Game rules

IGT is the powerhouse behind some of the top slots games UK fans simply can’t get enough of, including Da Vinci Diamonds and Siberian Storm. But their roots have always been firmly based in the world of land-based gaming, so they know better than most just what slots fans are looking for from their gaming session.

Triple Diamond symbols

There are only five symbols to watch out for on the reels of Triple Diamond, and three of those are BAR icons. But you’ll also encounter the traditional Lucky Red 7, which pays out 100x your stake for matching three across an active payline. The best returns come from the Triple Diamond logo, which is also the game’s Wild substitution symbol. It pays out like a Scatter too, in addition to adding multipliers to substitution wins, so it’s the symbol you’ll be paying the closest attention to during your spinning session.

Min/Max wagers & lines

The nine paylines in Triple Diamond are variable, so you can choose to play with just one, all nine, or any number in between. We advise activating all of them if you can, as there are few things quite so dispiriting as seeing a big prize-winning combo spinning up – only to discover the payline it’s on isn’t active!

Paylines cost from 25p each, so with all nine in play, a spin will cost from £2.25 up to an eye-watering £900. That’s serious high-roller territory, which is why it’s well worth taking the time to play some Triple Diamond free slots games to start with.

Pay table & bonus rounds

Match three symbols across an active payline to win cash prizes, paid as multiples of your stake.

• Any combination of BAR symbols  =  5x
• Single BAR  =  10x
• Double BAR  =  20x
• Triple BAR  =  40x
• Lucky Red 7  =  100x
• Triple Diamond  =  2x,  10x,  1199x

The Triple Diamond game logo is the Wild Symbol, so can stand in for any other icons, helping you to land one or more winning combos. Better still, it brings a 3x Multiplier to winning substitutions, increasing to a 9x Multiplier when two Wilds contribute to a win.

But the Triple Diamond logo also delivers cash prizes according to a Scatter Pays mechanic, so just one on the reels awards 2x your stake, increasing to 10x your stake for two Triple Diamond symbols. Land three symbols to win the top payout, worth an impressive 1,199x the cost of your spin.

Animation, graphics, and soundtrack of Triple Diamond

The design of Triple Diamonds leaves you in no doubt that this is a classic slots game. Big, chunky symbols spin up on darkened reels, giving the effect of playing at a land-based slot machine. There are generic game sounds as the reels spin, with some realistic clicking noises that mimic the sound of mechanical reels falling into place. This isn’t a game for action and adventure slots fans, but gamers in search of solid, classic reel-spinning action, with the possibility of some big potential wins, will find a lot to enjoy.

Triple Diamond RTP and volatility

IGT aren’t renowned for their return to player ratios, but the Triple Diamond slot RTP comes in at a pleasing 96.5%. That’s half a percentage point higher than the industry average for an online slots game, although despite what you might have heard elsewhere it doesn’t give any real indication of your potential winnings. Because whether it’s the Triple Diamond RTP, or the White Rabbit slot RTP, all this statistic tells you with any certainty is the house edge. So you can be sure that the casino takes 3.5% of everything that players wager on this particular game.

Volatility gives a much better idea of how well you might get on with a game. In the case of Triple Diamond, the volatility is medium to high, which is why we recommend exploring some Triple Diamond free slots before wagering real cash. There are some big cash prizes on offer, but they won’t spin up for everyone, and modest bankrolls could come unstuck pretty quickly. Trying some Triple Diamond demo gives you a good idea of what might lie ahead, but without putting your own funds at risk.

Triple Diamond verdict

Double Diamond was the original IGT slots machine game that began pulling in the players, so the developer has been quick to create an updated version of the game, with even more winning potential. Triple Diamond may offer stripped back gameplay with a lack of bonus features, but this is part of what helps to make this game such a firm favourite with fans.

With no bonuses or side games to bother with, Triple Diamond gives you classic three-reel slots action with the chance to spin up some big cash prizes. Just watch out for that volatility, and be sure to explore some Triple Diamond demo spins before risking your own bankroll on your spinning session.
