Loading the application:
* Mount the disk image (Compute 036 - One on One.d64) in your emulator. In VICE, this is done by selecting File → Attach Disk Image
* Load the app by typing LOAD”ONE ON ONE”,8,1
* Once loaded, type RUN to start


Game Instructions:
* One on One is a two player game that requires 2 joysticks or paddles. Player 1 is the joystick in port 1, and appears at the bottom of the screen; player 2 is in joystick port 2 and appears at the top.
* Each player controls a paddle by moving it left or right on the joystick. There is a ball bouncing on the board. To keep it moving, simply line up your paddle to hit the ball and it will be propelled towards the other player. If you miss, the ball will hit a block in your barrier, and it will disappear.
* Be careful, because the ball can hit your paddle on the way out and be bounced back into the barrier.
* When the ball breaks through a player’s barrier, they lose the game.


Article Text:
“One on One” is easy to learn, but not easy to master. Written originally for the Atari, it has been translated for VIC, 64, and Apple. The VIC and 64 versions include two skill levels and a suggestion for changing the object of the game.


—---------


In "One On One," two players go head to head in an attempt to knock down the wall their opponent is protecting.


The Atari version can be played with joysticks, plugged into control ports one and two, or with paddles, plugged into port number one. In the game, player one tries to protect the wall at the top of the screen, and player two defends the wall at the bottom.


The player's paddle (horizontal line closest to the middle section of the screen) is used to intercept the ball before it hits his wall and destroys a section. When the ball hits either player's paddle, it bounces toward the opponent's wall. On route, the flight of the ball may be changed or impeded by barriers or additional sections of wall which serve to make the game faster and more exciting.


Eventually, one or both players will lose enough wall so that the ball can go through it. The first player to get the ball past his opponent's wall wins the game and receives an appropriate victory message.


One On One is easy to learn and challenging. You'll keep coming back to play it again and again.


Editor’s Notes:
* The summary indicates that there are two skill levels for the C64 & VIC-20 versions, and a way to change the object of the game. These features are not in the C64 version of the game. An inset box appears with the Apple version and explicitly mentions that these features are included in that version, so my guess is that this is just a typo and they never meant to say that the features were included for the 64 and VIC.
* An inset box just above the C64 code provides optional code that will allow the players to use paddles instead of joysticks. This code was not implemented in this version.
* The game has been thoroughly proofed and debugged, but there are are a couple of significant issues with it:
   * The ball always bounces in the same direction, making the game significantly less challenging than advertised.
   * The player’s paddle moves all the way to the right, but cannot move all the way to the left; there is a space between the wall and the paddle that the ball can get through.
* Both of these problems should be easy enough to correct by someone familiar with C64 BASIC. My guess is that there wasn’t enough testing done for the port from the Atari version. There were no corrections for the game published in subsequent issues of COMPUTE! that I could find.
* This appears to be the only game development credit for Chris York.
