Dolphin Quest

If you miss the old computer screensaver of a personal aquarium, you're going to love Dolphin Quest. This slot machine online game from Microgaming takes place in an undersea world teeming with beautifully designed creatures that deliver big wins – including a 150,000-coin jackpot.

The game has five reels and four rows in a floating grid – literally floating in the ocean, surrounded by coral and other sea flora. There are 50 pay lines. The minimum bet is .01 credits per spin. The maximum is 250 credits per spin. You can determine coin value, bet lines, and autoplay parameters by using the player dashboard. It's nicely tucked into the bottom of the screen, and not too distracting.

Icons include a group of four dolphins, plus fish, sea turtles, sea horses, hermit crabs, octopi, and stingrays. Each is designed so well, we found ourselves pausing a few times between spins to take a closer look at them. It's simply a gorgeous game, win or lose.

The Dolphin Quest game logo is your wild card. It can substitute for anything you need to make a win. And, they are stacked, which can result in more wins. Meanwhile, Golden Dolphins are the scatter icon and can send you to the bonus game, which takes place on another screen.

Here, you will see a three-reel slot machine where you have free spins and the chance to win big money by stopping the reels yourself using a giant STOP button. But to trigger the bonus, you'll need the golden dolphin scatters on the second, third, or fourth reels (albeit anywhere on those reels).
