How wins form

All winning combinations pay from left to right on adjacent reels beginning from the leftmost reel, except certain special symbols. Only the highest winning combination is paid on each pay way.

Symbols and paytable

The top symbol is the golden koi fish: 120, 60 and 30 for 5, 4 and 3 symbols. Then come the sailing ship (100, 50, 20), the golden turtle (60, 30, 12), the money bag (50, 20, 10) and three linked coins (30, 12, 6). A, K and Q are worth 16, 6 and 4; J, 10 and 9 are worth 10, 6 and 4.

These numbers are printed for denomination 0.01 and bet multiplier 1, in credits, and change with your bet.

Wilds and multipliers

Wild symbols appear only on reels 2, 3 and 4 and substitute for all symbols except three special symbols. When the plain wild forms part of a winning combination, it randomly transforms into the 2X or 3X wild. A 2X wild multiplies the win by 2 and a 3X wild by 3; several in one combination each multiply the win.

Three features and combinations

When one or more collection symbols appear, each releases a coin that is collected into its matching pot. A collected symbol may randomly trigger its feature game. Different features can be triggered together to form four combinations: Treasure and Lucky, Treasure and Fortune, Fortune and Lucky, and all three. When Auspice Coming appears, one of the feature games is definitely triggered.

The Treasure Feature awards 8 free spins; score symbols carry a base score and a booster symbol raises the base score until the feature ends. The Lucky Feature also awards 8 free spins; reels can expand up to a maximum of 6 rows, after which each extra arrow symbol awards 1 free spin, up to a maximum of 50.

Fortune Spins and jackpots

The Fortune Spins start with 3 rounds, the grid is divided into 15 independent reels, and the rounds reset to 3 as long as any symbol appears. It ends when the reels are filled or the remaining rounds reach zero. Each time a colour ball appears, the Color Ball Bonus is triggered.

Jackpots are fixed prizes on the jackpot panel and are multiplied by the total bet: GRAND 1,800X is awarded only when the reels are all filled in the Fortune Spins; MAJOR 180X, MINOR 20X and MINI 10X are awarded in the Color Ball Bonus.

Feature Buy

Feature Buy (if available) is for the base game only. Option 1 at 30 times the total bet triggers 1 feature at random; option 2 at 75 times triggers 2 features at random; option 3 at 120 times and option 4 at 300 times guarantee 3 features.

Koi Trio paytable

Numbers in credits printed on the rules page for denomination 0.01 and bet multiplier 1, for 5, 4 and 3 same symbols on adjacent reels from the left; they change with your bet.
