Koi Gate in detail
Koi Gate is a Habanero slot released on 12 February 2017, drawing on the legend of the carp that swims up the waterfall and becomes a dragon. The grid runs five reels by three rows on 18 paylines evaluated in both directions, left to right and right to left. For the same number of lines, that bothway mechanic doubles the opportunities to form a combination.
The game carries two wild symbols. The koi is an expanding wild that appears only on reels 2, 3 and 4 and unfolds across the full height of its reel. The dragon acts as an additional wild. Both follow the bothway logic and take part in combinations read in either direction.
The mechanic that really sets Koi Gate apart is the respins. Every koi symbol that appears awards one free respin. If a new koi lands during that respin, another respin is awarded, and so on. Habanero states explicitly that these respins are not capped: the chain continues for as long as the symbol keeps appearing. The studio further specifies that a x2 multiplier applies during this phase. That combination of uncapped respins and a multiplier is the game's main lever, in place of a conventional free spins mode - Koi Gate does not have one.
Habanero rates Koi Gate high volatility on its official sheet and states a maximum multiplier of x480. Several independent databases classify the game differently, as low volatility, a common divergence when the rating comes from session measurements rather than from the studio's own parameters. The official sheet remains the reference.
The return to player exists, as across the whole Habanero catalogue, in several configurations offered to operators, sitting around 86%, 92%, 94%, 96% and 98%. Independent databases frequently record a figure close to 96.26% on distributed versions. The casino's paytable shows the rate actually running.
The studio lists several operator options on this title: SuperBet, a Buy Feature function, the Jackpot Race tournament system and the WinReplay win playback. Whether they are present depends on the casino. The recorded betting range runs from 0.18 to 900 euros per spin. The game is built in HTML5 and runs in a browser on phone, tablet and desktop, with no download involved. The minimum stake follows from the line count, each of the 18 lines being covered at least once.
Koi Gate therefore reads as a chain machine rather than a tiered one. Each koi that lands may award nothing more than a single respin that goes nowhere, or open a sequence that extends spin after spin. That uncertainty about how long a sequence will run, more than the stated ceiling, is what the title is offering.
