Game Rules

Double Diamond started out as a land-based slot, quickly gaining a huge following of fans who appreciated its pared-back ethos and superb winning capabilities. And now IGT has brought it to a new generation of online players, who can explore its potential for themselves, without even having to leave home to try it out. Plus there's even an update to this game as can be seen in our Triple Diamond review!

Double Diamond symbols

There aren’t many symbols on the reels of Double Diamond, with no poker cards or playing card suits to worry about. Single, double and triple BAR icons all appear, as do cherries and lucky red 7s. But it’s the Double Diamond game logo that you’ll be hoping to spin up on the reels as often as possible. Not only is this the Wild icon in the game, but it’s also the highest-paying symbol on the paytable in its own right – and it brings Multipliers to any wins it substitutes in too!

Min/Max wagers & lines

There’s only one fixed payline in this game, so it’s simple to play and understand. Individual casino operators can set their own minimum and maximum wagers, so depending on where you play, you can expect options from 10p up to £500 per spin. That’s a huge range with something for everyone, although not all players can expect to end up in profit from the game. We strongly recommend playing as many Double Diamond demo games as possible before playing with real money, to see whether it suits your attitude towards risk.

Pay Table & Bonus Rounds

Some games come with loads of different symbols, as well as bonus icons that trigger all sorts of side games and free spins. But there’s no Double Diamond free spins or bonus rounds, and there’s only one bonus symbol to consider as you spin the reels.

Cherries are the only icons that payout for landing one, two or three symbols across the payline, returning 2x, 5x, and 10x your stake respectively. And landing any combination of BAR symbols will result in a payout worth 5x your stake. All other game symbols payout for landing three across the central payline as follows:

  • Single BAR  =  10x
  • Double BAR  =  25x
  • Triple BAR  =  40x
  • Lucky red 7  =  80x
  • Double Diamond Wild  =  1,000x

Double Diamond Wilds can stand in for any other symbols on the paytable, and when they contribute towards a win they’ll add in a multiplier, for even bigger cash payouts. One Wild in a winning combination awards a 2x multiplier, rising to a 4x multiplier when two Wilds contribute to the win.

Animation, Graphics, and Soundtrack of Double Diamond

If you’re on the lookout for cutting edge graphics, slick animations and an atmospheric soundtrack then Double Diamond is highly unlikely to be the game for you. This is no-frills gaming, so expect basic graphics and generic game sounds, exactly like the Enchanted Prince slot, which is very similar in that respect. But given the retro vibe to this game, it’s clear that players will only be interested in spinning up the big cash payouts, so this is probably a game aimed at classic purists and high rollers, rather than the more casual player.

Double Diamond RTP and Volatility

The Double Diamond slot RTP comes in at 95.44%, which is a little below the average for an online slot, but still perfectly respectable. Some people will tell you that the RTP shows the amount you’ll win from staking £100, but that’s not the case, as game outcomes are completely random – some players will experience massive wins, while others won’t win back any of their stakes.

For this reason, we always tell our site visitors that RTP is only part of the story. Whether it’s the Double Diamond RTP or the Fat Santa slot RTP, it’s essential to consider the statistic in conjunction with a game’s volatility. In the case of Double Diamond, this is high, making this a risky game for low-stakes fans.

Limit the risk by trying out as many Double Diamond demo spins as you can, before thinking about wagering real cash. Double Diamond free play games give you valuable insights into gameplay, indicating how well your own funds might perform if you decide to wager them on the reels.

Mobile Availability

IGT created Double Diamond as a land-based slot machine, and although it’s made the leap to online casinos, the technology is still a little dated if compared to recent slot hits like the one found in our Reactoonz review. It’s possible to access this game on mobile devices, but it doesn’t play particularly smoothly, so serious players will find the best results from playing on your laptop or PC.

Double Diamond Verdict

Fans of no-frills gameplay with the chance of some big payouts will find themselves drawn to Double Diamond. Like old-school classics such as the one found in our Cleopatra review, this is a game that’s been enthralling players for years at land-based casinos, and now a new generation of players can enjoy online gameplay too.

But if you’re not a high-risk gamer, or if you have a modest gaming budget, we strongly recommend you explore Double Diamond free play games before moving onto real-money play. The volatility can be exceptionally cruel to modest bankrolls, so avoid risk by testing your luck first!
