3-D_Brickaway (renamed Breakthru (an early catalog screenshot shows "3-D Racquetball") when it was re-released by Avalon Hill in January 1983) is a 3 dimensional version of Breakout. Viewing down a square tunnel, with your paddle nearest you, and the bricks at the far end of the tunnel, you must bounce the ball and take out all of the bricks at the end, using your joystick. It's author, Britt Monk sold it himself in late 1982, and then ended up selling it through Avalon Hill just a few months later. Later still, he ended up porting the game to the Commodore-64 which also was sold by Avalon Hill in 1984.
Easter Egg: If you look closely at the ball when it is nearest your paddle and you don't hit it, it will say 'Oops!'. Just before this point (whether you hit it successfully or not), it will say different words as it gets closer to you: 'It', 'is', 'fun' and '!'.
