GOzar is a (in development) software to practice the game of Go (Baduk), implemented in Clojurescript. It is hosted in gh-pages so you can try it here:
The name comes from the spanish word "gozar" which means "enjoy".
The first step is to upload an .sgf
(Smart Go Format). After that, the user
should try to guess where the stone was played in the loaded game. A bar will be
shown indicating how close (Taxicab distance) to the actual move the guess was,
this bar will turn green when the guess is really close (10% off, or better).
If the guess happens to be the correct move, then the stone will be placed
in the board. The user has also the option to skip a move and try the next one.
