   Read up on the paytable

   Before you start playing make sure you study the paytable so you know which symbols are which. Watching the reels spin is so much more fun when you know which symbols you’re hoping to hit.
2. 2

   Practice on the classics

   If you’re wanting to get familiar with slots games, keep it simple and stick to the classics. The more traditional slot games are generally easier to follow and can help you learn the ropes before you add in extra bonus rounds.
