Rich Wilde and the Book of Dead is a classic slot game from Play’n GO where you journey to the sands of Ancient Egypt to uncover the treasures left in the Book of Dead.

This five-reel, three-row slot has a total of 10 adjustable paylines and offers stunning graphics that bring the world of Ancient Egypt to life. 

You can claim 30 extra spins on Book of Dead as part of the welcome bonus with Las Vegas Casino. 

2. Double Bubble

Double Bubble is a fruity slot game from Roxor Gaming that sets itself apart from the pack thanks to its winning potential of x20,000 your stake.

Played across five reels and 20 paylines, players can get stuck into special features such as bubble line, multipliers and a bubble pop bonus game. Five wild symbols provide a x20,000 payout, while the bubble line win on all paylines can multiply to x22. 

Collect three bonus symbols to trigger the pop bonus which gives you a choice of three bubbles sparking random coin multipliers.

The game has a distinctive retro arcade theme to it with bright and colourful graphics, with high volatility and an RTP of 95.48 per cent. 

The Virgin Games sign up bonus offers new players 30 bonus spins for the game Double Bubble on their UK casino site. 

3. Starburst

The Starburst from NetEnt is one of the most popular titles on slot sites that players have been enjoying since 2012. With 96.09 per cent RTP and low volatility, this iconic game has five reels and three rows with 10 paylines that pay out both ways.

Bonus features include wilds that help you form winning combinations by substituting for other paying symbols and whenever a wild lands it will expand to cover the whole reel. Expanding wilds activate free respins which can be triggered up to three times.

The game is aesthetically pleasing too, with five beautifully designed gems coming in their own colours and shapes and two further high-paying symbols - the lucky number seven and the gold BAR.

4. Big Bass Bonanza

Big Bass Bonanza is another classic title from Pragmatic Play where you can fish up big wins on a 5x3 playing grid with 10 paylines where the fisherman is the only one that can collect or bring more fish symbols on the screen.

During the free spins round the fisherman can increase the multiplier up to x10 or activate the dynamite feature which transforms random symbols into fish symbols.

The game RTP is 96.17 per cent and the volatility is medium to high, with the free spins bonus able to be retriggered up to three times. 

MagicRed offers new players 100 bonus spins on Big Bass Bonanza. 

5. Rainbow Riches

Rainbow Riches from Barcrest was released in 2009 and continues to impress players with its vibrant Irish luck theme and a host of features.

Three leprechauns launch the road to riches bonus which changes the scenery and lets you spin the wheel and move up the road collecting win multipliers along the way with the potential to reach a pot of gold worth x500 your bet. 

Three or more wishing well symbols let you select one of the wells to potentially win x2 to x500 your wager, while the pots of gold round offers a maximum win of x500 too.

Rainbow Riches is a medium volatility game with 95 per cent RTP that puts its enduring success down to the engaging bonus gameplay.

6. Big Bass Splash

Another title from Pragmatic Play’s Big Bass series, in Big Bass Splash the game symbols include standard royals such as the likes of a dragonfly, bait box, fishing rod, truck and different size fish which form part of the bonus round.

The two feature symbols are the wild and scatter - the wild is a cheerful bearded fisherman who helps players form wins by substituting for the necessary symbols to complete a combination on different paylines. The scatter is a hooked bass fish jumping out of the water.

With an RTP of 96.17 per cent and high volatility, the monster is the key to unlocking the free spins feature where players could potentially land up to x5,000 their original bet. The other features include increasing multipliers, level up, nudges, retrigger, stacked symbols and more. 

New players at BetMGM can receive 100 bonus spins on Big Bass Splash as part of the welcome bonus for the new UK casino by meeting the sign-up bonus requirements.

7. Fishin’ Frenzy Big Catch: Jackpot King

This instalment in the Fishin’ Frenzy series from Blueprint Gaming sees you collect fisherman to upgrade fish and land extra spins.

Look out for fishermen on every spin as they can help increase your prizes, with four fishermen needed to upgrade the smallest fish to the next fish, as well as giving users five extra spins. 

Collect enough fishermen and you’ll turn every fish into the big catch, meaning every fish landing in view is worth x50 your bet, while the jackpot king feature gives players the opportunity to win cash prizes or one of three progressive jackpots on any spin.

The game has medium volatility with an RTP of 93.85 per cent and pops with a deep blue colour scheme and fun cartoon-style graphics.

8. Secrets of the Phoenix

Secrets of the Phoenix is a Gamesys title where you play with up to 25 paylines in a slot packed full of free spins and stacked wilds, with an RTP of 94.97 per cent and medium volatility.

The raining reels feature, where the winning symbols are removed once they have paid out leaving space for new symbols to fall into, can potentially produce further wins after an initial success. 

If a win causes a whole vertical reel of symbols to disappear it gets replaced with a stacked wild, which means the reel will be treated as one large wild symbol. Then triggering four or more consecutive wins triggers the free spins bonus.

As part of the sign up bonus from Bally Casino, you can get 90 bonus spins on Secrets of the Phoenix Megaways.

9. Monopoly Paradise Mansion

Another Gamesys title, Monopoly Paradise Mansion features two different bonus games and a top prize of x10,000 your stake.

Picking cards in the community chest and property card bonus games gives you the chance to collect cash prizes that are multiplied by the number of win lines that triggered the bonus rounds. 

There are also wild symbols that can replace all other symbols - except bonus or scatters - to complete wins, with five wilds on a single payline paying out the highest prize of x10,000 your coin size.

In total there are up to 20 paylines in this medium variance game with 96.29 per cent RTP and of course, the game is based on the iconic Monopoly board game.

You can get 30 extra spins with Monopoly Casino for Monopoly Paradise Mansion.

10. Fishin’ Frenzy Megaways

Fishin’ Frenzy Megaways is also from Blueprint Gaming and offers gameplay across six reels with a varying number of rows and up to 15,625 possible ways to win. It’s a high volatility game with 96.1 per cent RTP.

As well as more ways to win than the original, there is an additional sixth reel providing more chances to trigger free games. Three or more scatters will trigger the free games round and the more scatters awarded the more free games, allowing you to win up to a possible 50 in total. 

The free games feature has been enhanced to allow more fish and fishermen to be able to land in view, while reels can randomly highlight on any spin and when you light all five you’ll be rewarded with the pick a prize feature. 

Megaways pots can be grabbed from this feature, where the total cash displayed is given as a cash prize, while the gold Megaways pot also awards a repeat chance.

2. Try different types: Explore video, jackpot, and classic slots.

Remember to Gamble Responsibly

Gambling can be addictive and slots can quickly become compulsive if great care is not taken. As such, users of slot games are advised to make use of their responsible gambling tools such as:

• Deposit limits - users have the ability to limit the amount they can deposit
• Reality checks - set up notifications to prompt you to be mindful of how long you've been active
• Time outs - users can self impose a cooling off period if they're concerned about their betting habits

All slot gaming sites regulated by the UK Gambling Commission must give users the option to self-exclude.

The self exclusion tool should be utilised the moment a customer realises their gambling has become problematic. Should you wish to seek help for gambling-related harm, there are several UK charities and institutions you can turn to for support, advice and information:

• GamCare
• GambleAware
• Gamblers Anonymous
• NHS
