Namco Bandai released the official Android version of Pac-Man in March. Pac-Man + Tournaments, as it's called, allows you to play the classic version of Pac-Man that we all know and love, but also adds a tournament mode with new mazes.
In its most recent update, Namco Bandai added a new Android twist to the tournament mode by allowing you to chase and chomp on Androids, instead of the usual ghosts (Blinky, Pinky, Inky, and Clyde). The Androids will only be available through the end of August, however, so you'd better hurry if you want to play.
To play with Androids, tap on "Play Tournament," otherwise, select "Play Pac-Man" to start the classic version. The update also added SD card support, so if you have a phone with a microSD card slot, like the Samsung Galaxy S4, you can move the game to your SD card.
