Atlantis is an underwater-themed puzzle game in which different types of fish spit colored balls that stick together and disappear if you link together more than three of the same color. It may sound odd, but you've probably seen plenty of puzzle games like this before.
There is a story to Atlantis, which involves a poor puffer fish who has to free her husband from the evil Poseidon. It really doesn't matter, though, because you don't play a puzzle game for the plot. What does matter is that the gameplay is fun and addictive. You rotate your fish around the center of the screen, shooting balls that stick to a central cluster. If you string together three balls of the same color, they disappear. The object is to clear all the balls on the screen, but that isn't always easy--enemy fish will come in and spit their own colored balls to mess you up. Fortunately, there are 15 power-ups you can collect to make life a bit easier for your little fish. So if you like puzzles and you happen to be fond of brightly colored fish, this game will keep you entertained with 50 levels of simple but fun puzzle action.
