Slot Summary

Released on April 6, 2018, Koi Kingdom places an unusually high 98.08% RTP inside a conventional five-reel, 20-payline format. BF Games offsets that restrained base structure with Free Spins, a Wild Symbol, Scatter Symbols, and an optional Gamble round after a win. Its medium-volatility profile keeps the focus on a direct sequence of line combinations followed by clearly separated feature decisions.

How It Plays

Winning combinations follow 20 fixed paylines across five reels. The Wild Symbol substitutes for ordinary paying symbols, while the Scatter Symbol handles entry into the bonus.

After a regular win, the Gamble option creates a separate decision: collect the result or enter a double-or-nothing selection game with the current amount at risk.

Theme & Atmosphere

Asia and Fish provide the main identity, with koi imagery placed among Flowers and Nature rather than presented as an aggressive fantasy creature.

The Sea and garden-like setting favors calm natural imagery, which contrasts with the optional Gamble decision and its immediate risk after a win.

Features & Win Potential

Substitution Symbols and the Wild Symbol support ordinary payline combinations without changing the underlying fixed-line format or requiring a separate collection meter.

The Risk/Gamble Double game appears after a win and offers a voluntary attempt to double that result, keeping the choice outside the regular reel sequence.

Bonus & Free Spins

Three Scatter Symbols award 12 Free Spins. Another three scatters during the feature retrigger the round, extending it with an additional set of spins.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (98.08%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
