The gorilla is the wild symbol and it can land on all reels except for the first. The gorilla will substitute for all of the other symbols, except for the scatter symbol, to help and form winning combinations.
The scatter symbol is a purple gemstone.
There is a Savage Wild countdown above the reels and it will randomly start from 10, 15, 20, 25, 30, 35, 40, 45 or 50. Any wild that lands on the reels during the countdown will leave a leaf icon on that position and increase the multiplier by 1x, up to a maximum of 25x. When the Savage Wild countdown reaches 1 the next spin will trigger the Savage Wild feature. All the positions on the reels with leaf icons will transform into wilds and all the new payouts are calculated. Theoretically, this feature can award you up to 2,500 times your bet!
The free spins are triggered by landing three or more scatter symbols anywhere on the reels. You receive ten free spins during which all of the wild symbols become sticky for the duration of the spins, so by the end of the spins there may be many of them on the reels. Better yet, if you land a wild symbol on the same position as an existing wild then it will increase the payout multiplier by 1x up to a maximum of 25x. You can win 5 more free spins by landing three more scatters on the reels.
Savage Jungle has a top payout of 20x for landing five leopards symbols along a payline. The toucan and chameleon can both payout up to 10x, while the butterfly and flower can both payout up to 8x. A and K can payout up to 7x, Q and J can payout up to 5x, and 10 and 9 can payout up to 3x. The scatter symbol offers payouts of up to 10 times your total bet.
