How to Pick the Best Slots

Picking the best online slots casinos in the UK is hard work, which is why we've done it for you. We've spent many hours researching and providing you with accurate information and reviews of ‘best online slots casinos’ around the Web. To help us do this, we've developed and improved our own ratings system. This system is based on criteria casinos need to meet before we recommend them to you. Here are just some of the factors in our criteria. 

Return to Player

One of the smartest ways to pick winning slots is by checking the Return to Player (RTP) percentage — a key metric that shows how much a slot pays back over time. While average RTPs sit around 96%, some physical slot machines at brick-and-mortar casinos drop as low as 88%, while the highest-paying ones can hit 99%. To boost your odds, stick to online casinos with the highest slot payouts, where top RTP slots are more common and better promoted.

Safety and Security

Safety and security are about making sure that your personal and financial data remains safe. The first thing we check is a casino’s legitimacy by looking for a valid licence. Possession of a licence from the UK Gambling Commission tells us that the site is regulated by an official authority. We also want to know whether or not it’s regulated by an independent testing agency like eCOGRA. We look for an up-to-date SSL encryption certificate, which is important for a safe online slot experience, as it protects your personal data.

A Large Slots Selection

A good selection of slot games is essential for any top slots casino. The games library should include progressive jackpot slots, for example. These games pay out huge winnings, so they can be exciting to slot players. The option to try out games for free is another feature we look for, as being able to sample a casino and its games before you play for real money is a huge plus. Slot games are typically developed by specialist casino game developers like Microgaming and NetEnt. Typically, if a casino offers games from the best developers in the business, it means that this gaming website is professional enough and aims to provide an entertaining gaming experience to its players.

Bonuses and Promotions

Bonuses and promotions that are fair and provide our players with good value are next on our list. A generous welcome offer makes for a great start to any online slots casino. Bonuses that check the box for us include deposit bonuses, slots sign up bonus no deposit offers, free spins, and cashback offers. We also insist on reasonable terms and conditions for us to consider a slots bonus to be fair.
