There are 30 win lines as a default for this slot. You can select any number of these. Your stakes start from 2c per line (60c per spin) up to $1 per line for $30 per spin. The auto-play button brings up a box which lets you configure everything to your satisfaction before hitting the confirm button.

As with many BetSoft titles, the main wins come through combination wins and features – rather than from the regular line wins. The single biggest regular win comes from the blonde lady, which is worth 400 coins for 5 and 200 for 4. The green fish is next (300 coins for 5) and the yellow follows this one at 200 coins for 5. Next the blue, orange, grey and flatter blue fish prop up the prizes with smaller wins. There are no playing card symbols at all in this slot – which is always a sign of a solid design.

There are 3 special symbols. First the pearl - which is still in a clam shell. This is the wild symbol and has a handy multiplier attached. Wins with 1 wild are doubled, 2 wilds win 4x and 3 wilds create 8x wins. With all 30 lines in play, these wilds will often make multiple wins at the same time too.

The ship is the scatter; this triggers the free spins (8 for 3 ships, 12 for 4 and 15 for 5). There is a pay-out of 2x your total bet for 2 ships anywhere on the reels. The final special symbol is the treasure chest, 3 of these will lead to the pick-em treasure game.

There is nothing particularly interesting about the free spins round. When you hit 3+ ships, free spins are announced and the music track changes (becoming a little more calypso). You then simply run through your spins with the same set of reels as before. At the end of the game your winning total is shown, and you go back to the main game.

Treasure chests lead to a beautifully produced underwater scene, where you’ll get to choose from a number of chests with prizes attached. When you click they will open to reveal a prize in coins. You continue the game until you hit one which says ‘collect’, at which point the bonus ends.

These are not the most exciting or innovative bonus games compared to some BetSoft slots. Together with the wild symbols they do break up the game play very effectively.

Great graphics are the hallmark of this slot which will bring you on an underwater adventure, filled with thrills, spills and hopefully some big wins. It's not one of my favorite slots, but it's fun for a change and is a low volatility game. Best of all, it's at most online casinos that accept US players. Why not dive right in and take the plunge? You won't regret it.
