Personal testers’ opinion about Big Kahuna slot

  • Surely the graphic, sound, and overall design of this slot cannot compete with the same attributes of most of the contemporary slots, but for a simple low variance game, it offers good laid-back gameplay, especially suited to beginners. 
  • There are no Free Spins, but there is two lucrative Pick and Click bonus games to compensate.
  • The probability of landing a pay combination with bonus symbols is only 0.37% (i.e. every 267th spin, statistically).
  • The probability of hitting any win is just 17.62%, which is certainly disappointing for this 9 liner. Since there are no Free Spins, a big chunk - 83% of the prize pool is set aside for payment in the usual spins.
  • So, the majority of large payouts are dealt out exactly in the main game. We can only pass neutral advice for fulfilling the bonus requirements as the wagering index for the Big Kahuna slot machine is just slightly above the middle line.
