Ponx

This is the game Pong brought to the Atari Lynx, but with added options. You
can control the difficulty, field color and number of balls in play. You can
play one player or two players using one Lynx and Ponx cart, no Comlynx cable
needed. If you select two players, the control pad is used to control the left
paddle and the A and B buttons control the right paddle.

The game play is the typical Pong game. Simply prevent the ball (or balls)
from getting past your paddle while trying to get the ball (or balls) past the
opposing player’s paddle to reach the winning score.
