Scratch So, we looked last week at Scratch, very briefly, but hopefully you found if you've dived in already that the interface is fairly intuitive and it really just allows you to implement ideas that you conjure up in your mind.

So, not surprisingly in this game, it turns out that if the goalie dived to the left you're best off shooting to the right, second best off shooting to the middle, and worst off shooting to the left.
