Triple Double Diamond RTP and Wagering

Triple Double Diamond - RTP and Wagering

Triple Double Diamond features a classic 3x3 reel setup with 9 fixed paylines. The aim is to line up three matching symbols to win one of the prizes shown on the paytable above the reels. You can bet between £0.09 and £4.50 on any spin.

This slot game is highly volatile: it may not pay out as often as slots with lower volatility, but the prizes can reach decent amounts. The biggest payout up for grabs is 5,000x your bet, which you’ll only win if you land 3 Triple Diamond symbols on line 9.

Unfortunately, Triple Double Diamond has a low theoretical RTP of 92.01%. When the average RTP for slots is 96%, this game’s RTP is much lower than you might expect it to be. Progressive slots usually have such low RTPs, but there are no major jackpots available here.

Best Casinos to Play Triple Double Diamond

The Triple Double Diamond slot is available for you to play now at multiple online casinos in the UK. Here are the best slot sites to visit:

Triple Double Diamond Symbols and Audio & Video Design

Triple Double Diamond has a retro design and recreates the experience of playing a traditional slot machine right on your device. The big, chunky reels take up around half of the screen, with subtle lighting effects adding extra realism. 

The rest of the space is dedicated to the paytable. Having the paytable on display while you play helps you keep track of how much each combination is worth without needing to open a separate page. 

The sound design is excellent too. Each time you spin the reels, a retro electronic effect triggers. But you’ll also hear the low-key ambient sound of a bustling casino floor in the background.

As it’s based on classic slot machines, Triple Double Diamond’s symbols should be familiar to most players. Cherries and single BAR symbols award the smallest prizes. Double BAR, triple BAR, blue sevens, and red sevens pay higher prizes.

But the top-paying symbols are the Double Diamond and Triple Diamond symbols. Match 3 Triple Diamond symbols on lines 1 - 8 to win 1,000x your bet. But land 3 on line 9 to scoop the max win of 5,000x your bet instead.

Triple Double Diamond Mobile Features

IGT has developed Triple Double Diamond for desktop and mobile, so you can play it on most devices. The game is convenient and easy to use on mobile screens, with a simple layout that makes great use of the space. In my experience, it plays best in portrait mode, but it’s still user-friendly in landscape.

Triple Double Diamond Bonus Features

Like many other classic-themed slots, Triple Double Diamond’s main focus is the core gameplay. As such, it has just one bonus feature: a pair of multiplier Wilds. But while this is a straightforward part of the game, it can increase the size of your wins on any spin.

Triple Double Diamond Feature

Wild Symbols

The Double Diamond and Triple Diamond logo symbols are Wild. Both Wilds substitute for all symbols except for each other.

Each Double Diamond Wild that contributes to a winning combination multiplies the payout by 2x. But Triple Diamond Wilds multiply any wins they create by 3x instead. More than one Wild may contribute to a win and award multipliers of up to 9x.

Triple Double Diamond Final Thoughts

Triple Double Diamond is a simple but very playable take on the classic slot theme. The presentation may not be to everyone’s taste, as the paytable takes up half of the screen, but it accurately recreates the look of a real slot machine.

If the multiplier Wilds substitute for other symbols in winning combinations, they can double or triple your payouts. But this is the only feature in the game, which may make Triple Double Diamond less appealing if you prefer multiple bonuses.

Still, you might feel that this is the right choice for you if you tend to play traditional slots. The max possible win is decent at 5,000x your bet, though the high volatility can make payouts scattered. And the theoretical RTP is very low at 92.01%, so keep that in mind if you decide to give this a try.
