We love mobile slots too! We selected the best after many hours of playing them.
There are many genres of slots ranging from Ancient, Mythological, Movies, Songs, Books, Western, Safari to Science fiction.

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.


 – In the TOP 5 UK slots, several factors are considered, not influenced by personal preferences. The number of daily active players for the selected slot game at various online casinos. The age of the slot game and its performance over time. Positive reviews and player experiences from trusted sources

Honourable mentions section includes slot games we like to play or were recommended to us by visiting players.

– The online casinos under the “Play Online” option are selected by reputation by the team after a long period of playtesting (in some cases years). We love secure casinos with integrity, good customer support and regular fresh content, or as we call them, casinos with signs of life. 

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. 

As of 2019, the most commonly accepted RTP rate is around 95-96%.
