UK Online Slots 

Since the 1990s, slot machines have been a mainstay at online casinos and are the most popular games at any casino. Slot games have evolved from simple 3-reel, fruit machines to highly advanced slot adventures with highly innovative specialised features, exceptional graphics and fantastic gameplay. There are thousands of online slots boasting a diverse range of topics, themes, cutting-edge graphics and optimum sound quality. There are all types of slots at online casinos today, with anything from high payout progressive jackpots, to the humble 3-reel classic slot. 

Different Types Of Online Slots Games

3-Reel Slots

Slots are rather like video games due to their features, yet there are straightforward classic 3-reel slots that are based on traditional slot machines with bells, sevens, fruit and bar symbols. They offer a more stripped-down gaming experience with fewer features and bonus rounds. The gameplay involves spinning the reels to get identical symbols on the pay lines. 3-reel slots machines tend to provide superior odds, and they are cheaper to play due to fewer pay lines and reels. 

5-Reel Slots

5-Reel slots are by far the most I demand games at online casinos. They stand out with engaging themes, special features, free spins and mini bonus games. You generally get from 10 to 30 pay lines, entertaining graphics and animations, arcade-style bonus rounds, and mini bonus games. 5-reel slots tend to include Wild symbols, that serve to replace standard icons to create wins. 

Progressive Jackpot Slots

Progressive jackpot slots offer very high payouts and have incremental jackpots that increase as more people play the game. There are stand-alone jackpots and networked progressive jackpots. The latter is shared with online casinos. These games take a tiny percentage of every player’s bets, placing them in a shared pool, which can bloat to an extremely high amount. 

Bonus buy-in slots

A new trend currently sweeping through online casinos is bonus buy-ins, whereby players can purchase the bonus games or a few spins. Such a feature has become useful with higher volatility slots allowing players to bypass standard play and move straight to the bonus features where the payout rate is better. The cost of buying-in is expressed as a multiplier of your stake, and you can choose from various amounts of free spins perhaps in rounds of 6, 8, or 12.

What is Slots RTP% & What are The Highest Paying Slots?

All Slot games have an RTP percentage that shows how much the game pays back over time. It mostly shows you the house advantage and how much money the slot takes in. The higher the RTP, the better the slot pays. You should look for slots with an RTP of over 96%. If the RTP is below 92%, it is considered on the lower side, and the average is around 94% to 95%. Slots with RTP percentages exceeding 97% are considered excellent, while over 98% is phenomenal. The UK best slots with high RTPs include the following. 

Mega Joker by NetEnt has a superb RTP of 99.00%. When playing with maximum betting limits, your wins are transferred to the Supermeter. That permits you to cash out, and press Collect or play on and press the Spin button.
