The Tournament part of the game offers great prizes for true Pac-Man fans like plush Pac-Man ghost toys. Can you name the ghosts in the game? They are Pinky, Inky, Blinky and Cyde. If you got it right, we're a little concerned about you. Anyway, in case you iOS users were getting a little green with envy, don't fear. There will be an iOS version of the app.
That does beg the question why Namco decided to go with Android first considering that for most developers it is the other way around. Namco explained the decision by noting that Android has the largest installed base today and that Pac-Man already has a presence in the Apple App Store. Namco thought that with this game it would be the perfect time for Pac-Man to make its debut on Android. And with the success of the freemium model, that is the direction that Namco wanted to go in.
"PAC-MAN has adapted to over 30 years of video game platforms and trends. Free-to-Play is the dominating model today, especially on Android, and we need to stay ahead of that. The Tournaments mode, where players can enjoy playing the classic PAC-MAN with never-before-seen mazes, is a perfect fit for this micro-transaction ecosystem."-Alex Adjadj, Director of Global Strategy, Namco Bandai Games America
