Types of Slots

Up until a couple of years ago, slot games only had one payline – right in the middle of the screen. But online casinos started featuring games with multiple winning combinations, and 15 line slots are among the most popular ones.

There is a couple of types of 15 line slot games:

  • Classic games – time-tested games with classic themes 
  • Video slots – these are the modern 15 line slots with excellent themes and fantastic gameplay
  • Based on the game provider – 15 line slot games can also be divided based on the provider. Some of the most notable brands here are Microgaming, RTG, and Playtech.
  • Progressive and standard – slots can be progressive and standard depending on the jackpot. If the jackpot keeps rising as players feed the game, then the slot is progressive. On the flip side, if the jackpot has a fixed winning sum, then it is standard.

If you are wondering whether these slot games feature bonus modes, free spins, or if there are any free slot games to try out – it all depends on the online casino and the provider. These features vary from one site to another, so you might want to set your preferences and do some research before choosing the best online casino to play at.
