How to play free slot machines online

Learn how to get started with online slot machines in a few easy steps:

  2. 2
    In the game, check out the paytable to find out each symbol's value.
  3. 3
    Choose the amount you want to bet and how many paylines you want to play. The "max bet" button selects them all.
  4. 4
    Click or touch "spin" to spin the reels. Your winnings are displayed every time you're successful.

Our top tips and tricks to playing free slots games

Although slots is a game of luck, we do have some handy tips and tricks to make playing that bit more fun. Try these tips for yourself and see:

  1. 1

    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.
  3. 3

    Set a timer to stay alert

    Playing slots for too long can make you tired and less focused. To make the most of the game and enjoy it - because after all, gaming is purely about the fun - take regular breaks.
  4. 4

    Try out bonus rounds

    There are thousands of slots on the market, and nearly all of them have exciting bonus rounds to try out. Load up a title you’ve not played before and make your way to the bonus round for free spins and extra fun.
Expert advice

"There’s a common myth that online slots come with hot and cold streaks. This is absolutely not true. All online slots are built with random number generators (RNGs) which means the outcome of every spin is completely unique. "

Free slots vs real money games

While with free slot machines you can hone your skills and perfect your strategy, you can't win any money. Real money slot machines can sometimes offer life-changing sums of money to players, and even the smaller winnings can intensify the excitement. If you're unsure whether you'd like to try real money slot machines or stick with playing free casino slot games, we've detailed the benefits of both in the table below:
