Beautiful gemstones and aquatic treasures fill the five reels of Koi Koi Treasure, a serene 5×3 slot from Habanero that blends traditional Japanese aesthetics with high-energy mechanics. This medium-volatility title features 25 fixed paylines in the base game, where oversized “Mega Symbols” can randomly dominate the center three reels to significantly boost win potential. Landing 3, 4, or 5 Scatter symbols triggers an enhanced bonus round of up to 28 Free Spins, during which the engine doubles the active paylines to 50 and guarantees Mega Symbols on every spin.
As part of the Habanero Jackpot Race network, players also compete for a time-sensitive progressive pot that is guaranteed to pay out during scheduled events. This combination of peaceful visuals and a robust “Hold and Win” style of engagement provides a balanced, high-stakes experience for those looking to uncover hidden riches beneath the surface.
Koi Koi Treasure, a June 2024 release from Habanero, invites players into a tranquil underwater world where traditional Japanese aesthetics meet modern slot mechanics. The game features a 5×3 reel layout framed by lush aquatic vegetation and a meditative soundtrack. While the visuals are peaceful, the gameplay is designed for high engagement, utilizing 25 fixed paylines in the base game that expand during bonus features.
The symbol set is a mix of thematic icons and treasures. High-value symbols include silvery koi fish and lotus flowers, while lower-tier wins are formed by shimmering gemstones. This medium-volatility title offers a massive betting range, typically starting at $0.28 and scaling up to $1,400 per spin. A Super Bet feature is available to double these stakes, increasing the likelihood of triggering the game’s primary features.
The standout mechanic is the random Mega Symbols feature. During any spin, the middle three reels can merge into a 3×3 block, revealing a massive version of any symbol except the Scatter. When 3, 4, or 5 Scatters land, players are awarded up to 18 free spins. During this bonus, the “Line Boost” mechanic doubles the paylines to 50, and Mega Symbols are guaranteed to land on every spin. Additionally, the game is linked to Habanero’s Jackpot Race network, a time-based progressive system where the pot is guaranteed to trigger before the end of a scheduled race.
With a 96.84% RTP and a 1,682x max win, it balances steady play with the excitement of a competitive progressive prize. Habanero also offers several other game types, many of which we have reviewed on this website. So check out our look at the Golden Taj Mahal game, or the Safari Rumble online slot.
