The 24 Hour Grand Prix slot comes with 6x3 reels, with 30 active lines. Plenty of features await the player inside, ranging from stacked wild symbols, mega symbols, symbol removals, free spins, and more.
With a very interesting retro vibe, 24 Hour Grand Prix gives the player a total of five themed symbols, which show racing cars of the past. These can be both regular and wild symbols, and they will form their own combinations either way. The low value symbols are represented by the usual card suits, so there are four of them. The Race Spins logo is the only additional feature symbol.
The base game is a rather simple affair. Even the Wilds you’ll encounter in the game aren’t very common, since there are no single tile Wilds. Instead, the Wilds can be any of the high-paying symbols as long as they appear stacked on 2 touching reels. When that happens, the symbols change into a Colossal Wild and act accordingly.
Although this sounds rather difficult to activate, it was actually more common than you’d think. I would say you’ll see one every fifty or so spins. When it shows up, its effectiveness is debatable. It can appear on reels 1 and 2 just as likely as it’ll show up on reels 5 and 6.
The Colossal Wilds mechanic is also active during the base game, where it has some other changes to the gameplay. Activating the Free Spins mode simply requires 3 bonus symbols on the screen. Once the bonus game starts, it’s not possible to win additional spins.
During the Free Spins mode, the low-paying symbols are absent. Instead, the player is only playing with the high-paying symbols. This obviously makes it more likely to get a natural win, but it also makes activating the Colossal Wilds feature a real possibility.
Summing up, we can conclude that retro motives do not fade into the background, but only increase their popularity. Even though the graphics are made in the old-fashioned style, they are rendered well. Original bonus features and high payouts will appeal to most players.
