The Big 'M' Casino's 186-foot-long ship glides down a scenic coastal river, entertaining gamblers with Las Vegas–style games and filling rumbling bellies with all-you-can-eat buffets. Partake in healthier river gambling with today's Groupon: for $15, you get admission to a casino cruise and an all-you-can-eat buffet, including port tax, aboard The Big 'M' Casino in Little River (up to a $35 value). When river-runners of yesteryear wanted to gamble, they simply took bets on who could noodle the largest catfish or survive the longest without vitamin C.
