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.
Game Search is a tool on the website that is used to search for games that are not on the Dan-Ball site itself. For additional features included within the games, it requires the user to sign up for an account. However, it is still possible to play games without one.
Irritation Stickman (en/jp/cn) - A game in which the player drags a stick figure (similar to fighters in Powder Game and characters in Stick Ranger) around levels. The amount of time a stick figure can be dragged is timed.
In response to Google Chrome's dropping its support of Java in 2015, every week during the time period of May 15 and October 23 of the same year, a game was either recreated in HTML5 alongside the Java version, or it optimized the existing HTML5 version of a game. The following is a list of all web games and their corresponding HTML5 creation/optimization dates:
|Web game||HTML5 date|
|Powder Game 2||21/08/2015|
|Powder Game 2*||28/08/2015|
|Ham Race 2||11/09/2015|
|Ray Trace Fighter||25/09/2015|
**Optimization update after the end of the HTML5 period
Dan-Ball's color illusions use the effect of an negative afterimage or ghost image to colorize a normal black and white image.
In Looking for mistakes, the player has to find the difference between two images called A and B. The game either flips between the two images with a small break in-between, or it blends very slowly from one image to the other and back.
Dan-Ball also features games made for mobile systems, wallpapers for iOS and Android systems and BGMs for the mobile games.
There are currently 21 mobile games available as downloadable apps.

Mobile Web Games
There are currently 3 mobile web games available for the internet browsers in mobile systems. These can only be played in a mobile device, unless the browser's User Agent String is changed. However, since 16 November, 2012, PC support is added to these games, and can be played in some internet browsers for computers without changing the internet browser's User Agent String.
