The game is played on a standard 5x3 board with 243 ways to win, so any adjacent combination of symbols starting with the leftmost reel will be a winning one. If you get a full board win, all unique combinations pay. The minimum bet per spin is €0.10, which is very affordable for a game with so many paylines, while the maximum is €100. Main game and paytable There are 12 normal symbols in the paytable plus the Scatter and the Wild, and the symbols are divided into two groups of six. The low-win symbols can only give you more than your bet per spin if you land five-of-a-kind, but it's interesting to see that these prizes can go up to 4x your bet, which is rare for low-win symbols. The high-win symbols progress nicely from 6x to 15x win for five-of-a-kind, though half of these symbols won't be able to give you your stake back when you land three-of-a-kind. This is paytable that's heavily biased towards big wins, and small ones won't get you very far. Wild is also a paying symbol, but only if you land all five, in which case you'll get 15x your bet. In the main game, there's always a random chance of one or more of your reels becoming fully Wild as the Mystery Wild Reels feature triggers. Up to four reels are transformed into Wild reels. Bonus features Three or more Scatters trigger the bonus game. Landing five Scatters will also get you 200x your bet, which is probably the best prize in the game. When you trigger the bonus game, you will be given a choice of three different free spins games types, with three different win multipliers, stacked symbols and numbers of free spins. The volatility will be highest if you choose 6 free spins with a x5 Wild win multiplier, medium if you choose 10 spins with a x3 multiplier, and lowest if you choose 15 free spins with a Wild win multiplier of only x2. The stacked symbols will be different, though this doesn't matter that much as they're all similar, with top prizes of 10x, 12.5x and 15x for Low, Medium and High variance game types respectively. It seems the High variance free spins game offers best value, especially as three or more Scatters that land during free spins trigger a random number of additional free spins. You do want this to happen while you're in the High variance game. Any Wild that lands during the free spins will trigger the Walking Wild feature, and will move one step to the left with each spin until it falls off the board. Every Wild walks individually. Riders of the Storm Slots RTP Theoretical return to player (RTP) is decent enough, 96.15%, so no player should have a problem with this. Most modern slots pay the same as Riders of the Storm. Perhaps if you always choose the best-value free spins game type you can increase this a bit. Conclusion While this game doesn't really have any standout features you'd remember it for, it's actually a very good game that does everything right. The graphics are very good, so is the RTP, and the free spins game is offering an interesting choice of variance. Overall, the variance of the game seems to be a bit high, so it makes sense to push it a bit further by choosing the High variance bonus game, and the Low variance would just eliminate any chance of winning big.
