Koi Koi Treasure Slot Gameplay and Mechanics

Koi Koi Treasure Base GameThe gameplay in Koi Koi Treasure is quite straightforward, which makes it easy to follow while still offering moments of excitement. The slot is set on a classic 5-reel, 3-row layout with 28 fixed paylines, so you won’t have to worry about adjusting lines — they are always active. Spins flow smoothly, with soft sounds and gentle animations adding to the calm setting. However, the slot isn’t just about looks; it hides several helpful features. Randomly during the base game, you might spot a Mega Symbol, which is a giant 3×3 symbol that covers the middle reels. This can make it much easier to land a nice win. On top of that, Scatter symbols trigger the Free Spins round, where Mega Symbols become guaranteed on every spin. You’ll also find options like a Bonus Bet and Buy Feature, giving players more ways to jump directly into the Free Spins if they want to.

How to Win in Koi Koi Treasure

Here’s a simple breakdown of how to play and boost your chances:

  1. Set Your Bet – Choose your preferred stake between €0.28 and €1,400 per spin. If you want, you can also activate the Super Bet, which doubles your bet but improves your chances of triggering Free Spins.
  2. Watch for Mega Symbols – During base spins, Mega Symbols can appear randomly. These large symbols act as nine regular symbols, giving you more ways to line up winning combinations.
  3. Trigger Free Spins – Land 3, 4, or 5 Scatter elements anywhere on the reels to get 5, 8, or 18 Free Spins. During Free Spins, Mega Symbols will show up on every spin automatically.
  4. Consider the Bonus Buy – If you don't want to wait, you can use the Buy Feature to enter the Free Spins round instantly by paying 56.71x your base bet.
  5. Look Out for Wilds – Wild symbols help complete winning combinations and are particularly useful during the Free Spins level, where they tend to appear more often if you've activated the Super Bet.
