Tester`s review

Statistically, every 55th spin (1,80%) triggers the bonus feature. If you're missing a lot from that numbers, you should think about shutting down this machine. Usually if it is cold - it stays cold with the increasing the number of the spins. It reserves 46% of the winning pool for the bonus features and 54% to winning in the usual spins. The probability of the hit (any winning) next spin is equal to 26.80%. My biggest winning during the testing has reached 500x. Koi princess slot does not always keep the balance, but still you can try to complete the bonus requirements. Always put bonus bet (on) to get higher RTP (return to player percentage) numbers (from 96% to 96,23%).

Symbols and payouts

Such a grandiose video slot is also suitable for a payout table, which is capable of making good payment even for the pay combination of four identical images. All of them are divided into three categories: thematic symbols, card denominations and special symbols. The thematic signs are considered highly paid, but not so often collected in the pay combinations. But the icons of the cards are a frequent visitor on the reels of the video slot, however, they do not give too many winnings, unfortunately.

  • Wave (Wild) brings from 4 to 500 coins.
  • Princess Koi - from 2 to 400 coins.
  • Lion - from 30 to 300 coins.
  • Frog - from 20 to 250 coins.
  • Coins - from 20 to 200 coins.
  • Card marks - from 5 to 160 coins.
  • In most cases, you need to collect three identical symbols and even more. But for the wave and Princess Koi it will be enough two. The pay combination will be credited if it goes from left to right, starting with the outer reel. Only the biggest payout on the pay line bet is paid. If in one round you managed to collect several pay combinations, then all the payment will be summed up.
  • Wild symbol - the image of a wave is wild symbol that replaces all other images, except for bonus and scatter, and it also independently forms the pay combinations. It appears on any of the reels.
  • Bonus symbol - the image of a dragon in a gold frame is Bonus symbol that opens access to the different bonus games. We should say that it does not form any independent pay combinations, moreover, it can appear anywhere in the playing field.
