In this category I used to keep my browser games which I had developed ages ago in Java. Since they were running as Java Applets in the browser, I have removed them.
Maybe some day I'll re-implement one of those games with more "modern" technologies like HTML5, Javascript and maybe even WebGL.
For reference here is a list of the old games. Most of them had online highscore lists.

Wejp's Monkey Planet is a small oldschool space shooting game. Your task is to shoot the yellow space ships and finally to destroy the monkey planet! Once again, I have programmed this game using Java.

Miniball SE 2 is a game which is similar to breakout but in this game the ball has to be caught with four pads instead of one. I have programmed this game in December 2001 using Java 2 (SDK 1.3.1). Now this game has a highscore list!

Double Wejptris is a Tetris game for up to two players! In the one-player-mode it has a highscore list! It is a java game which will be loaded from your web browser! I have programmed this game in April 2001 using Java 2 (SDK 1.3).

Brain Game is a Mastermind game for your computer. As I have programmed this one in Java it will run on any computer with a java compatible browser. If you don't know the rules of this game you will find them on the game's page. I have programmed this game in September 2000 using Java (JDK1.2).

In this game your task is to move all four frogs from the left side to the right side and to move the other frogs to the left side! Try to make as few moves as possible! I have programmed this game in September 2000 using Java (JDK1.2).

Java Avenger is my version of the old Commodore game "Avenger". You will need a browser that is able to run java applets. I have programmed this game in January 2000 using Java (JDK 1.1.8). The game will be loaded in a new browser window. Now this game has a highscore list!
