Rules are different from "normal" Baseball game, as follows:
1. Only one runner along bases. Runner advances according to type of hit (Single, Double, Triple, Home Run).
2. Rather than trying to hit ball as far as possible, you try to hit "targets" on the field which indicate how many bases the runner will advance. Runner advances past Home Plate to First Base, then Second Base, etc.
3. Runner scores One Point when landing on or passing Home Plate.
4. 3 Strikes = 1 Out. 3 Outs advances to next Inning. Game Over after Nine Innings.
I noticed a couple of occasional minor bugs, and you will too! 
 
 
Hope you will enjoy playing it! Let me know any problems or suggestions in the comments.  Thanks!
