Bonuses in the game

  1. 10 free spins are triggered when three scatters land. During free spins, there is a wild symbol with x2 multiplier. Scatters in bonus games also drop out, there is a chance to get 10 more spins.
  2. Hold&Link is activated with the appearance of 6 or more Bonus symbols (blue ball). The player gets three respins. During such spins, all bonus symbols become sticky. At the end, the winnings are calculated taking into account the total number of pictures with the ball left in place.
  3. Boost (purple ball) only appears on reel 3 in the base game. During respins, it interacts with the Bonus symbol, summing up the winnings on them.

When testing with the minimum bet, the bonus game started after 40 spins.


The Scarab Boost slot has four standard Booongo jackpots: Mini, Minor, Major, Grand. They drop out only in bonus rounds. The size depends on the rate. If the Bonus symbol fills the entire playing field, the Grand Jackpot is awarded. With a maximum amount per spin of $60, its size is 300,000 USD.
