A Microgaming classic 3 Reel, single payline, slot machine, Rock The Boat Slots is a good-looking, Elvis-themed slot machine with no Scatters or Multi-Spin. It does however have a wild multiplier symbol, the Elvis, with a 2x or 4x multiplier.
The min coin size is quite low at $0.25, making this a good game for those on a lower budget, plus there's no benefit in playing with more than one coin.
