If you prefer your online slots experience to involve wild animals and jungle locations then this release from Ainsworth Gaming might fit the bill; it’s full title is Big Thunder King Strike and it comes with a free spins round and some jackpot prizes. Big Thunder is a five reel slot with three rows and up to thirty paylines; entwined around those purple reels is a green vine which has somehow encroached upon the action from the gloomy jungle scene in the background.
