The term “professional gambler” refers to all the players, to whom gambling has become more than just a hobby. In short, these players gamble to make a living. 

The majority of professional players mostly select live dealer games because the chances of winning some considerable amounts increase significantly when one plays against a human dealer instead of a computer. So, the most popular games among these types of players are definitely poker and blackjack.

Why Slots?

However, you can also come across a bunch of seasoned gamblers who engage in computer-controlled casino games. And the majority of them prefer an online casino slot machine over all other computer-controlled games for multiple reasons:

  • The first of them is a progressive jackpot. Some progressive slots (such as the legendary Triple Diamond slots from IGT) tend to increase the RTP percentage along with accretion of the progressive jackpot value. So, by playing these slots, you can end up with a return to player rate that exceeds 100%!
  • Mystery jackpot slots also offer a progressive jackpot which pays at a specifically determined point of the gameplay. However, the main thing about these games is to know when exactly to start playing (adjusting to the current jackpot amount). Some professional players tend to use various mathematical formulas to solve this issue, while others rely on pure experience and evaluation.
  • You can also take advantage of accumulating (banking) slots. They come with a bonus meter you get to fill up by collecting special symbols. Since some players run out of time/money and never get to fill the meter up, you can jump in and start playing. These slots theoretically carry a larger payout percentage when the meter is almost full.
