The online 3D slot Princess Koi offers a range of betting options that varies between £0.2 and £200 per spin. Players first discover a tranquil scenery somewhere in the Japanese country side, featuring a waterfall on the right of the reels, and our lovely young princess of the left to cheer us on as we spin. The five most lucrative symbols of this game are the Wild – which represented by ocean waves -, the Princess, the Lion, the green Frog and the set of Gold Coins linked with blue ribbons. The most lucrative is the symbol of the waves, which gives a 500x prize when you land five of them across an active payline. Convert this price in pounds and you end up with a sum of money of £100,000, as long as you had bet the maximum. Then comes the icon of the princess and that of oriental lion who pay 400x and 300x respectively, equivalent to £ 80,000 and £ 60,000 in real money. Choose the Bonus Bet feature that requires put twice your current bet, and you will have more chances to activate random mini-games. Learn more later in this review.
