The object of the game is to shoot bibles at heathens and convert them to Christianity. The player has 10 shots to turn heathens into Christians. 125 points are awarded for a successful shot, and 25 points are deducted after a miss. A partial conversion will make the heathen a Unitarian.
Behind the laughter
- It is based on the unlicensed NES game Spiritual Warfare, where, like Billy Graham's Bible Blaster, the player is encouraged to "convert the heathens" by shooting them.
- On the official Simpsons website, it is featured as a minigame on Rod's character biography.
