The paytable provides incredibly modest prices for symbols of letters and numbers, but payouts obtained for matching combinations with symbols of crystals can become amazing, not only because of good prices of these symbols but because may also appear stacked on the reels, and I personally would say that it is not uncommon to see combinations of 5 of a kind of these crystals symbols stacked on several or all the 5 reels. Here another completely original feature arises, the purple crystal that only generates hits when the bet is equal to or greater than 200 credits, if the bet is under this no winnings are generated with the appearance of these specific symbols aligned, so it can be concluded that this game is mainly aimed at highrollers.
Finally the round of free spins is activated with just the appearance of one wild symbol and the row where it is placed on determines the number of free spins since during each free game the symbol "W" stays in place and the arrow under it is stretched down and free games are completed when the tip of the arrow touches the bottom of the respective reel, additionally for each spin multiplier wild increases in 1x, therefore the maximum multiplier is 4x, but the maximum of free spins may vary depending on whether new "W" symbols appear, ahh, and if there are several simultaneous wilds their multipliers are combined and your hit may derive a big win; this feature has also given me several big wins during my playing time. On the other hand, as nothing is perfect and because the game needs to be also profitable for the casino, we will see long streaks of spins with small or no gain, mainly lines made with symbols of letters and numbers, but overall this slot has a high potential but I recommend playing with a good amount of credits in your account that allows you to scale the bet to take advantage of special features of this volatile game. Good slot!
