SlotRanker Score: 64 — Koi Koi Treasure by Habanero
https://slotranker.com/habanero/koi-koi-treasure#scoreSlot Summary
How It Plays
Koi Koi Treasure uses a 5x3 grid with 28 listed paylines. Regular symbols form line wins while Wild and Scatter Symbols handle substitution and feature access.
The unusual grid event is the Mega Symbol, which can fill a 3x3 area across the center reels and create several matching positions from one symbol.
Theme & Atmosphere
Koi fish place the game firmly within its Asia, Fish and Nature themes, while Flowers and Gems soften the presentation around the oversized center symbol.
Sea, Sun and Moon imagery gives the setting a quiet day-to-night quality. Treasure remains present through the Gems without displacing the Koi as the primary subject.
Features & Win Potential
The Mega Symbol can appear at random and occupy the middle three reels as one 3x3 symbol. Its size gives a single symbol several possible line connections.
Wild Symbols substitute during ordinary evaluation, while Scatter Symbols control entry to Free Spins. Bonus Bet and Bonus Buy provide additional routes into feature-oriented play.
Bonus & Free Spins
Three, four or five Scatter Symbols award five, eight or eighteen Free Spins respectively. The published feature can reach as many as 28 Free Games.
During Free Spins, a Mega Symbol is guaranteed on every spin. That rule makes the 3x3 center block a constant feature element rather than a random interruption.
This game is searched most in Australia, Germany, and Denmark.
