XBill

The Open Source game XBill is a "hit the mole" type game which the character known as "Bill", wearing large eyeglasses, is trying to install Windows on computers running other operating systems.

The operating systems are represented by their logos shown on the computer screen. Some of the operating systems include Linux, SunOS, Mac OS X, FreeBSD and NeXT OS. When "Bill" installs Windows onto a computer, its old operating system is placed beside it.

Using your mouse, you can both slap "Bill" and drag the old operating systems back to the computers. At the end of the level, you get points for every computer that is running any other operating system than Windows.

On later levels, computers are connected to each other with LAN cables, causing Windows to spread faster. Some computers may also catch fire. This can be cured by dragging buckets of water onto them.
