Slot Summary

The Money Tree turns a free-spin trigger into a picking sequence in Lucky Koi. Spadegaming connects its prosperity imagery to the rules: the tree supplies the bonus, and the fish serves as the wild. Separate selections determine the round's length and multiplier, making the reveal before the spins a central part of its identity.
MechanicsSeparate picks reveal spins and their multiplier

Theme & Atmosphere

Lucky Koi uses Chinese prosperity imagery to connect its fish and Money Tree. The tree carries coins and red envelopes, making the bonus source part of the fortune setting.

The fish is more than an animal motif: it takes the wild role, while the tree awards free games. Those assignments tie the game's luck imagery to recognizable actions.

Bonus & Free Spins

Money Tree symbols on the first and last reels trigger the selection sequence. A money-bag pick reveals the free-spin allocation, and a separate coin pick reveals the multiplier applied during the feature.

The selections can award up to 20 free spins and a multiplier of up to x10. Further Money Tree triggers during the feature can extend the round with additional 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 (96.00%), 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.

Questions & Answers

Lucky Koi FAQ

3 questions

No. The koi substitutes for regular symbols, but it cannot replace the Money Tree bonus symbol or the scatter.

Additional free spins retain the multiplier selected at the start of the original bonus round.

Lucky Koi uses 20 paylines across its five reels. Winning positions follow those lines rather than an all-ways payout system.
