While slot machines are primarily games of chance, there are strategies you can employ to maximize your potential winnings. Knowing the return-tbest real money slotso-player (RTP) percentage of the slots you decide to play is a good strategy. The RTP shows how much of the money wagered will eventually be returned to players by a slot machine. Long-term player odds are generally better for slots with higher RTP percentages (usually above 95 percent).
