the same way as you would install any other component.
And as explained in
I'm happy to present version 3.0 of this great game.
It's almost completely rewritten from scratch and restructured in order
- to add compatibility with the sidebar menu of Ossn 4.x
- to get rid of the iframe to achieve a responsive feeling on smaller devices
- last not least some sounds have been added :)
Thanks again to Eric for the initial release and of course to Lucio PANEPINTO the originator.
