Steam punk is an interesting genre. It features archaic Victorian technology portrayed in an almost irreverent manner. Some of the Microgaming video slots with this theme draw good traffic at online casinos like Jackpot City, Royal Vegas and Roxy Palace. Therefore the leading software provider has announced a new online slot titled Fortunium with this theme. Meanwhile players can check out the steam punk genre on the existing slot machines.

Steam Punk Heroes is set in a derelict factory. The background audio and the artwork match the theme. The Wild logo is the wild symbol that doubles payouts when substituting in winning combinations. The symbol also awards the highest line payouts. The game logo is the scatter symbol and awards payouts multiplied by the total bet. The unusual set of high symbols includes steam punk lady, lion and air carriage. The low symbols are the usual playing card icons.

Landing three or more scatter symbols triggers the bonus feature. You are first taken to a second screen that displays two gears. You pull a handle to operate the gears. When they stop rotating the free spins parameters are revealed. The right gear indicates the number of free spins and the left gear the payout multiplier. Steam Punk Heroes has 5 reels and 3 rows with 25 selectable paylines.

Phantom Cash online slot has a ghost busting theme that goes well with the eerie environment of the steam punk genre. The ghostbusters in the slot game are named Thurmingham and Carstairs. Both are wild symbols that double payouts when substituting in winning combinations. Thurmingham appears only on reel 1 and Carstairs appears only on reel 5. The high symbols are the four ghosts. The low symbols are the usual Microgaming playing card icons. The scatter symbol is the haunted house that awards payouts multiplied by the total bet.

The free spins feature is triggered by landing three haunted house symbols anywhere on the reels. A ghost meter is displayed on the screen with an initial value of 8. Thurmingham and Carstairs capture any of the ghosts that appear in the same row as them in any free spin. You will be awarded a random bonus prize for each ghost caught and the ghost meter reading will be appropriately reduced. Landing three scatter symbols during the free spins increases the ghost meter reading by 8. The free spins continue in this manner till the ghost meter reading is zero. Phantom Cash has 5 reels and 3 rows with 25 fixed paylines.
