What Is Thunderhorn Slot Machine?

Thunderhorn slot machine is developed by Bally, which is owned by SG Digital, just like its sister company WMS. (You can remember WMS from Reel Em In slots series.) Thunderhorn started as a physical game cabinet in land-based casinos and its online version is developed later by Bally, after the game became popular. The name is a reference to the horn of a rhino and the theme of the game is nature – wild animals.  Thunderhorn slot has the following features:

  • The game area is a 5×4 grid. There are 5 reels and each one can hold 4 symbols.
  • Thunderhorn online slot contains 1.024 betlines. However, it still pays only from left to right.
  • There is no fixed or progressive Thunderhorn slot machine jackpot. Thunderhorn pays big (just like Starburst) but does not include a jackpot prize.
  • You can play with real money or try Thunderhorn free slot game without spending a penny. The game comes with a demo version that contains 10.000 complimentary coins.
