This is a logic / puzzle game. A grid is displayed on screen, and a smaller version in the corner shows the pattern you have to complete. You nip about the grid in the usual fashion, and when you press fire, as if by magic a little coloured number appears. The nasty bits start when you put two numbers adjacent to each other - horizontally or vertically, but not diagonally. When you do this, the number already on the board increases by one. If it's a number four, it flips back to a one.
