Triple Diamond Free Slot Machine Review

Triple Diamond is a free online slot game released in 2015 by IGT. It has only 3 reels and counts wins across 9 paylines – opting for a 1950s Vegas slot design complete with BAR and Lucky 7 symbols. Classic jingle plays with every spin, animations are just symbols blinking, every design choice is paying homage to nostalgic fruit machines you’d find in pubs and casinos decades ago. Triple Diamond has been fairly popular with casino goers and online gamblers for a good few years after release. According to Slot Catalog it hit top 247 most played slot in the UK in July 2018, but steadily dropped off in player base since then.

Play Triple Diamond Slot by IGT

This game is a sequel to IGT’s Double Diamond that came out in 2005. It had only 1 payline and was inspired by one-armed bandits of old. Triple Diamond introduced slightly more complexity by offering 9 Paylines with potential for increased wins for Wild multipliers. They’re basically different variance versions of the same game, following a single theme. That’s why the slot intentionally plays like something from 50 years ago. There’s no Feature, no Free Spins, no progressive Jackpots and zero Bonus Games. Only the Triple Diamond symbol that acts as Wild and substitutes wins to multiply payouts. As any modern IGT slot, it’s built using HTML 5 and Javascript, which means the game instantly adapts for any screen width. You can play Triple Diamond slot on:

  • Android mobile & tablets.
  • Desktop PCs and laptops.
  • iOS iPhone and iPad.

Available as part of a mobile app or simply ran in any modern browser like Firefox, Chrome, Edge, Safari, Vivaldi, Opera, etc.

Bonus Rounds & Other Bonuses

To address the elephant in the room – there are no Bonuses in Triple Diamond slot. It doesn’t have a Feature and there’s nothing in the mechanics to break classic reel spinning. It only has one Special Symbol that works as Wild – there’s no special event associated with hitting it. They only work as win multipliers of x3 and x9 for symbol substitutions.

Free Spins Bonus & Jackpot

Similarly, there’s no in-game Free Spins Bonus. Triple Diamond stays true to one-armed bandits of old and doesn’t provide any Bonus Spins or re-spins. The only possible way to get them are Welcome bonuses – some top online casinos offer new players up to 200 Free Spins on registration. Websites such as LeoVegas even offer no deposit bonuses for new accounts.

Triple Diamond has a Jackpot equivalent for striking 3 Wild symbols – it pays 1199x current stake. What’s interesting about the game are the limits, bets per line start at a minimum 25 and go all the way to 500, so 4500 coins per spin. Stakes as high as $600 per spin made the game popular with high rollers looking for big jackpot strikes. This slot isn’t hooked to a Progressive Jackpot – although IGT-specific promotions and carry-over bonuses may apply at certain casinos.

How to Play Triple Diamond Slot

There’s not much learning to play Triple Diamond online, it only has the following controls:

  • Set line bets and turn lines on/off with the +/- buttons on bottom left.
  • Enable «Autoplay» up to 50 spins at given bet on bottom right.
  • Call on the Paytable and Game Rules as well as turn off sounds at top right.
  • Spin the reels with the big yellow «Play» button in the middle.

Because the game is coded in HTML 5 / Javascript, there’s also no need to enable Flash player or add permissions on the websites. It just loads with instant play, using the assets already available in browser when possible.

How to Win Big

Triple Diamond is built around this single Wild symbol that the slot is named after. All big payouts come from hitting the Triple Diamond symbol in any capacity. When it substitutes other symbols, multipliers apply:

  • 3x for a single substitution.
  • 9x for a double substitution.
  • All 3 hit jackpot at 1199x stake.

Every time a solid combination with Triple Diamond lands, a big win follows. There’s no other path to big wins in this slot, as it’s built to emulate classic high-limit machines with very few features.

Paytable & Bonus Symbols

Compared to most slots on the market, Triple Diamond has a rather simple paytable. There are only 5 basic symbols, each pay only in matches of 3:

  • Lucky 7. Pays 100x.
  • Yellow BAR. Pays 40x.
  • Purple BAR. Pays 20x.
  • Blue BAR. Pays 10x.
  • Any BAR. Pays 5x.

Non-matching BAR wins count as Any BAR wins. Since this is a 3-reel slot, it’s filled with BLANK symbols that’ll come up fairly regularly. There is only 1 Bonus Symbol:

  • Wild Triple Diamond. Substitutes any other symbol and multiplies wins by x3 or x9 depending on combination. Coming up with a blank, one will offer a 2x win and two – 10x. Hitting all 3 of them strikes the x1199 jackpot.

Simplicity and potential for high stakes made this machine successful with Vegas punters.

Chances to Win

Triple Diamond slot has a Return-to-Player (RTP) of 95,06%. This means that long-term for every $100 gambled, $4,94 goes to the house. Odds-wise, it’s used as an indicator of win chance, showing which way the slot is skewed. 95% is about industry average among Vegas slots, with some of the most generous machines on the market going as high as 98,9%. When it comes to Triple Diamond big wins, RTP is a good indication, but the high stakes change the math. As high rollers learned, big bets change average slot experience on many machines. Overall, Triple Diamond offers below average chances to win far above average rewards. It’s highly volatile, unpredictable, but has potential higher than most slots on the market.

Play for Real Money

To play Triple Diamond for real money, you have to first find an online casino that has it on the slot list. As an older game, it’ll mostly be available at branded IGT casinos or top websites that offer rosters in hundreds of games. Then the process is:

  1. Register and provide a valid proof of identity to confirm age and region.
  2. Choose payment method – credit card, bank wire, or one of many payment processing systems available (Skrill, AstroCard, PaySafeCard, etc.)
  3. Claim Casino bonuses. In LeoVegas, Betat, and others new accounts get up to 200 Free Spins. Certain websites like Jackpot City offer deposit matches up to $1600.
  4. Confirm ability to withdraw funds with chosen method. Remember that bank wires can take up to 5 days, see which alternatives are available at casino.

Once this is over, you can spin the reels on all he best Vegas slots. Triple Diamond has exactly the same gameplay in Free Play for fun as it does in real money mode.

NOTE: Scope your bets! Because this high-limit slot allows huge stakes upwards of $600 per spin, it’s important to check what you’re getting into before hitting the «Play» button.

No Download No Registration

Free version of Triple Diamond is available on FreeSlotsHub with instant play. As most IGT slots, it’s integrated into websites using HTML 5 – using code already available in your browser. The slot needs no download and no registration, it just loads and runs. Because of this design, IGT online slots also require little to no bandwidth. Only downside they’re always online. There’s no way to spin the reels without internet connection due to the game needing to call on its server before every player action.

Tips & Strategies

When you play Triple Diamond, there’s no strategy to speak of. For starters, it’s a high variance 3-reel slot without any mechanical complexity. It’s deliberately designed to offer no player choice. Your actions don’t matter at all aside from how many credits you’re willing to wager with a spin, which is purely subjective. Some modern slots warrant tips about how to make decisions in bonus features, game mechanics, gambling, and so on – none of these apply to Triple Diamond. High value, unpredictable spins are its appeal and reason why the game is popular with punters. As a responsibility note, we recommend trying the game in Free Play and taking advantage of Casino Bonuses described earlier before betting any real money.


Triple Diamond doesn’t have a dedicated Mobile application. However, any online casino that has it on their list will have an app where players can access it and many other slots. Applications such as Casino Joy and Big Win even allow to play slots offline, they’re available for Android at Google Play and App Store for iOS devices.

Triple Diamond is hard to fault for simplicity – it’s designed that way and wears the inspirations on its sleeve. Slot like this is almost refreshing when games coming out in 2019-2020 are all flashy, chockfull of bonuses, and distract the player with numerous gimmicks. In contrast, Triple Diamond needs zero learning and takes no effort to get into. That level of accessibility made it popular, and as a return to classic slot machine roots it does exactly what it set out to do. It’s built to cater for specific gamblers – those who play high-limit and share a nostalgia for classic Vegas slots.

How is Triple Diamond different from Double Diamond by the same developer?

Double Diamond was the original that came out in 2005. It has only 1 payline in the middle. Triple Diamond can be seen as a supercharged version of that with higher stakes, 9 paylines, and potential for jackpots up to 1199x compared to 1000x in the original. Double Diamond also had the Cherry symbol that the newer game did away with.

Are there other games in this series?

Following the success of Double and Triple Diamond, IGT also released different variations on these slots. There’s a Triple Double Diamond combination slot that uses Wilds from both games and hooks to a progressive jackpot. Additionally, there are Hot Roulette versions of the slot that take advantage of the new IGT bonus game.

How do payouts compare to other free slots online?

95,06% RTP is fairly average, and the game doesn’t have a six-digit progressive Jackpot to chase. Its strong suit is high value spins for hundreds of dollars, but there are all around better slot games in terms of raw payouts.

What are the differences between land casino and online version?

None whatsoever, it’s exactly the same slot – IGT developers emphasize the authentic experience in the rules description.
