Created on April 16, 2006, Dan-Ball.jp is the main website for the Web games developed by ha55ii, such as Powder Game and Stick Ranger. These games were first created to run with Java and later with HTML5 as Java support was dropped by certain browsers. It also features some optical illusions made with Flash. The site is primarily run by ha55ii, and one game that he programs is usually updated every Friday. The site is available in two languages: Japanese and English. The site was also available in Chinese until February 2017. Dan-Ball can also be "tweeted" on Twitter and "liked" on Facebook.
