Thunderhorn Slot


Anyone who has seen the John Wayne classic Hatari will realize that Thunderhorn is an appropriate name for a wild rhino rampaging through an African plain. The main symbol in this slot game is the rhino. Other symbols create the wild African environment include mask, leopard, bongo, bowl and tree. The regular Bally playing card symbols have also been used. Pulsating drum beat audio track completes the African theme.

Important Symbols and Combinations

The highest payout is awarded by the Bonus symbol. The rhino symbol appears stacked on the reels and gets animated in the winning combinations. A rewarding feature in Thunderhorn is that the winning combinations for the main symbols start with two like symbols. The African tree is the wild symbol. It does not award line payouts but acts as a multiplier in the free spins. The Bonus logo activates the free spins bonus round.


Thunderhorn is an all pays slot game that has four rows of symbols across the reels. This gives a total of 1024 ways of winning. The line bet is multiplied by a fixed multiplier of 40 to give the total stake per spin. Therefore with 40 coins wagered you can cover all 1024 paylines. The line bet varies from 0.01 credits to 16.00 credits. Therefore the total bet ranges from 0.40 credits to 640.00 credits, making Thunderhorn attractive to high rollers.

The Auto Play allows up to 25 spins without manual intervention. You have the option of disabling the sound, but the audio track is fast and peppy and it is best to leave it on. The pay table and game rules can be accessed from the bottom toolbar. The pay table is dynamic displays the actual payout in credits for the bet made.

Bonus Rounds

Thunderhorn does not have a bonus round but the free spins round more than makes up for it.

Free Spins

3, 4 or 5 Bonus symbols trigger 8, 15 or 20 free spins respectively. During the free spins, each wild symbol that appears on reels 2, 3 and 4 will randomly multiply the payouts two times or three times. Additional free spins are awarded when Bonus symbols appear on the reels. 2 Bonus symbols award 5 free spins, 3 Bonus symbols award 8 free spins, 4 Bonus symbols award 15 free spins and 5 Bonus symbols award 20 free spins. All these features usually ensure that the total free spins payout is thundering. The feature ends when no more free spins are left.

Top and Secondary Prizes

The top line payout of 600 credits is awarded by 5 Bonus symbols, one appearing anywhere in each reel. Though the Bonus symbol acts as a scatter for triggering the free spins it awards line payouts. The second highest line payout of 300 credits is similarly awarded by the rhino symbol. Because of the 1024 ways, winning combinations occur more frequently and therefore line payouts are smaller than in some other Bally slots.
