Koi Gate is an Asian-themed video slot from Habanero Systems played on a 5-reel, 3-row grid with 18 fixed pay lines and a theoretical RTP of 96.26%. Expanding Koi Fish Wilds trigger re-spins with doubled wins, and a progressive jackpot can drop at the end of any random spin.
The game is built around the calm of a koi pond: striking colours, a soothing soundtrack and symbols detailed enough to hang on a wall. It is a relaxed slot with one main feature, and the notes below cover the specs, symbols and how that feature works.

The RTP is a theoretical, long-run figure, so it says nothing certain about a single session. See what RTP means for more.
Theme, Graphics and Sound
The Asian influence is heavy and it works. Nearly every symbol could be lifted off the reels and turned into a painting. Whenever a spin wins, cherry blossom petals fall from the tree above the reels, which is a nice touch.
The calming background music suits the theme, and the sound effects add excitement without breaking the mood. Animation is the weak spot: there is nothing moving in the background and in-game movement is bare. Some flowing water or bubbles would have helped.
Symbols and Paytable
Eleven symbols can land, nine on the common paytable and two special ones. The low-paying symbols are the card royals J, Q, K and A. The high-paying symbols are Crashing Waves, Green Bamboo, a Lotus Lily and the Red Gates, which are the highest-paying common icon.
The Dragon is a Wild and substitutes for any other common icon. The Koi Fish is also a Wild, but it can only appear on reels 2, 3 and 4, and when it does it expands to cover the whole reel. Expanding Wilds are a trait of many Habanero Systems games.
Grid, Bets and Pay Lines
The game uses a grid of 5 reels and 3 rows with 18 fixed pay lines that pay both ways. Coin bets run from 0.01 to 0.5 coins. The variance is low, which means smaller wins tend to arrive more often than in a high-variance slot.
Koi Fish Re-spins and the Progressive Jackpot
One re-spin is awarded when one or more Koi Fish Wilds land on the grid. If another Koi Fish Wild lands during a re-spin, you get an additional re-spin, and this continues until no new Koi Fish Wilds appear. Any wins during these re-spins are doubled.
At the end of any random spin, the progressive jackpot can also be won. There is no separate bonus round, which suits newer players or anyone who wants to kick back and relax.

Verdict
