How It Pays – Reels / Paylines / Bets
Koi Falls plays on a 5×3 grid with 9 paylines. Wins run left to right across at least one line. Bets range from €0.90 to €900 – note the non-round €0.90 floor if that matters to you.
Premium symbols (golden frogs, ingots, lotus, coin necklaces, Pan Chang knots) pay 25x to 500x your stake for 5 of a kind. Royals pay 10x to 15x for the same. Lower-value symbols need 3 of a kind; premiums need only 2 to trigger a win.
The math is clean: 96.5% RTP, low volatility, 500x max win. Expect steady small-to-mid wins rather than dry spells punctuated by shock payouts.
Wild Symbol – Reels 2 / 3 / 4 Only
Wilds appear only on the three middle reels and substitute for any regular pay symbol to complete or boost line wins. Trigger → lands on reel 2, 3, or 4 → fills a gap in your line → win improves or completes. Outcome: no pure wild wins (wilds have no standalone value), but they’re your primary line-completion tool.
A win is not guaranteed when wilds land – you still need matching symbols across at least one payline.
Scatter Symbol – All Reels / No Substitution
Scatters (two golden koi and a coin with a square hole) land anywhere on all 5 reels and do not substitute for wilds. Land 3+ scatters anywhere in view to trigger a payout.
| Scatter Count | Payout |
|---|---|
| 3 in view | 2x stake |
| 4 in view | 10x stake |
| 5 in view | 50x stake |
Scatters pay independently of paylines – they work anywhere on the board.
Spin Speed / Autoplay
Three spin speed tiers: default (leisurely), medium turbo (balanced pace), and maxed turbo (rapid fire). The medium setting lets you savor each spin while clearing plenty of spins per minute. Note: faster speeds cut the spin melody short, which some players find unsatisfying.
Autoplay runs 50 to 999 consecutive spins hands-free. Pair it with the default or medium speed for a meditative session.
Theme / Presentation
Two charming koi carp drift above the reels against a hazy golden stream. The animation is hypnotic and can distract from gameplay – coins shower down whenever you win. The paytable is steeped in Oriental symbolism: frogs, ingots, lotus flowers, lucky coin necklaces. A steady river ambience anchors the soundscape, punctuated by a traditional Asian melody on every spin and win.
The mobile-first portrait layout keeps the action centered and intimate.
What You Don't Get
No bonus rounds. No free spins. No bonus games. This slot is deliberately stripped down – what you see is what you get. The game leans hard into low-volatility, steady-stream gameplay rather than feature complexity.
