14-Jan-09 NEW GAME: 4 In a Row
This game can keep you occupied for hours.
I wrote it in an afternoon, and tested it fairly successfully on the baby sitter so I think it works OK.
There are 6 levels of difficulty from 1 (really very stupid indeed) to 6 (if you're not careful, you could lose)
I would consider programming in more levels if the demand is there.
It's Open source, so click ALT + F11 to look at the VBA code. This is a great example of what you can do in a simple Excel Spreadsheet.
