24 Hour Grand Prix Review

The layout of 24 Hour Grand Prix comprises of 6 reels and 4 reels allowing for 24 symbols to land per spin. You have 30 fixed pay-lines to win from by matching 3 to 6 symbols on any of them. These must be landed from left to right starting from the leftmost reel. You can use wagers in the range of 0.10 and £200 to play this jackpot game with progressively increasing rewards. It has a high level of volatility and an RTP of 93.79%. The RTP includes the base return to player and the jackpot contribution.

The features in the slot include the 2×4 Super Wilds of 5 different wild symbols, which give you payouts too. There are free Race Spins with premium and wild symbols only and 10, 15 or more can be won by a player. There is a Gamble Wheel feature that lets you relish in higher sums if you want to risk. The central attraction is the Jackpot feature with 3 progressive jackpots. These are the Daily, Hourly and Big Drop Jackpot.

The jackpot feature can activate with 3 or more Jackpot scatters in a spin or by activating a modifier. Wagers of £4.00 and above qualify you to take part in the contest for the 3 jackpots. The max win per spin in the game is 2166.3x times your bet. The 3 progressive jackpot, of course, can ensure you significantly larger payouts.

The Design

The graphics are in the car racing theme with 5 cars used as premiums and wild symbols and the 4 card suits. You will see them on the grid with a race track as a background. On the left, on a green background are displayed the 3 progressive jackpots. The largest one – the Big Drop is on top and a man covered his face with a hat above it. The card suits are stylishly designed and in darker colours. The cars look authentic and have the glamour of real ones.

The soundtrack includes mainly guitars. It is very energising and at the same time laid-back. It mixes with the sounds of racing cars and the applauding audience. The Race Spins play with more dynamic and exhilarating guitar soundtrack. During them, the wins are usually larger and you will have longer pauses for celebrating them.

Overall, the colours are not too bright and rather darkened. The visual and sound performance is great. It is spectacular and has full of adrenaline racing spirit. The features and gameplay immerse you into the theme very successfully.

24 Hour Grand Prix Gameplay

The pay-table includes 4 card suits and 5 racing cars. The wild symbols are 5 and they correspond to the 5 car premiums. There is a Race Spins symbol, which acts as a feature trigger. The Jackpot scatter activates the Jackpot feature.

Landing 3 to 6 of a kind of the low-paying or premium symbols in a spin on any of the 30 pay-lines from left to right results in a win.

The low-value card suits have different payouts each. The green clubs return 0.10, 0.30, 0.40 and 0.70 times your bet. The dark yellow diamonds grant 0.10, 0.40, 0.50 and 1 time your stake for 3, 4, 5 and 6 symbols on a pay-line. The red hearts pay 0.20, 0.50, 0.70 and 1.40 times your bet for 3 to 6 symbols in combinations. The black spades return 0.30, 0.70, 1 and 1.70 times your bet.

The premiums are 5 racing cars. The green one gives you 0.50, 0.80, 2 and 3.80 times your bet for 3 to 6 symbols. The yellow car returns 0.70, 1.20, 3 and 5.70 times your bet for 3, 4, 5 and 6 on a pay-line. The white car grants 0.90 to 7.60 times your stake.

The red car has a payout of 1.10, 2, 5 and 9.50 times your bet for 3, 4, 5 and 6 symbols on a line landed from left to right. The most rewarding of all is the light-green car with red. Landing 3, 4, 5 and 6 of this car on a pay-line results in 1.30, 2.40, 6 and 11.40 times your bet respectively.

The same racing cars with the word ‘WILD’ itself on each are the 5 wild symbols. They substitute for all other paying symbols and have their own payouts as well. Landing 4 or 6 of the same wild symbol gives you 2.30 and 35 times your stake respectively.

24 Hour Grand Prix Features / Bonuses

There are many extra features in 24 Hour Grand Prix that ensure more chances for wins. One of them is Super Wilds. It triggers when you land 2 adjacent reels filled with the same premium symbols of one of the 5 racing cars. Then, an animated 2×4 Super Wild appears on the places of these 2 reels. You will then receive the relative payout as wilds also give you cash wins.

The Race Spins symbol with the gold cup plays a special role in the game. Landing 3 of it on the same spin anywhere on the grid triggers 10 Race Spins. In case you get more than 3 Race Sins symbols on the same spin, each extra one gives you 5 more Race Spins – 15, 20, 25 and so on. During these spins, which are all free, you will play with the 5 premiums of the 5 racing cars and 5 wilds only. The low-paying card suits won’t land in the Race Spins. This lets you win from better combinations from the highest-paying and special symbols.

The third modifier in 24 Hour Grand Prix is the Gamble Wheel feature. You can take advantage of it after every winning spin in which you have won over £0.10. Simply press the ‘Gamble’ button that becomes active immediately. You will move to a screen with a wheel with green and red sections. A ladder is placed on its left with progressively increasing amounts displayed on it. When you press the minus button, this increases the red section and your odds of winning. The plus button does exactly the opposite.

After every win, you can continue to gamble until you lose. You will be progressing on the ladder with larger cash rewards as you continue winning. Additionally, with each step, the green or red section will either increase or decrease as well as your odds for wins. When the pointer stops on a green segment you win, if it lands on a red one, you lose and exits the Gamble feature. You can use the ‘Collect’ button at any stage to get your winnings. You cannot use the Gamble feature during autoplay. Its results are entirely random and its RTP is 94%.

The highlight in the slot is the Jackpot Game, which you can trigger with 3 or more jackpot symbols. The latter can happen also by activating any game feature. You will then spin the jackpot wheel to determine which of the 3 progressive jackpots you will win. This feature triggers by chance and through it, you can win one of 3 progressive jackpots:

Daily Drop Jackpot – you can hit it by the time and day displayed. Its seeded amount used after the jackpot is won is £5,000.00;

Hourly Drop Jackpot – you can hit by the time displayed. Its starting value after a lucky player grabs it is £50.00;

Big Drop Jackpot – you can win at any time and it is the most valuable and largest reward of the three. Its seeded amount after a player wins it is £100,000.00;

All wagers from real play over £2.66 take part in the contest for triggering and winning one of the 3 jackpots. In practice, this means play with wagers of £4.00 and larger to be eligible. All bets of £4.00 and above are used to increase the jackpots’ amounts. You see them growing at all times displayed on the left.

The Conclusion

For all fans of car racing and adrenaline sports, 24 Hour Grand Prix is fresh, inspiring and a superb game. There is are 2×4 Super Wilds, free Race Spins, a Gamble and a Jackpot feature with 3 progressive jackpots. These are enough reasons to fall in love with this fast-paced video slot.
