Game Symbols
An image of a verdant forest with the word "Wild" written in capital letters is the Wild Symbol. It acts as a replacement for everything but the Scatter and can appear anyplace besides the leftmost reel.
An arbitrary diamond represents the Scatter Symbol. You'll win some free games if you get 3 or more of these. You will be awarded 10, 15, and 20 free spins for landing 3, 4, and 5 scatters.
Reels 2, 3, 4, and 5 may, at random, include symbols with 1, 2, or 3 yelling gorilla heads. Each of them stands in for the standard gorilla. Multipliers for one-headed, two-headed, and three-headed symbols are 1, 2, and 3 times their respective base values, respectively. When a golden gorilla contributes to a win, the multipliers are activated.
Free Spins
If you get at least 3 Scatters, the bonus round will begin. The first level is a landing zone for all the golden gorilla heads. You'll advance to the next level when you gather 40 normal gorillas and golden gorillas. At this point in the game, golden gorillas can only represent multipliers of 2x and 3x.
Once you've landed an additional 40 gorillas, you'll be able to access the third level, where only 3X golden gorillas will emerge. Every time a player advances to a new level, they receive 3 additional spins without having to spend any extra money.
During the bonus round, hitting 2, 3, 4, or 5 Scatter symbols awards 5, 10, 15, or 20 more spins. The round ends when the player uses all their reels for the bonus.
Bonus Buy
Paying a certain amount can fast-track you to the bonus rounds with free spins. Just pay 80x the bet, and the feature is all yours.
