Why this score

Slot Summary
How It Plays
Regular combinations pay across 243 ways from left to right, while purple, gold, and green coins feed separate meters above the reels. A completed meter opens its associated feature.
The meters complete independently, so the next event may contain one feature, a pairing, or the full trio. This keeps attention on three collection states during otherwise conventional spins.
Theme & Atmosphere
Fish, Asia, and Fortune meet through the three koi, which represent separate collection paths. Their colors help distinguish the Treasure, Fortune, and Lucky meters during play.
Sea imagery supports the koi subject, but the setting is secondary to the fortune symbolism. Each fish corresponds to a different way of changing the bonus sequence.
Features & Win Potential
Treasure awards Free Spins and lets special koi coins raise a base score that remains at its new value for later qualifying coins during the round.
Fortune uses Hold and Win play. New symbols lock into the grid and restore the remaining lives, while filling every position awards the x1800.00 Grand Jackpot.
Lucky changes the reel set during Free Spins. Green koi and arrow symbols expand individual reels, and a fully expanded reel can convert later arrows into additional spins.
Bonus & Free Spins
The Bonus Game can contain one feature or several connected features. Treasure and Lucky can combine score growth with Reelset Changing, while Fortune can add a subsequent Hold and Win stage.
Four fixed jackpot levels sit inside the Fortune route. The smaller levels can come from the Color Ball event, while the Grand requires a completely filled grid.
