Complete with a 70s rock soundtrack and a mean team of Roller Derby queens, this five-reel, 25-payline online video slot by Microgaming is strong on visuals and audio in addition to offering several lucrative bonus features.
The Roller Derby max base game jackpot stands at 1 000 coins with second prize coming in at 500 coins. In order to qualify for these, Roller Derby players must wager the max bet of 10 coins on all five paylines, although they are free to wager as little as one coin per line for lesser wins. Roller Derby players may also adjust the coin value to anywhere between 0.01 and 1.00 credits.
The Roller Derby Girls and Their Track
The ball-busting track-burning girls of Roller Derby are Jammer, Pivot and Blocker, in red green and black respectively. They are joined on the track by a brave whistle-blowing referee and other Roller Derby symbols include the usual high-rank playing card symbols branded on colourful Roller Derby roller-skate wheels.
The electrifying 70s rock soundtrack is complemented by graphics that recreate the setting of a 70s dance hall with flashing neon lights and the sound of the girls skating by on the track every time the reels spin. As a video slot, Roller Derby also features animations, which include spinning wheels and the rough-and-tumble of the girls as the shoulder each other out of the way.
The Wild Roller Derby Skate
The wild symbol in Roller Derby takes the form of a purple roller skate and is the most valuable symbol in the game, with the jackpot payout of 1 000 coins for five wilds on an active payline. The wild skate also acts as a substitute for all other symbols, except the scatter, to help finish off winning combinations.
Note that only one winning combination – the highest one – is paid out per line in Roller Derby.
Roller Derby Scatter Logo
As with all scatters, the value of the Roller Derby scatter symbol – in the form of the orange Roller Derby logo – is that it does not have to appear on active paylines to pay out. As long as there are two or more Roller Derby scatter symbols anywhere on the reels, a payout will occur.
Additionally, players who land three or more scatters in a single spin will be granted access to the Roller Derby free spins bonus round.
The Roller Derby Free Spins Bonus Round
As mentioned, the appearance of three or more scatters on the reels triggers the Roller Derby free spins bonus round. Players are awarded five free spins, which can be re-triggered if three or more scatters are landed once more during the free spins. These additional free spins are added to the existing total and can theoretically keep increasing indefinitely.
During the free spins bonus rounds, the Roller Derby girls act as wilds to substitute almost all other symbols – apart from the scatters – to add to the likelihood of winning Roller Derby combinations being completed.
