Our review team looks at a number of elements including licensing and regulation, welcome bonuses, games and software, responsible gambling, and payment options. But there are some additional considerations to bear in mind when choosing the titles to try and bet your cash on. These are listed below.
- Software Provider: We look at the software providers used at the best UK online slots sites as well as the number of gaming options available. Most of the new UK online slots sites offer titles from multiple software developers so if you have a favourite we recommend you start there.

- RTP & Volatility: RTP stands for return to players and is the average amount that will be paid out over time. The recommended ones will have a RTP percentage of 96% or higher. The higher the RTP percentage the better the odds of winning. Volatility often called variance is another element of players should be aware of. Volatility comes in low, medium, and high and they denote the frequency of payouts players can expect. Low variance means the slot will pay out in small regular amounts. High variance slots games payout less frequently but when they do the payouts are much larger.
- Maximum Payout: The maximum payout amount is important if you want to win large cash prizes. This tell you what the maximum jackpot is on the slot machine.
