Koi fish swim through Koi Trio, a JDB Gaming slot played over 243 ways on a 5x3 grid with a 97% RTP and medium-high volatility. Its three bonus rounds, Treasure, Fortune and Lucky, can trigger together, and the Grand jackpot inside Fortune sets the top payout at 1,800x.

Game mechanics

Each spin pays across 243 ways on five reels of three rows. A wild substitutes for every regular paying icon, and when it is part of a win it multiplies that payout by x2 or x3.

JDB built the three bonus features as a triple accumulator: Treasure, Fortune and Lucky can activate at the same time instead of one after another, stacking free spins, a Hold-and-Win round and reel expansion on top of each other.

The jackpot ladder sits in Fortune, with Mini (x10), Minor (x20), Major (x180) and Grand (x1800) prizes linked to its golden coins and the Color Ball Bonus. Four Bonus Buy tiers give direct access to the features.

Features

  • Wilds with Multipliers. Substitute for all regular paying icons and add a x2 or x3 multiplier to any win they help form.
  • Treasure Feature. 8 free spins built on base scores, with Purple and Purple Koi coins adding score values between x58 and x588.
  • Fortune Feature. A Hold-and-Win round with three lives and 15 reel positions. Golden coins, Color Ball symbols and the Color Ball Bonus subfeature drive it, and it holds the Mini (x10), Minor (x20), Major (x180) and Grand (x1800) jackpots.
  • Lucky Feature. Opens with 8 free spins. Green Koi and Arrow symbols push the reels up to a maximum of 6 rows, and reaching full height adds extra spins, capped at 50 in total.
  • Bonus Buy. Four tiers: x30 the stake buys one random feature, x75 three random features, x120 all three features, and x300 a combined Free Spins and Hold and Win round.

How to play the free demo

  1. When a wild joins a win in the Koi Trio demo, check whether it added x2 or x3 to the payout.
  2. Watch which bonus lands: Treasure and Lucky each start with 8 free spins, Fortune is the Hold-and-Win round with the jackpots, and more than one can fire at once.
  3. Open the Bonus Buy menu to pick one of its four tiers, from one random feature up to Free Spins combined with Hold and Win.

Why try the Koi Trio demo

A triple accumulator is hard to picture from a description, and the demo lets you see what happens when Treasure, Fortune and Lucky trigger in the same spin. Inside those rounds, the Lucky reels grow toward 6 rows while the Fortune round's three lives count down.
