Of course you must play with maximum bet to be able to win the progressive jackpot.
There are other strange/funny symbols, like a kind of weird looking seashore, octopus, oyster, sponge and sunken treasure chest from which three on an active pay-line can get you into a bonus round.
If you see three shark symbols on an active pay line you can try yourself against it in a card game.
All together this is a sweet video slot with strange cartoon-like symbols.
If you like this kind of sea life, you should give it a try.
You can play The Shark at Planet 7 Casino and enjoy their $7,777 welcome bonus package!
