What are online slots?

Online slots are the modern version of the physical slot machines you've seen in brick-and-mortar casinos. They are the most popular gambling games online and all UK-licensed internet casinos have them.

How to play slots?

The reels start to spin together and stop one by one. Whether you win or lose depends on symbols you land on the reels and the active paylines of the game.

How do online slots work?

Slots are built so that each result is completely independent from the previous rounds. Slot games are powered by a random number generator (RNG). They make sure the results of each round are 100% random and unpredictable.

Licensed slot suppliers need to have their games tested by independent testing laboratories.

How to win at slots online?

To put it bluntly, there's no way to beat a slot machine. You can win, but it's all down to blind luck and there's nothing you can do about it.

Some players believe they can determine when a slot is going to pay out or use different betting strategies to maximise their chances of winning. However, the slot machines have no memory and the odds stay the same from one spin to the next, even after a jackpot is won.

Instead, you can enjoy slots for a longer time without losing too much by managing your money well in an online casino:

What is RTP in slots?

RTP or Return to Player is the payout percentage of the slot. Slots available in UK-licensed online casinos usually have an RTP of around 96%.

EXAMPLE: In a slot with an RTP of 96%, on average you win back £96 for every £100 wagered.

The RTP is an average that realises over the course of thousands of spins, meaning you probably won't win exactly £96 within a single game session.

RTP can also be used to calculate the house edge, i.e. what are the odds in casino's favour. 100% - RTP% = house edge. In the example above, the house edge is 4%.

What are the best online slots to play?
