The crown is the wild symbol and it will substitute for all of the other symbols to help and form winning combinations.
There is no scatter symbol.
Ocean Princess does not have any bonus features but it does have a Hold feature. When you spin the reels initially only the first row spins. You are then able to hold as many of the reels as you wish and the symbols on it will be replicated across the other four rows. Thanks to this, if you land a winning combination you can hold it across all five rows and be sure of a large payout.
Ocean Princess has a top payout of 1000x for landing three wild symbols when betting the max, when betting less than the max it will payout 250x. The red, orange and green starfish can payout 125x, 100x and 75x respectively while a mixture of any three will payout 25x. The red, orange and green crabs will payout 50x, 35x, and 20x respectively while a mixture of any three will payout 10x. A mixture of any three starfish and crabs pays out 5x. The red seahorse can payout 30x, and the yellow seahorse can payout 20x.
