Rumble Rhino’s is set in a village near the savannah. The small village huts are set into a landscape with a rocky mountainous backdrop under golden evening skies. An African style drum beat plays repetitively helping to set the scene. Within the reels the symbols are pictures of animals or colourful decorated letters of African design. In the free spins, the arena remains the same but the atmosphere turns to night and the drum beats intensify.
The game’s theme also extends to the symbols and reels. There are seven higher value theme related symbols including a rhino, gorilla, cheetah, zebra, large bird and a snake. The lower value symbols are the royals A, K, Q, and J. The rhino doubles up and acts as the wild. In addition, there is a mystery mask symbol and a bonus symbol.
There are several bonus features in Rumble Rhino that will help you to win big.
Beforehand, it is worth mentioning the alternative feature symbols that can help contribute to wins. As already mentioned, the rhino also acts as a wild. Furthermore, all the animal symbols can land as a mega symbol within reels two to five. Mega symbols have a size of 4x4 and can land partially or in full across the central reels. Wherever the mystery mask symbol lands it will randomly change into a higher or lower value symbol of the same type. Mystery masks can also appear as a 4x4 mega mask and this can only land in full on the reels, not partially.
There is one more symbol to note. This is the bonus symbol that kick starts the bonus game. Land a bonus symbol on reel 1 and 6 simultaneously and you will be taken to a screen with a grid of 4 x 6 diamonds. Under the diamonds are the different types of options you can play in the bonus free spin feature. These options include Rumble Spins, instant win cash prize, and 10, 15, 20 or 50 free spins. Keep selecting the diamonds until you match 3 of the same options that determines the bonus feature game that you will play. For each feature of the bonus game the number of paylines are reduced to 40.
During the bonus game the instant win will immediately payout a cash prize. The free spins options are 20 free spins with a x2 multiplier, 15 free spins with a x3 multiplier, 10 free spins with a x5 multiplier, 50 free spins with a multiplier that increases by x1 with each win, and 7 free spins with locked wilds and a multiplier that increases by x1 with each win. Furthermore, during this final feature, each mystery symbol that lands will award an additional spin.
