Playing online slots brings pure enjoyment as it's a mixture of risk-taking, strategy and winning money. Different players pay attention to different aspects of a slot – some of them like playing the Bonus Games, some prefer spinning the reels of more classic slots such as Black Horse, Super Hot or Hot 777,  others love slots packed with special features. One is for sure – every slot player aims to win big. While searching an online slot with a high win rating, one has to pay attention to such a term as Return To Player (RTP) ratio. This term is used in casinos to describe the percentage of the wagered money a slot will pay back to a player over time. The rule is simple: the higher the RTP, the better the payout is.
