I'm creating Jex because I'm kinda angry that there is no Qix on the 2600. To start the game, press the title screen. You can only move in straight lines in this game. The red number is the percentage of the board you've cleared. The idea of the game is to get the red number up to at least 85 to clear the level. To make a line, simply move the cursor into the white territory without hitting the Jex, the ball-like thing(s) bouncing around the screen. The number of lives remaining is the squares to the left of the board.
