If you play a classic or luxury version, the main rewards of the game are very similar, although the luxury version is more comprehensive. You will trigger this by clicking 3 gold coins on the reel.
The classic version allows you to choose one of the five koi - this will let you know where the slot's title comes from! Each of the five koi looks the same, but with a different colored background. Your first choice is to have a huge 25 free games, each of which will see any victory using the Koi wild symbol multiplied by 2x, 3x or 5x. In addition to the multiplier increase, the other four options can see the reduced number of free spins available. The minimum available number of rotations is 10, and the multipliers are 10x, 15x and 30x. As always, these "choose your volatility" options, the long-term victory should be the same. #5KOI #Play5KOINow #5KOISlot #5KOIAce333
