From features there are the free spins and the win-win feature. To reach the free spins you need to have at least 3 symbols with the ships. For 3 of these symbols you will get 8, for 4 -15 and for 5 you will receive 50 free spins. The symbol with the Moby Duck is a wild symbol. For the duration of the free spins, every time when this symbol appears on the first or the fifth reels then all the symbols on the screen with the ship, the captain and the harpooner are transforming into wild symbols. This of course allows you more chances to have a bigger wins.
The WIN-WIN feature I have already described it in some reviews about the Real Time Gaming games. Here I will write only that in case if you do not have any wins in the free spins you get 250 x bet.
When I came here my balance was at a solid 100 + Dollars. From a precaution, because for the first time I met with this game, I started with a minimum bet per spin of $ 0.25. Soon, I got the free spins bonus. There was not much of a decent wins in those free spins but I figured it out that soon I could come again to free spins, so I have increased the bet at $ 0.75 per spin. But my sense has cheated me and the assessment was wrong. Soon my balance fell below 50 dollars. So, the Moby Duck is one more NuWorks game where I’m in minus. No matter that, I will give for this game 7/10.
