 Finding the best online UK casino is often a time-consuming task and there is no direct answer to it. There are several things to consider when looking for the best casino. Like with most things, online casinos too have positive and negative sides.

The number one priority always should be security. Fast and easy payment processing, confidentiality and above-average customer support. Multiple deposit methods and fast processed withdrawal methods are a must-have for every respectable casino.

Winning big is the main goal when gambling at any casino. Bonuses, rewards and prizes are surprisingly important when nominating the best casino. Slot players from the United Kingdom have a big advantage here, as they benefit from the most generous and fair welcome and deposit bonuses.

The number of casinos worthy of “The Best” title grows larger every year. The casinos reviewed by us here at UK Slots are superior quality and tested by our staff. Two casinos stand out, namely Ahti Games and Casino Gods that offer high-quality services.


RTP (Return To Player) and RNG (Random Number Generation) are the slot players best friend. Whenever a win happens at a slot machine it is decided by those two factors. Playing high RTP slot games does mean a higher chance to win! Below are the best paying slot games with at least 98.5% RTP or higher!


– Most of the times bonuses don’t meet the expectations. The reason for this is the sneaky (to say the least) bonus terms and wagering requirements. For example, a first deposit 100% match up to £100 bonus means £200 to play with for the player, right? Well not exactly. To clear the said bonus, a wagering requirement must be met, that can be 40x the bonus or higher. this means the player must bet £4000 to clear the bonus. Usually the bigger the bonus, the bigger the wagering requirement.

– Luckily no two casinos are the same, and as long there is competition in gambling better, fairer bonuses will continue to pop out. It is possible to play no wager slots in the UK. The player’s money is not locked, meaning withdrawals are possible at any given time. The rewards can vary from free spins, daily tournaments to special events.


Are you a new player? This 2-minute read will hopefully save you a lot of time and money! Choosing the best slot site can often be difficult and misleading due to the deposit bonuses which most of the time are impossible to claim due to high wagering requirements. The best solution is to ignore bonuses and focus on your interests, and what you are hoping to achieve.

  • Trust and safety should be a priority. The age of a casino and positive feedback from players are usually signs that the casino can be trusted.
  • Customer support reaction time. How fast your questions are answered translates to how seriously you are being treated. The best online casinos have great live support.
  • Services offered. Some sites offer free games, free tournaments. Playing for fun is fine. If fun can be free its even better!
  • RTP. The RTP (Return To Player) rates can vary. It’s no secret that higher the RTP the higher the winnings.
  • Finding your favourite slot game is easier than ever before. The same game providers are usually partnered with multiple online casinos. For example, a slot game like Rainbow Riches (made by Barcrest) can be available at several different casinos, that have different signup bonuses.


 The biggest wins ever recorder at slots were the jackpot wins. Top slots with jackpot features are not hard to find at all. There are three main jackpot types that a player can find when playing online.

Network-wide jackpots are usually the largest in sum, sometimes millions and available at multiple casinos. The next jackpot type is the fixed jackpot that has a much smaller reward usually in the thousands and can affect many slots at the same time. Progressive jackpot types are the jackpots that keep increasing over time until claimed.

An unmissable feature to look for when playing online slots are the free spins. Who doesn’t love free spins? Free spins allow players to spin without betting and this can feel sometimes like cheating, or getting free stuff. In the best-case scenario, the free spin winnings can end up in thousands.

Popular slot machines also have the Gamble feature, also known as the double-up. The said feature triggers after a winning spin, the player can choose to double or nothing the last win. In this 50-50% chance gamble feature, the player must guess the right colour from two faces down cards. This slot machine gambling is fast, fun and very easy to play!

The power of a cash bonus should not be underestimated! New players can often receive cash bonuses for specific slot games when joining a casino. Having bonus money to play with has several advantages. Getting familiar with a new game, or simply winning more!

New or recently launched casinos have very little chance of being recommended by us.

Depends on the casino. Our team consists of players from Finland, Germany and Great Britain, so we tested from those locations. In some cases, EU countries are accepted depending on the license. 

In recent years slot games have changed a lot. Providers and casinos that were using fake RTP (Return To Player) systems were slowly replaced by fairer ones.
