If you have purchased a license to the full version of Algodoo, you will have to unlock the demo to use it. Just follow these simple instructions:

• Start Algodoo
  • If you are running Linux, then run the application as administrator (i.e. "sudo ./algodoo").
• Find the "File" menu (top left corner) and click it
• Click the "Unlock Algodoo..." button (the button with the padlock)
• Enter the name and e-mail, as well as the serial key you were given upon your purchase. These can all be found in your e-mail receipt.
• Click "OK".
  • At this point you may get a dialog asking you to log in as administrator. Either enter this information yourself, or, if you are not the owner of the computer, find an administrator to do it for you.
• Enjoy the full version of Algodoo!

A new beta version is also available for public testing. Further information is posted in our user forums.

For nostalgic reasons we still make a beta version of Algodoo available (called "Phun Edition" or often just "Phun"). Note: This version is not actively supported and the license explicitly prohibits commercial use as well as pre-installation or bundling with hardware and other means of volume installation of the software. It is intended for personal use only. Algodoo offers many more features, including lasers and optics, graph plotting, vector visualization, incompressible water, skins, themes, a multi-sketch tool, support for interactive boards, and much more.
