts as a wild symbol.
The rescue story moves forward through the free spins feature. This is triggered when the expanded wild symbol appears completely on the reels in the main game. The reel set moves to the next floor of the steam tower and the 10 free spins start. Every time a grapnel wild symbol appears on the reels during the free spins, you are awarded two additional free spins. The free spins come with a payout multiplier that depends on which floor of the steam tower you are on. It is 2x for the 1st floor and 7x for the 16th floor. Meters on the reels display the current floor and multiplier. When you reach the 16th floor you the lover rescues the princess and you win a bonus of 1000 coins.
