Koi Trio is a koi-themed video slot from JDB Gaming, free to play here in demo mode. It spins across a 5x3 grid with 243 ways to win at a 97% RTP and medium-high volatility, and is built around three bonus rounds - Treasure, Fortune and Lucky - that JDB designed so they can trigger together as a triple accumulator. Multiplier wilds and a Grand jackpot lift the top payout to 1,800x, all played with virtual credits and no real money.
Game mechanics
Koi Trio pays on a 5x3 layout with 243 ways. Wild symbols substitute for all regular paying icons, and when a wild lands in a winning combination it applies either a x2 or x3 multiplier to that payout.
The game's signature is a triple accumulator: its three bonus features - Treasure, Fortune and Lucky - are designed so they can activate together rather than one at a time, layering free spins, a Hold-and-Win round and reel expansion into the same session.
The Fortune feature holds the game's jackpot ladder, with Mini (x10), Minor (x20), Major (x180) and Grand (x1800) prizes tied to its golden coins and Color Ball Bonus, while four Bonus Buy tiers let you jump straight into the features.
