24 Hour Grand Prix Slot Review

24 Hour Grand Prix: Overview

24 Hour Grand Prix drops me straight into a retro racing weekend, all twisting harbour corners, dream machines and a swaggering rock soundtrack. The 6 reel, 4 row, 30 payline layout looks simple on paper, yet stacked symbols and wide Super Wilds keep the base game ticking over. It feels like a laid back love letter to sixties endurance races, where style matters nearly as much as crossing the line first.

Betting starts at 10p a spin and, on the versions I have played, usually tops out at forty quid, though some set ups go higher. Red Tiger’s maths keeps things pretty punchy, with mid to high volatility and a hit rate around the twenty percent mark. Different configurations list return to player figures from 94.70% up to 95.73%, while the stated maximum win sits at about 2,166 times your stake.

24 Hour Grand Prix - Design and Symbols

The design work on 24 Hour Grand Prix hits that Ford v Ferrari era right between the eyes. When I load the slot I land trackside, city lights and sea framing the circuit, while a snarling bluesy rock track chews away in the background. Spins are punctuated by engines howling past, Super Wilds roar into life with tyre noise, and the whole package carries a relaxed yet gritty racing atmosphere.

On the reels, nine regular symbols carry most of the work. Four card suits with chrome patterns sit at the lower end, paying modestly and often falling in stacks. The premium set is where the slot really shines, with five gorgeously drawn retro race cars, headed by a Ford GT40, then Ferrari 330 P3, Porsche 906 Carrera, Ferrari 275 and Alpine A210, all capable of landing stacked to cover entire reels.

24 Hour Grand Prix - Technical Info

Under the bonnet, 24 Hour Grand Prix runs on a 6 by 4 grid with 30 fixed paylines and a fairly wide betting spread. Some versions cap wagers at forty units, others reach two hundred, so I always check the paytable first. The game leans towards high volatility, pairing a modest hit frequency with a relatively low RTP setting and a maximum theoretical payout of around 2,166.3 times the bet, before any progressive jackpots.

24 Hour Grand Prix - Bonus Features

Feature wise, 24 Hour Grand Prix is not overloaded, yet the few extras it carries fit the theme nicely. All symbols land in stacks, so it is common to see multiple lines pay together. When two adjacent reels fill with the same high paying car, those stacks merge into a 2 by 4 Super Wild, covering both reels and substituting for regular symbols. Hit a screen full of these and the quoted payout is over a thousand times stake.

The main bonus round is Race Spins. Three scatters with the logo in view award ten free games, with every extra scatter adding five more spins to the tally. During this feature all low paying card suits are stripped from the reels, so only cars and special symbols remain. On a good run, stacked premiums and Super Wilds combine here to throw out some very tidy hits, far beyond what I usually see in the base game.

Some versions of 24 Hour Grand Prix also plug into three progressive jackpots, triggered by landing a trio of jackpot scatters and spinning a separate prize wheel for Hourly, Daily or Big Drop pots. After any win, there can also be a Gamble wheel, split into red and green segments, where you risk your payout for a shot at a bigger one. The stated figure for that side game sits around ninety four percent RTP.

The 200 Spins Experience in 24 Hour Grand Prix

I gave 24 Hour Grand Prix a proper shakedown with a 200 spin test, staking 60p a go. The first half of the session felt brutal, with long stretches of dead spins and only the odd small line win breaking the run. Just as I was thinking about bailing, a stacked car set morphed into a Super Wild block for a Mega Win worth 171 times my bet, dragging the balance back into profit.

Across the whole sample I never actually triggered Race Spins, which says a lot about how unforgiving the maths can be. A couple of thirty times stake hits kept the session alive between droughts, yet the pattern was very streaky. For me, this is a slot where you either land something chunky fairly early or you watch the bankroll erode, so I keep stakes controlled and treat it as a high risk punt.

24 Hour Grand Prix - Verdict

All told, 24 Hour Grand Prix gives me a cracking atmosphere, stylish retro motors and a soundtrack that burrows into my head, but the numbers are on the harsh side. Lowish RTP, high volatility and limited features make this more of a purist’s racer than a casual crowd pleaser. When the stacks line up it can throw out thrilling wins, yet for longer sessions I treat it with caution and stick to short, cheeky bursts.
