The X & O has long history.
The first version of X & O for MS-DOS was created in March 1993. This version had limited number of games and had a lot of problems.
Sun Microsystem created a new computer language Java. I decided that it is perfect language for my project , converted codes from C++ to Java and created Java version of X & O. This version is available
In 2000 I got my first PALM. I was fascinated by this device and started develop applications for PALM OS. I wanted move X & O to PALM. To do this I changed language again: from Java to C++ and created many applications to play board games for PALM OS:
Testing games on PALM is slow process. Therefore I created a MS Windows program to run games, adjust evaluation attributes e.t.c. I added more and more feature and after some time of creating and testing games for PALM OS the X & O for Windows was made.
