Like all casino games, slots have to be random, or there’s just no point playing them. The bit of the slots software that produces the randomness is called a random number generator or RNG. It’s like a digital version of a roulette wheel or roll of the dice, making sure that online slots are both impossible to predict, and fair. The software is checked by gaming regulators or auditors before it is allowed to be released to the public, and checked again regularly to ensure it is working and paying out as it should. We’ve reviewed the best UK slot sites and the best online slots you can play at them, ranking licensed sites by slot range, bonuses, and payout speed. Every site here is UK Gambling Commission licensed and regulated, and we explain how we picked them so you can find the right slot site for you.

A wide range between the smallest and largest prize on offer usually means the bonus feature is rather volatile. It has three reels, five paylines, and a re-spin feature that locks winning symbols in place.
