Wythoff's Nim II

This is a second and a more direct implementation of Wythoff's Nim. To remind, the players take turns removing any number of objects from one of the heaps, or removing the same number of objects from the two heaps simultaneously.

In the applet objects are removed from the right. Click on the last square you want removed. If the box "Two heaps" is checked, the same number of objects will be removed from both heaps regardless of which one you click upon.

<hr> <h3> This applet requires Sun's Java VM 2 which your browser may perceive as a popup. Which it is not. If you want to see the applet work, visit Sun's website at, download and install Java VM and enjoy the applet. </h3> <hr>
