Your first choice is to have 25 free games, each of which will see any victory using the Koi wild symbol multiplied by 2x, 3x or 5x. The other four options show that the number of free spins available is reduced, although the multiplier is increased. The minimum available number of rotations is 10, and the multipliers are 10x, 15x and 30x.
The first one saw you offer the opportunity to play only 6 free games, the multiplier here is the largest - 15 times. 30x or 40x. Another option might be the best choice because it is "mystery." Here you will get a random number of rotations and random multipliers, perfect for players who like gambling!
