24 Hour Grand Prix: Overview

Red Tiger partner studio R7 puts the pedal down with the racing-inspired slot 24 Hour Grand Prix. Framed in a bygone era, it leans into vintage motoring with iconic cars, loud guitars, and plenty of swagger. As you chase the chequered flag, you’ll run into stacked symbols, two-reel wide Super Wilds, and a free spins round where the low-paying symbols are stripped from the reels.

Although the best-known endurance event is Le Mans, 24 Hour Grand Prix feels closer in spirit to the Monaco Grand Prix. The 6-reel, 30-payline layout sits in front of tight seaside bends that capture the essence of the principality’s Formula 1 circuit. Petrolheads will appreciate the selection of cars on display, including something resembling a Ford GT40, a Ferrari 330 P3, and a Porche 906 Carrera. Whatever the exact models, they’re all great-looking machines.

Sound is one of 24 the game’s big highlights. Revving engines ramp up the tension when Super Wilds stack across the reels, but the music steals the show. In the base game, a rock-meets-blues track plays that feels like an ultra-cool Rolling Stones vibe. You can almost imagine Keith Richards with a cigarette perched on his lip, face twisted into pure delight as those blue notes spill out from his fingers. The bonus round keeps the same attitude too, only it shifts up a few gears as the action swings through the corners.

To take your place on the grid, bets range from 10 p/c to $/€40 per spin, across any device. As an R7/Red Tiger release, the RTP is predictably a little under par at 95.73%. It’s not dramatically low, though, and it matches the “new” normal. Wins register on the visible paylines with a hit frequency of 3/5. The exact meaning of that score isn’t totally clear, but hits do land regularly and often come as multi-line payouts thanks to stacked symbols. A touch higher is the volatility, rated 4/5 on Red Tiger’s in-house scale.

24 Hour Grand Prix keeps things simple, with no sneaky mechanics to learn. Wins are made by landing three or more matching symbols across the 30 fixed paylines. The paytable contains nine regular symbols: 4 low-paying card suits and 5 higher-paying icons. The premium symbols are racing cars, paying from 3.8 to 11.4 times the stake for five of a kind. As noted, stacks can create full-screen hits worth up to 342x. Bigger rewards can come via the Super Wilds, which substitute for all paying symbols. Cover the reels with Super Wilds and the payout reaches 1,050 times the stake.

24 Hour Grand Prix: Features

You wouldn’t call 24 Hour Grand Prix packed with extras. Beyond Super Wilds, the only additional mechanic is a set of triggered free spins. You can’t hit Super Wilds outright. Instead, whenever 2 neighbouring reels are stacked with the same high-paying symbol, an animated 2×4 Super Wild forms in their place.

Land 3 or more Race Spin scatters on the reels and the Race Spins feature begins. Exactly 3 scatters grant 10 free spins, and each extra scatter in view adds 5 more spins. The key twist in Race Spins is that every low-paying symbol is removed from the reels.

24 Hour Grand Prix: Verdict

Even with middling stats and a fairly light feature set, 24 Hour Grand Prix ends up being more enjoyable than you might expect. A lot of that comes from the soundtrack and visuals together, which hint at a wilder time—drivers smoking fags and downing cans of Stellar between laps. R7 also made a smart call by focusing on retro motors instead of modern ones. There was room to do more, but the theme is still used effectively. With a bit of imagination, it’s easy to slip into a 1960s mindset—when cars were much less safe and victories came from grit, determination, a touch of skill, and a whole lot of luck.

Gameplay-wise, it’s more restrained than the setting suggests. Super wilds can help, but they frequently show up on the fourth and fifth reels, where they don’t always deliver much. Free spins can be similarly annoying too, even with the low pays removed. Honestly, it can start to feel repetitive—though non-racing fans might argue that repetition is exactly what you sign up for when watching cars circle a track for 24 hours. If everything lines up, the top potential reaches 2,166 times the stake.

Look beyond the underwhelming figures and you can still catch a glimpse of the relaxed golden-era racing vibe the studio was going for. It would have been even better if R7 had fully committed—pushing the theme harder, boosting the potential, adding more features, and perhaps polishing the presentation with extra animation. Still, what’s here is decent for what it is, as long as you can accept the below-average stats. If the numbers don’t bother you and you fancy a few spins to get your motor running, 24 Hour Grand Prix could be worth a quick go.
