Here is one of the maze puzzle games in my opinion on the 8 bit series. This game sharpens your mind and makes you think by plotting how you want to attack the board.
In this game your objective is to cut off 75% of the board away and trapping the scrolling object in the remaining portion. Each % over 75% you receive a 1,000 point bonus. In the later rounds with 2 objects floating around if you can split them in the first pass all cuts you make and bonuses you get from the extra amount over 75% will be doubled.
