The Koi Gate Slot by Habanero

The art leans hard into temple-on-a-cliff imagery: a gold-and-red Chinese gate arches over the reels with crashing blue waves and a golden koi swimming up the left side, lotus petals and red lanterns scattered along the borders. Symbol art keeps the theme tight, bamboo, lotus, cresting waves, and red paper lanterns sit alongside ornate carved-stone royals. The whole thing draws on the legend of the Dragon Gate at Lake Dianchi, where koi who leap the gate are said to transform into dragons.

That myth maps directly onto how the Koi symbol behaves. Land one Koi anywhere on the reels and it expands to cover the full reel vertically as a Wild, and the same trigger awards a respin. Any additional Koi that drops during that respin extends the chain again, and there's no documented cap on the retrigger, in theory the sequence runs as long as fresh Koi keep appearing. Every win paid during the respin sequence carries a flat 2x multiplier, so the longer the chain holds, the more aggressively the doubled pays stack.

Free Spins sit on a separate scatter trigger, layering a second bonus path on top of the Koi mechanic rather than replacing it. Above the reels two jackpot meters tick along in real time, a Grand and a Minor, both awarded randomly rather than tied to any in-game trigger. This is the old Habanero progressive structure from before the Race jackpot system existed, and the game was never retrofitted.

The bet design is where this one breaks from almost everything else in the Habanero catalog. There's no 0.10 micro-stake here. The default bet is 5.00, the stake ladder jumps 5 / 20 / 30 / 40 / 50 / 70 / 100 / 200 / 300 / 400 / 500, and the ceiling reaches 90,000 once bet level multipliers kick in, roughly fifteen times the maximum on a typical Habanero release. It's built squarely for the VIP segment, which is an unusual choice for a 2017 game still running on expanding wild mechanics rather than anything fancier. Max win lands at 7,373x bet, which sounds modest until you remember the doubled respins are doing most of the heavy lifting.
