In terms of gameplay, there could not be an easier and less engaging game than slots. The only thing you need to do before you start playing is to set the number of lines to play and the bet per line. 
Then all you have to do is press the ‘Spin’ button or choose the ‘Autoplay’ option for up to 100 lines or until feature. Roulette can also be considered a fairly simple game, but with Video Poker or Blackjack, a more strategic thinking is needed to choose the course of the game, which can make the difference between a win and a loss.
The indisputable advantage of playing online slots is the opportunity of hitting a huge jackpot, which can even reach millions, as opposed to the classic casino games like blackjack or roulette. While playing slots, the entertainment is guaranteed not by challenging gameplay and strategic thinking, but by means of great graphics and sound effects. Also, video slots often include great animations, videos and interesting bonus rounds. Lots of new and innovative online reels can be found at new online casinos, who often team up with newbie software developer companies. These devs typically have their finger on the pulse of the online gaming industry and create cutting-edge slots products with excellent graphics, storytelling and features.
Slots however also have few drawbacks, when compared to the classic casino games. There are no live versions of this game, although Evolution Gaming have already experimented with the idea. Also, the potential addiction is higher with slots than the other games.
Few players acknowledge the importance of the RTP (return to player) when playing slots. However, it determines how much of your investment will be returned to you, under ideal circumstances. Online slots usually have an RTP of over 90%, but only some of the best slot payouts will reach more than 95%.
It is also important to remember that the RTP is slightly lower for jackpot slots. The lower payout rate is due to the fact that part of the money you wager go into the jackpot. And given as jackpots are different sizes and different percentages of them can be won, the expected profit may vary.
