  • RTP - Return to Player The higher - the more profitable
  • Volatility: indicates how often and how much the machine pays (low = common but low; high = rare but large)
  • Bonuses: freespins, multipliers, wild symbols (Wild), scatters (Scatter), mini-games
Slot types:
  • Classic - simple and straightforward, often on 3 drums
  • Video slots - with animations, sounds and many features
  • Progressive - with accumulative jackpots
  • Mobile - adapted for smartphones and tablets
How to choose a slot:
  • Determine if you like classics or modern games
  • Check RTP and volatility
  • Check out the bonus features
  • Try demo mode if available

As well as being a way to try your luck, slots are fun. And if you approach the choice wisely, you can significantly increase the chances of a pleasant game.
