This version of Gomoku was written a few years ago when I was in college. I decided to port it to Windows after seeing the Gomoku2 program in the CICA archive. Here is a feature summary: 1. It is much easier on your eyes. The appearance is closer to the real thing. The board grows/shrinks with the window so it's especially nice on a big monitor. 2. There is unlimited undo/redo. So cheat all you want. 3. You can save games and resume play later. 4. You can play with the computer or with a friend. 5. The algorithm is based on a set of heuristic rules. It is not as (overly) aggressive as the Gomoku2 program. By being defensive for the first few moves and keep your eyes in focus, I found that you could beat Gomoku2 almost every time. Not that my algorithm is any better. I beat my program most of the time too. But the source code is available if you think you could do better. The intelligence part is totally isolated from UI. Just drop me an email. 6. The program is fairly small. Just the executable file and no extra DLLs. There is no help files either though. 7. Last but not the least, the program is totally free. You are free to do whatever you want with it. 8. The program was done in VC++ 2.0 and then targeted for 16-bit Windows. Please email bug reports and/or comments to dxu@netcom.com. Enjoy.
