If Eric is caught out of class or otherwise misbehaving, teacher characters pursue him and issue lines. When 10,000 lines or more are accumulated, the game ends with Eric's expulsion. However, Eric can also receive lines for things that are not his fault, such as lying or sitting on the floor when in fact he has been knocked down, or being nearest a teacher who has just been hit by a projectile fired by one of the other pupils. So part of the challenge of the game is to prevent other pupils from getting Eric into trouble.
