There's a wide variety of betting options available. The wager can be as low as $0.01, for one active payline, and go up to $125 per spin.

The low-value symbols match the game's background and feature a dragonfly, a turtle and a frog on a lily pad. On the other hand, the top-paying ones feature elements from Japanese culture and, of course, the Koi fish itself.

The game logo serves as the game's Wild and can substitute for all other symbols, except the Scatter. Land at least three Scatters and you'll have the chance to choose one of the two Scatter bonuses.

The first one is the Free Spins feature, where you can win from 10 to 30 spins in combination with a multiplier going up to 5x. Land additional three Scatter while the feature is active to retrigger the game.

The second one is the Koi Bonus feature, where you'll pick from 3 to 6 Koi fish and even may be awarded additional picks.

The January 2014 release comes with medium volatility, so expect well-balance payouts. The games expected return to player is 96.47%
