IGT is one of the most popular slot developers, creating some of the best slot machines used at traditional casinos. The developer has also made its fair share of online slots, including Triple Red Hot 777. This is a classic slot with a 3x3 reel layout, though it includes somebonus features like free spins and spitfire multipliers.

When you load up Triple Red Hot 777 on your device, the reels will pop up in the centre of the screen, with the control panel directly below. On these controls, you'll find the line and line-bet options. Change these using the plus and minus buttons depending on how much you want to risk on each spin. Your total bet is shown next to them.
In the centre of the control panel is the spin button, which you tap to activate the reels for a single spin. The game displays your most recent win and currently available credits on the right side of this. In the far right corner, there's the autoplay option, which allows you to set up to 100 spins or activate profit and loss limits.
Above the reels, there's a sound option which toggles the game's music and sound effects alongside the game rules and paytable.
Opening the paytable reveals the various symbols and their values. This slot keeps it simple, with just seven symbols in total. There are five regular symbols and two bonus symbols, which, if you're lucky, can trigger the game's special features.
At the bottom of the paytable are the plain white 7s, which pay 20 coins for three on a line. The blue 7s pay 25 coins for three of a kind, while a single red hot seven pays 40 coins. The double red hot 7s pay 80 coins for three of a kind, and triple red hot 7s pay 150 coins. Any three of these symbols combined on a line will pay five coins.
The game's wild is the Triple Red Hot 3x symbol, which will substitute for any other regular paying symbol. However, it also pays out two coins for one on a line, ten for two on a line, and 2,000 if you land three of a kind.
The best classic slots are straightforward, and Triple Red Hot 777 is no different. There are just five paylines in this game; to win, you must land symbols along them. Matching combinations of high-value symbols give you the most significant wins, but you can combine any three symbols for a win.
The wild is the Triple Red Hot 3x symbol, and it will substitute for any regular paying symbols to help form winning lines. Also, whenever it substitutes to create a win, the payout is tripled. More than one multiplier can combine to make up to 9x.
The bonus symbol is a scatter, and landing three in any position will pay 1x your bet and unlock seven free spins. It's possible to retrigger this bonus up to a maximum of 700 free spins. The third and final unique feature comes into play during this bonus round.
Each spin during the bonus round triggers a random spitfire multiplier between 2x and 7x. These multipliers will affect all wins except for the Triple 777 3x three-of-a-kind win.
The game's maximum win is 20,000x your bet, which would mean an impressive $3,000,000 win if you were playing at the highest possible bet.
Triple Red Hot 777 has an RTP rating of 94.91%, lower than average for online slots. The volatility rating is high, so you'll typically encounter fewer wins, but payout sizes are more prominent on average than other slots. This was my experience when I played, too. I experienced a relatively low number of winning spins but ended up in profit after some big wild wins were multiplied.
It's important to remember that RTP and volatility ratings are calculated over thousands of spins. While they give you an idea of what to expect from the gameplay, your returns can vary greatly depending on your luck. Random number generators determine each spin outcome, and shorter playing sessions can experience more significant variability.
Classic slots focus more on gameplay and winning potential than style and visuals, opting for simple imagery and basic graphics. However, that doesn't mean they have to look bad. IGT has found a comfortable middle ground between classic style and modern design, with classic symbols that look great. The designs aren't elaborate or complex but stand out on the reels.
The animations for each spin make the game look exactly like an old-school slot machine, and the static background helps to add to the theme, too. While essential, it still looks perfect and allows the game to run smoothly on all devices. The sounds and music remind me of slot machines, with IGT putting a lot of effort into making this game look and feel exactly like a classic slot should.
The real money version of Triple Red Hot 777 lets you risk money on every spin to win real cash payouts. However, you can also play the game risk-free if you prefer. The Triple Red Hot 777 demo is available on this page, letting you spin the reels as much as you like without spending anything.
You can use the demo to test the features such as the wilds, free spins and spitfire multipliers, all for free. Once you've gotten to grips with the game and how it works, you can load it up at your favourite online casino and play for real money. I always recommend giving the demo a go, as it's a great way to determine whether you're interested in the game and its features.
Classic slots are among my favourite online slots, offering a slice of nostalgia and the potential to win massive payouts. Although bonus features weren't that common in the original slot machines, technological advances soon meant that games could offer wilds, free spins and multipliers.
Of course, modern online slots are often packed full of bonus features, and many classic slots also use them. If you're looking for more classic slot action with many fun bonus features, you can check out games like 7s Wild, Seven 7s and 777 Super Strike.
If you're a big fan of classic slots and straightforward gameplay, there's much to love about Triple Red Hot 777. Although the simple reels and features might put some players off, they still created a fun experience when I sped the game.
The wild multipliers are always active, and if you're lucky enough to trigger the free spins, the spitfire multipliers can trigger some big wins. The graphics are essential, but the game still looks great, with lots of colour and lively animations. Check it out or try some of our other recommended classic slots for more action.
