Pac-Man: Championship Edition is a sequel, by the same developer Tōru Iwatani, done in the style of the original classic. As before, you are Pac-Man and you are in a maze with dots, power pellets and hosts. The object is to eat the dots and avoid the ghosts, unless you eat a power pellet, which gives you the ability to eat the ghosts for a few seconds.
What's new here is many different mazes and modes. This is designed from the ground up as a console game, so some arcade traditions are lost. The object is no longer to try to survive/get a high score without losing quarters, but to get a high score in a set time limit. You do still have a set number of lives, which makes your time end early if you lose all them.
Unlike the original or its prodigy, Championship Edition isn't broken into distinct levels. Once you clear one side of the maze, a fruit appears on the other side. Eating the fruit regenerates the empty half with new walls, dots, power pellets, etc and increases the game speed.
The iPhone version of the game adds two additional modes. In "Mission Mode", you must clear a specific goal set by the game at the beginning of play (such as eating two apples, or eating eight ghosts consecutively). In "Challenge Mode", you must aim to achieve the top score for each course, but this time the ghosts have been sped up so that they are initially much faster.
The look is a bright neon which evokes the classic Pac-Man but takes advantage of nearly 30 years of increased computer power.
