Let me give you an honest opinion on this slot game after having played it for a few hours. This is a 2018 release by Red Rake Gaming and it’s themed around Formula 1 racing, and you’ll see all the symbols that depict this theme. Graphics are excellent, and the bonus features make this game very interesting to play as there’s always something new going on. Theoretical return to player (RTP) is a bit low at 95.10% and variance is medium. Main game and paytable The game is played on a 5x3 board with 30 paylines. The paylines are fixed and the minimum bet per spin is €0.30 while the maximum is €60. There is little flexibility regarding the bet choice, and there are actually only 12 bet values to choose from, which will be annoying to some players, and will also make it less possible to use betting strategies on this slot game. There are four Racing Helmets that represent the low-value symbols, and they pay 5x your bet for five-of-a-kind so they’re far from insignificant. The three medium-value symbols all pay 10x for five-of-a-kind and 1x for four-of-a-kind, and the two Race Drivers pay 30x for five-of-a-kind and 3x for four-of-a-kind, and these two symbols may appear fully stacked on the reel. What all this means is that in this game you are basically forced to get five-of-a-kind wins or you will barely manage to get your stake back, but these five-of-a-kind wins offer good value. Crucially, the most valuable symbols can be fully stacked so it’s possible to get multiple winning paylines. There is also a Wild symbol that pays a great maximum prize of 100x your bet. Gasoline Can is a special symbol that pays scattered and pays 1x prize for three of them, up to a maximum of nine, which is worth 100x your bet. When Race Drivers appear fully stacked on reels 1 and 5, Speed Run Feature will be triggered. Wilds will be scattered randomly on the board, and this has the potential of giving you numerous winning paylines. When you land five Piston symbols on your board, one on each reel, you’ll trigger the Sticky Pistons Roulette feature. You’ll get three spins of the wheel and can win a nice prize on every spin. If you landed only three or four Pistons you will always get a re-spin to help you win that fifth Piston and trigger this feature. Bonus features While Speed Run and Sticky Pistons Roulette may be considered bonus features as well, they belong to the main game mostly, and the real bonus feature here is the free spins game. You need to land at least three Trophy Bonus Scatter symbols on your reels, and you’ll get 12, 16 or 24 free spins for three, four or five Scatters respectively. If you land more Scatters during the feature you’ll get some more free spins, but the number will be reduced to 6, 12 and 18 free spins respectively, because by that time you will have triggered the maximum win multiplier. Each winning spin during the free spins feature increases the win multiplier, up to x5, so this can get very rewarding, especially if you re-trigger the free spins. Conclusion Speed Heroes is a quality game with three bonus features, with scatter wins and stacked symbols, and this game can therefore pay in many different ways. Theoretical payout is a bit low but this game can still play well in individual playing sessions as the paytable is quite rewarding for five-of-a-kind wins, and there are bonus features that help you get more wins too, and the free spins game has a x5 win multiplier. During the free spins game, a Race Driver five-of-a-kind might be worth 150x your bet, and this represents excellent value. That’s why you should play this Red Rake Gaming slot.
