When Apple introduced the iPod MP3 player, it discovered additional uses for its LCD display, such as gaming. The company developed its own version of Tetris called “Stacker” to release alongside the 3rd-generation iPod in 2003, but the plan was never realized. Tetris eventually became officially available on the iPod, making the in-house clone unnecessary. However, the YouTube channel “Apple Demo” managed to retrieve a version of Stacker, showcasing it on a prototype model of the 3rd-gen iPod from 2003. The video demonstrates the basic nature of this version of Tetris, along with other games like Block0, Chopper, and Klondike also present on the prototype device. Apple Demo may cover these games in the future as well.
