24 Hour Grand Prix is a game from slot provider Red Tiger Gaming, released in 2020, and built firmly around the glamour of Monte Carlo racing. The reels are set against a trackside background, featuring retro sports cars as premium symbols and a lower-value mix of card suits. The game’s tone is quite dark, helping to give it depth, but it can feel heavy over more extended play than may be advisable.
As we tested the game, we noticed what I will share below.
The 24 Hour Grand Prix slot is backed up by robust and simple mechanics. While some titles are filled with plush gimmicks, featuring multi-layered principles, 24 Hour Grand Prix chooses to strip and bake lean mechanics and instead stack the action around Super Wilds, free spins and jackpots.
Symbols are split across three groups:
During my test, the payout structure leaned heavily on stacked cars and Super Wilds. This makes base game wins spikier than in many slots, but it keeps the potential lively. It feels more balanced than Drive Multiplier Mayhem, which relies almost solely on its bonus round.

24 Hour Grand Prix paytable
Let’s cover the basics, including how to play, reel and row layout, paylines, betting choices, autoplay, and RTP.
The 24 Hour Grand Prix slot game features a 6×4 layout with 30 fixed paylines; therefore, changing the number of lines is impossible. Bet sizes are £0.10 up to £40 per spin, which keeps the options open for the reserved player and those who want to bet more. To play, you click the spin button or press the spacebar. The stake can be adjusted by using the + and – buttons. The pay table and other information are in the main menu; below is the control panel with available bet, spin, sound and info. The game has an autoplay option, which allows you to set limits and stop conditions.
The reported RTP is around 95.73%, although some versions list near 92.79% when accounting for a jackpot contribution. Volatility is high, which means periods of quiet spins are broken by larger payouts when features land. Demo play for the 24 Hour Grand Prix is not available here. Some online casinos and slot sites may offer free play after registration, and Red Tiger Gaming sometimes provides demo on its site.
The controls quickly responded in my test session, and auto spin ran without lag. The betting range is reasonable for players in the UK. I recommend playing this online slot in mid-range rather than as an extreme high-roller, especially with the maximum bet capped at £40.
Our team tested the 24 Hour Grand Prix slot machine to give balanced insights on how the gameplay and bonus features feel in practice.
In testing, stacked cars appeared often enough to provide steady wins, but the real momentum came when two adjacent reels formed a 2×4 Super Wild, pushing payouts far beyond the base game. Race Spins didn’t trigger quickly, yet the rules are clear: three scatters give 10 free spins, with extra scatters adding more, and all low-value suits are removed. When the bonus finally landed after about 150 spins, the absence of suits let car symbols connect more often, and I hit two wins of 100× stake in one round. Jackpots add another dimension, with the progressive pot dropping randomly and the Time Jackpot guaranteeing a payout before its timer expires, which creates room for strategy if you try closer to expiry.
24 Hour Grand Prix maintains a tight focus. No convoluted mechanics or layered side games are distracting from the fundamentals. It simply utilises the narrow structure of a 6×4 structure with stacked symbols, Super Wilds, and a free spins round that is reduced down to all but high-value suits. The pacing is slow, and the features might not reveal themselves quickly. Still, they can yield intense payouts when they appear, further enforcing the high volatility configuration.
This slot suits high-risk fans who like structured play and are patient enough to wait for the bonuses. Casual players can still play 24 Hour Grand Prix for fun in demo slot mode, but its true appeal lies in real-money sessions where the jackpots and volatile triggers bring out the best of its design.
