Wolf Prime X UP™ is the latest addition to the X UP™ family of games. All three X UP™ scatters are here, as is the new Wolf Prime Bonus, Free Spins, and the UPSIZER™ feature modifier. Two X UP™ scatters land and combine to increase the Free Spins starting multiplier value. Red climbs the multiplier trail, and blue upgrades all levels top down up to 25x. Cash symbols will have their values collected by a Wolf symbol, should it land on Reels 1 or 5. A Gold X UP™ applies the active multiplier to cash and jackpot prizes in the base game. Free Spins begins with the active X UP™ cash and jackpot prize multiplier applied. Landing X UP™ scatters awards 2+ free spins and 1 X UP™ token . The Wolf Prime bonus is triggered by filling 5 reels spaces above the reels with landed bonus symbols. The Wolf now appears as a persistent expanded symbol on reel 1. Special trophies that land are collected above the reels. The bonus continues until any 3 of a kind trophies have been collected and the associated jackpot prize is awarded.
