A free spin is essentially an offer that a casino gives to its players to spin the reels free of charge and have the opportunity to win real cash. The free spins may be given to both new and current customers, and it's one way to reward and encourage them to continue betting.
Jamaica is world-famous not only for its musical tradition but also for the world-class rum it exports. Jamaican casinos serve only foreigners and are strictly regulated. In practice, this means that locally licensed online and mobile casinos are not available for locals. However, many international mobile casinos do accept players from Jamaica.
