US games developer WMS has launched a new historically-themed online slot titled Roman Chariots which features three additional reels over the usual display, a supercharged reels innovation and stacked wilds.
Spinning successive wins increases the multiplier on the small set of reels and mirrors the stacked wilds. When the Free Spins symbol appear on the fifth reel of the main set, the lucky punter is awarded five free games to use across all three of the smaller reels.
