Triple Diamond is IGT’s follow-up to Double Diamond, and the online version is a 3×3 reel game with 9 paylines released in 2015. The reels hold bars, red sevens and the Triple Diamond logo, which is wild, triples any win it is part of, multiplies a win by nine when two land and pays 1,199x the line bet for three. There are no free spins, and it returns 95.06%. The free demo below is a similar diamond slot.
Triple Diamond online runs on three reels and three rows with 9 paylines: the three horizontal rows plus diagonal and V-shaped lines, all paying left to right. Players can choose from 1 to 9 lines, and each line carries its own bet. Stakes depend on the casino, and most listings run from about 10 cents to between $100 and $180 a spin. Most sources give the return as 95.06%; one review site lists 96.50%, a figure no source explains. Volatility ratings conflict, from low through medium to high, so no rating is given here, and no hit frequency has been published. The top award is 1,199x the line bet for three Triple Diamonds on a line; with all nine lines in play, a screen full of Triple Diamonds would pay 1,199x the total bet. There is no progressive jackpot.
Triple Diamond Pokies Characteristics
Each active line is a separate bet, and a line pays for three of the same symbol, any three bars in a mix, or at least one Triple Diamond. The wild substitutes for any symbol on the payline and applies its multiplier at the same time. There are no cherries on these reels, unlike in Triple Double Diamond, so a line without three matching symbols or three mixed bars pays nothing unless a Triple Diamond is on it.
That is the whole game. There are no free spins, scatters, bonus rounds, gamble or bonus buy, and the top award is fixed rather than progressive. Some listings tick boxes for free spins, scatters or bonus rounds; those are template errors, and the paytable has no symbol that could trigger any of them. Autoplay is available, up to 50 spins at one site, along with a fast-play option.
Pays below are multiples of the line bet; the wild’s x3 and x9 multipliers apply on top when it completes a win with other symbols.
There are no scatter pays. The two lowest Triple Diamond lines are the blank-line pays: one Triple Diamond on a line with nothing else matched pays 2x, and two with a blank pay 10x. Some review sites present these as a contradiction of the x3 and x9 rule, but they cover a different case. With all nine lines active, a single top line is worth about 133x the total bet; it reaches 1,199x the total bet only when every line carries three Triple Diamonds, which takes a full screen of them.
The Triple Diamond logo is the only feature. It substitutes for any symbol on the payline, and the win it completes is multiplied: one Triple Diamond triples the pay, two multiply it by nine, and three pay the 1,199x top award instead. So two red sevens and a Triple Diamond pay 300x the line bet rather than 100x, and one seven with two Triple Diamonds pays 900x.
This is a step up from Double Diamond, where the wild doubles or quadruples. The trade-off is in the lines: Double Diamond plays one line for the whole stake, while Triple Diamond spreads the stake across up to nine, so the same total bet buys smaller line bets and each multiplied win is worth less in dollars. Without a diamond on a line, the best ordinary result is three sevens at 100x.
At 95.06% Triple Diamond keeps about 5 cents of every dollar bet over the long run, slightly more than Double Diamond keeps at 95.44% online. Volatility is not published and ratings conflict, but the paytable shows the shape: the bottom of the table pays 2x to 10x the line bet, the sevens and multiplied wins are where a session recovers, and the 1,199x line needs three wilds on the same line.
At 10 cents a line on all nine lines, a spin costs 90 cents and $45 covers 50 spins; the long-run cost of that turnover is about $2.22. Three sevens on one line at that stake pay $10, a seven with two Triple Diamonds pays $90, and the top award is $119.90. Playing a single line at 90 cents puts the whole stake behind each win, so three sevens would pay $90, but far fewer spins pay anything.
The online game is a port of IGT’s land-based Triple Diamond, a three-reel mechanical stepper on the S2000 cabinet. No source dates its release; one database says Double Diamond, from 1989, came out a few years earlier. One dealer listing for a quarter, three-coin machine gives its top award as 4,000 credits, and the online 9-line maths does not apply to it. Double Diamond, which we also review, is the one-line original with a x2 and x4 wild, a 1,000x top award and a 95.44% online return.
The family has grown around them. Triple Triple Diamond is a single-line S2000 stepper with a progressive bar. Triple Double Diamond with Hot Roll has 3 reels and 20 lines, combines Double Diamond and Triple Diamond wilds into multipliers of x4, x6 and x9, and adds a Hot Roll dice bonus; one estimate puts its return at about 91.1%. Wheel of Fortune Triple Diamond, according to one database, has 5 fixed lines, a wheel bonus from three Spin symbols on a line and two progressives at qualifying bets; our Wheel of Fortune review covers the wider franchise. Hot Roulette Triple Double Diamond adds a symbol that switches to a roulette wheel.
Triple Diamond is a Las Vegas reel slot recreated on a screen: the Triple Diamond logo, red sevens and single, double and triple bars on white-backed reels against a black and violet background. One review describes green, purple and orange bars and another names different colours, so the paytable labels are a safer guide than colour. The sound is retro beeps and buzzes in the style of a traditional fruit machine, and one reviewer found it grating after a few minutes. The game is built in HTML5, runs on desktop and mobile, and one site lists English, German, Spanish and French.
We found no evidence of Triple Diamond in Australian clubs, pubs or casinos. IGT (Australia) is an approved supplier in the ACT, but its game list in a 2016 ACT instrument has no Diamond titles, the other ACT instruments checked had none either, and our Double Diamond research found no IGT Diamond game in eight more. Online, we found no IGT statement on offering its games to Australian players or on restricting them, and Australian law does not allow online pokies to be offered to people in Australia, so availability varies and a lobby search for the title is the way to check. We found no official free demo from IGT; the free Triple Diamond slots we found are on review sites. Since July 2025 IGT’s slot business has been owned by Apollo-managed funds, merged with Everi, and still trades as IGT.
Triple Diamond suits players who want a classic reel slot with a little more going on than Double Diamond: nine lines, a wild that triples or multiplies by nine, and a paytable that takes a minute to learn. It does not suit anyone who wants free spins, bonus rounds or a jackpot that grows, and at 95.06% it is on the expensive side. The one thing to check is which Diamond game has loaded, because Double Diamond and Triple Double Diamond have different lines, multipliers and returns, and the online 9-line maths does not apply to the classic machine.
Most sources give 95.06% for the online 9-line game. One review site lists 96.50%, and no return was found for the classic land-based machine.
It substitutes for any symbol on the line. One in a win triples the pay, two multiply it by nine, and three pay 1,199x the line bet.
1,199x the line bet for three Triple Diamonds on a line. With all nine lines active that is about 133x the total bet, and a full screen of Triple Diamonds pays 1,199x the total bet.
Choose 1 to 9 lines and the bet per line, then spin. A line pays for three matching symbols, any three bars or at least one Triple Diamond, and there are no bonus rounds to trigger.
No Australian venue approval was found for any Triple Diamond, and we found no IGT statement on Australian online play. Availability varies, so a lobby search for the title is the way to check.
