Rich in 3D graphics, animations, and special effects, Oonga Boonga slot has five reels, 20 paylines, and various bonus features. The Blue Gem online slot’s bonus features include Cascading Reels with Chain Reactions, Wild and Scatter symbols, and a gamble game.
The paylines are fixed, which means all lines are active on every spin. However, the coin denomination and the number of coins bet per line can be adjusted to suit players’ preferences.
One of the game’s special effects is a medicine man wearing a mask, who stands on the left of the reels. The medicine man responds to the game as it unfolds, and cheers on wins or commiserates losses.
Symbols and Cascading Reels
The Oonga Boonga slot reel symbols all appear to be carvings on blocks of stone in various colours. Tribal in design, they feature different birds, as well as people wearing feathered headdresses.
The game’s bonus symbols appear as a question mark and as the relief of someone’s face in gold.
The Cascading reels are noticeably different to those of most other online slots. Instead of featuring regular reels on which symbols spin, the symbols drop down into rows from the top of the screen.
If a spin of the Oonga Boonga slot produces winning combinations, those stone blocks will vanish, and any symbols above them will drop down further to take their place. New symbols will then drop down from the top of the screen.
If new winning combinations are formed, the process will be repeated, and will continue until a Chain Reaction fails to produce a winning combination. Any winnings produced in this way will be multiplied by a 1x, 2x, 3x, or 5x multiplier.
Oonga Boonga Wild Symbol
The question mark symbol that appears on the Oonga Boonga slot reels is the Wild symbol. Its appearances are limited to the second, third, and fourth reels.
The Wild has the power to substitute for all the other reel symbols except the Scatter. It will substitute for other symbols if it can help form a winning combination.
Oonga Boonga Scatter and Free Spins
The gold block is the Oonga Boonga slot Scatter symbol, and its appearances are limited to the first, second, and third reels. The symbol activates the online slot’s free spins round, known in the game as Free Drops.
At least three gold blocks are needed to activate the round, and they can do it from any position on the reels. They do not need to appear on a single payline. The round offers as many as 10 free spins.
Oonga Boonga Gamble Feature
The Oonga Boonga slot Gamble Feature, known as the Double Up Game, can be played whenever a payout is won.
Played in a second screen, the game features the masked medicine man seen next to the reels in the base game.
Players are shown the result of the previous coin flip, and must guess the result of the next flip of the coin. If the guess is correct, the winnings are doubled.
