While it is always interesting to explore the latest games, sometimes it’s nice to have a spin on the classic slots that have allowed the industry to grow.
We’re talking about the games that have really made a name for themselves, the ones that instantly come to mind when you think about online slots. Take Rainbow Riches for example, which has been so popular that they now have fully blossomed franchises, with a number of extra games.
Take a look below at a range of our best online slot machines, which have been established by their continued popularity among our players on-site.
One of the best online slot games to play is the classic Rainbow Riches, with many of our players enjoying this particular one. This is the original game that inspired the popular franchise when it was released back in 2006, and you can now find more than 15 different games from the Rainbow Riches series on our site.
Rainbow Riches features up to 20 paylines, and spins are available from just 1p, with an RTP (Return To Player) of 95%. In 2022, we paid out over £30,000,000 to our players in winnings on this online slot.
There are a number of different bonus rounds available in this Irish-themed slot machine, including the Road to Riches feature, where you stand a chance of winning a maximum prize of 500x your wager by progressing along the golden path. The same prize is also up for grabs in the Wishing Well feature, as well as the Pots of Gold feature, meaning there are plenty of opportunities to trigger a big win.
We mentioned that there are plenty of other choices in the Rainbow Riches franchise, and this is just one of them.
In Rainbow Riches: Jackpot O’ Luck, you can enter the Free Spins Bonus by landing at least three Bonus symbols on the reels, and you will then be presented with the choice of 15 barrels, containing a number of free spins, multipliers and jackpot letters.
If you spell out the word ‘jackpot’ from your selection of the barrels, you could activate the progressive jackpot! This prize has a seed value of £50,000 and is available to all players regardless of bet size.
You can spin the reels in this exciting online slot game from as little as 15p, and it has an RTP of 93.99%, as well as a further 0.24% which contributes to the progressive jackpot.
Rainbow Riches: Pick n Mix is one of our favourite instalments from the thrilling slot series. You can place wagers on this game from only 20p, and 20 paylines can be played. This slot falls into the low volatility category, as its RTP ranges from 94% to 98%.
As you can find in some of the other games in the Rainbow Riches slot franchise, there are several bonus rounds for you to try and activate. There is a Free Spins Bonus, with up to 30 free spins on offer, as well as a Cash Crop Bonus where Coin symbols and their respective values can be collected.
The maximum prize that can be won on Rainbow Riches: Pick n Mix is 500x your wager. To achieve this, you must hit five identical special symbols on a single spin, which can be Road to Riches, Pots of Gold or Toadstool symbols. Instead of playing the corresponding bonus round for landing those symbols, you will trigger the instant cash prize.
The original title from the slot franchise, Double Bubble has always been regarded as one of the best online slot games in the UK. This game was launched in 2014, and like the Rainbow Riches franchise we mentioned previously, it was the catalyst for a host of spin-off games.
One of the main reasons for the popularity of the initial Double Bubble slot is the minimum bet size of 1p, so players of all types can enjoy it. There are 20 paylines in this slot machine, and the RTP is 96.02%.
The top payout that you can play for in this game is a massive 20,000x your wager, which will be awarded if you manage to land five Wild symbols on a single payline. You can also boost wins via the Bubble Line Win feature, which will multiply your combination by a maximum of 22x your stake if winning symbols are displayed within bubbles.
The main bonus round in Double Bubble is Pop The Bubbles, which is activated when a Bonus symbol appears on reels 1, 3 and 5 on a spin during the base game. When you are in this bonus round, you will choose from three bubbles on your screen, and you will be awarded a random multiplier if one is shown in the selected bubble.
You could pop some big slot prizes by playing Double Bubble Triple Jackpot, which went live on our site in 2019 as the franchise was continuing to grow, and the popularity of this game certainly helped that cause.
This online slot machine has a minimum bet size of only 1p, and the progressive jackpot can be won during the Bubble Popper Bonus, which has a seed value of £25,000. Although this game has the lowest possible bet size available, your chances of winning the progressive jackpot are proportional to your wager. If you play with a bigger stake, you will be more likely to win the prize.
The RTP in this slot is 95.53%, and there are chances to multiply your winning combinations by a maximum of 22x with the Bubble Line feature, which is applied when winning symbols are displayed in bubbles.
More big prizes are available for players in our popular slot Bouncy Bubbles, which is linked to the Double Bubble series. The minimum bet in this game is 10p, with 10 paylines available alongside an RTP of 95.38%, plus a jackpot contribution of 0.2%.
To complete winning combinations, you must have at least five identical symbols shown on a spin, and this cluster will explode once it has been evaluated and paid. This could lead to a chain reaction of wins being achieved from just a single spin! The empty spaces on the reels are filled by new symbols which fall down from above, and with every consecutive cascade that takes place you will increase the value of the multiplier that is applied to each win, up to a possible 5x.
Enter the Bubble Popper Bonus for your chance to land a progressive jackpot, with a seed value of £1,000. In this bonus round you will reveal prizes by selecting bubbles to pop, and as with Double Bubble Triple Jackpot, the higher your stake is, the more likely you are to win the pot.
Fishing-themed slots are among the most popular types around, none more so than Fishin’ Frenzy. This slot machine is essentially the flag-bearer for games of this ilk, and has sparked a series of games in the same way that Rainbow Riches has. You can play the original Fishin’ Frenzy slot from as little as 10p, and the game has an RTP of 96.12%, with 10 active paylines.
There aren’t as many bonus features as you may find in some of our new online slots, but it still remains one of our most played games. The Free Spins Bonus is unlocked when a minimum of three Bonus symbols are produced on a base game spin, and the Fisherman Scatter symbol becomes active in this feature, which will collect the values displayed on the Fish symbols when it appears.
Have a spin on our Pragmatic Play slot, Big Bass Splash. This game has proved popular among our players due to the classic feel of the slot machine, while also providing a range of different bonus features.
Big Bass Splash has an RTP of 94.60%, with 20 paylines on offer, and bets are available from only 10p per spin. Hitting at least three Fish Scatter symbols during the base game will unlock the Free Spins Bonus, where you could play with up to 20 free spins. There are five Free Spins Modifiers that can be triggered at random before you play the bonus, which could add extra free spins, extra symbols and more.
Given the popularity of Big Bass Splash, it’s easy to see why players also enjoy spinning the reels in Big Bass Bonanza. You can play this slot from 10p per spin, and it has 10 paylines available. The RTP of Big Bass Bonanza is 96.71%.
This slot machine follows the same theme as Big Bass Splash, with a Free Spins Bonus that can be activated by hitting at least three Scatter symbols across the reels on a base game spin. This bonus round can be re-triggered by accumulating Wild symbols on your free spins. For every fourth Wild that you collect, another 10 free spins are awarded, plus the value of the win multiplier will be boosted up to a possible 10x.
You can trigger instant cash prizes on your free spins as Wild symbols land. If one of these symbols appears on the same free spin as a Money symbol, the value on the latter will be collected and credited to your account.
Collect Wild symbols while playing your free spins and you will have the chance to move to the next level, which will reward you with additional spins, as well as increasing the value of the win multiplier up to a possible 10x.
As with some of the other slots that have inspired franchises that we’ve touched on in this post, Secrets of the Phoenix was so successful that you can now play a number of spin-off games on our site. This includes the likes of Secrets of the Phoenix Jackpot, and Secrets of the Phoenix Megaways.
In the original game, you will be able to spin the reels from as little as 25p, and 25 paylines are available. Cascading Reels are in play in this game, like we mentioned in Bouncy Bubbles, so you could string a sequence of winning combinations together from only one spin.
You can land Stacked Wilds in this game, which will appear if a whole reel is removed by a cascade. This will remain active for one cascade only, and new symbols will replace it after this point.
The main bonus in this game is Free Spins, and you can play this round when you have four or more winning cascades in a row during the base game. This bonus can be re-triggered too, so you can win even more free spins once you’re playing it.
