I'm currently creating a darts scoreboard, and was looking to implement a 1 player v computer game where the computers scores generate random numbers between 0-180. Ideally I'd have 3 or 4 levels where on the hardest level the numbers generated were higher than the ones on the lowest level.

I'm sure there'd be a way to do this, but wouldn't really know where to start.

The further additional problem I have is when it gets close to finishing the game. On the hardest levels, the computer would finish the game (i.e. get to zero) a lot quicker than on the lower levels (where the computer might get down to a low number but take 2 or 3 attempts to get to zero)

Does anyone have any ideas on how to implement this, or if it is even possible in excel?

Thanks in advance
