Brains, The Game

In my book, Testing with F#, I work out an example on model-based testing using a game called Brains.

I first met this game on the Amiga when I was growing up, facinated by its simplicity and genious. The rules goes like this

• Recreate the grid on the right to the left
• Click the grid to place out 1's
• Each 1 you place will increase the value of neighbours
• If a cell is increased from 4, it will turn-around and become 1

Here's the game. (you need to read this in a javascript enabled browser)

Play Brains!

The Code

Since this is a programming blog it wouldn't do unless I posted the code for the game also.
