The "Easy Joe" game has been removed from Apple's App Store for the iPhone as of 2015. However, it may be possible to play Flash versions of the game by using a Flash-enabled iOS browser.
Several websites have versions of "Easy Joe" that run in a Web browser using Adobe's Flash technology. However, Apple does not support Flash in the Safari Web browser installed as standard on iPhones. Other software makers do make Flash-compatible browsers for the iPhone, such as the Puffin browser produced by CloudMosa, that can run these versions of "Easy Joe" on the iPhone. Performance may vary depending on the specific model of iPhone used.
