Most of Rival's new game releases are of the 50 paylines version, which isn't to my liking at all, because these games need double or more of the minimum bet size to play it. My preference has always been the 15 and 20 paylines versions, for any game, and anything requiring more than this are usually kept aside, to be played only when I have sufficient money, or for any other specific reasons. Hence, games like Mystic Wolf have never become a hit with me, or for me. All my top favourite games are of 20 paylines and less.
The Wolf is the Wild symbol, it doesn't pay anything for itself, but multiplies 5x all wins with it in the base game. It substitutes for other symbols except the Scatter symbol, but doesn't become stacked or expanded. In my books, this is still a dumb Wild symbol. The Feathers is the Scatter symbol, yet another dumb symbol that doesn't pay anything for itself, and getting 3, 4 or 5 of these Scatters trigger 7, 15 or 50 free spins, without any multiplier, but with a Mystic Wolf Super Round, whereby the Wild symbol pays 10x for any wins with it. And of course, the Free Spins game cannot be retriggered. During the free spins, getting 3 or more of the non-paying Bonus symbols trigger a Lunar Phase Bonus Round, whereby matching any Lunar symbols wins a cash prize.
There is also a Jackpot prize that can be randomly awarded in the base game and during the free spins too, but is stated as more likely to occur in the Free Spins game. What this means indirectly, is that the Free Spins games may not pay as good as it should, because there is this extra jackpot prize to be won, so better expect to get less than favourable payouts from the Free Spins game! As for the other symbols, the Diamond pays 5000x, the Wolf Face pays 700x, the Howling Wolf pays 500x, and the others pay from 350x to 50x, all per line bet for 5 of each kind. An average paytable, because the Wild, the Scatter and the Bonus symbols don't pay anything for themselves.
