Online Slot Reviews: King of the Jungle & Flamenco Stacks

King of the Jungle

The online slot game King of the Jungle by Ainsworth features an entertaining jungle theme and a frequent free-spin bonus, boosted by a primary-game hold-and-re-spin feature.

The base game is a five-reel, 25-line slot. The main bonus is triggered by three scattered gorilla symbols. When any two of the scatter symbols land during any paid game, the Second Chance Respin feature is triggered. The two gorilla symbols hold in place as the reels re-spin with only scatter symbols enabled, giving the player a second shot at triggering the bonus.

The bonus awards 10 free games. During the free-game feature, wild symbols carrying multipliers of 3X and 5X appear on reels 2 and 4, respectively, multiplying any wins including those symbols by three or five. Two or more gorilla symbols on a free spin award five additional free spins.

Also during the free-games feature, if the “Gold Gold Gorilla Eyes” symbols appear stacked in all three positions on any reel, it triggers one of the four bonus awards displayed on the screen—a Mini award of 100 credits, a Minor award of 400 credits, a Major award of 1,000 credits, or the top Grand award of 15,000 credits.
