Just one other idea Mancala

The rules and a picture of the board are given here:
http://www.centralconnector.com/GAMES/mancala.html

If you are not familiar with the game, try it before you pooh-pooh it as too simple. The programming logic should be fairly straight forward, but still challenging and the player needs to play a clever strategy. It is more complex and unique than tic tac toe.

Advantages as a Science fair project – it can be designed and developed in stages, any of the stages would be acceptable as a project for the fair submission.

Possible steps:

1)board lay out can be in non graphic mode, using digits to represent the number of stones in each bowl. With dashes or * as separators.

2) programming can be done as a series of variables, or as an array to calculate the move results handled in either for, or while loops.

3) user input can be designated as a text entry designating the bowl whose stones should be distributed.

4) the gui representation can be added later if time permits.

Good luck to your sister in the project!

And I bet you could point her to a super place to get perl advice!

Update - here is some crude code - it uses arrays and simple control statements to create a text mancala board, allows a user to enter a bin number and then distributes the stones. Please note there are much more elegant ways to handle the situation, but I tried to keep the code concepts fairly basic so a new user could get a feel for it wihout being overwhelmed. I assume you will be helping/coaching your sister.

I would strongly suggest you and your sister play the game in the real world, to get a feel for where the code should go.

this code was developed in the following order:

1) create 2 arrays, display the board.

2) accept user input, and edit check it.

3) distribute stones code

#### don't panic this code is not complex, just repetitive

Nuff said, I hope this code may help as an idea generator.
