The Lucky Koi video slot is a 5 reel slot machine with a Chinese garden theme. The slot has wild- and scatter-symbols. When you hit three scatter symbols on the screen you will get a bonus: you can choose between free spins and the koi bonus game.
If you choose for the free spins you will also receive a random multiplier. In the koi bonus game you have to fish a couple of koi fishes out of the pond, and every koi will give you a random amount of coins.
