Similar to the classic Atari Football arcade game, X and O Football is a very simplified version of football where the players are X's or O's.
In X AND O you play either as the offense or on the Windows platform the defense (in a 2 controller game) and choose 1 of 5 plays to try to score touchdowns and field goals or make 1st downs. Plays to choose from are (1) slant-out, (2) slant-in, (3) bomb, (4) down and out or (5) kick/run/blitz. A 20 second play clock keeps the game pace moving and each game has a 15 minute time limit. Offensive scores can range from 3 points for a field goal, 6 points for a passing touchdown or 7 points for a rushing touchdown. The defense can score on a 2 point safety if the quarterback is sacked in the end-zone and can also intercept passes.
I like this game a lot
Although the instructions say you need a gamepad, I was able to use the keyboard without a problem.
Numbers keys to pick a play
Arrow keys to control the player
Move the receiver into the highlight to make a catch
