SCRAMB is a deceptively simple tile-based puzzle.
You are presented with a square grid of 9 tiles and all you need to do is rearrange them back into the correct order. To move the tiles around, just click on them to move them to the top area. When the top area is full, the tiles will automatically drop back into the main grid. That's all there is to it.
Well, perhaps it's a little trickier than that.
