Under the Sea slots has a nice free spins bonus round, where you can win 15 free spins, with all wins doubled. As well as that bonus, there is also a treasure chest bonus too - with this one, you get a multiplier of your original bet. You won't win really big from these bonuses, but they are both fun to play.
The online version of the Under the Sea slot machine can be found in quite a few online casinos. However, if you want to play for real money, you can't yet do this if you live in the USA. Hopefully, that will come soon...
The Under the Sea slot machine is a really nice fish-themed game, that should appeal to fans of the Vegas classics, Mermaids and Goldfish.
The game has been well-produced to make it a lot of fun to play. A lot of attention to detail has really paid off and it's good to see it has symbols that can be easily separated from each other. So, when the reels start to fall into place you can tell if you are in for a big win or not.
