The aim of this game (apart from scoring points in various ways) was first to hit all 15 shields that were scattered around the school, and then to get the combination for the head teacher's safe and open it. Some shields you could hit just by jumping up to them, others required you to bounce bullets off teachers' heads. After you had hit all 15 shields, the teachers other than the history teacher would yell out a letter of the combination when you shot them. I heard that you could get the history teacher's letter by writing his date of birth on the blackboard, but never actually tried this.

Tip for getting points: when teachers are shot they always blame the nearest boy. Try to make sure this is the swot or bully.

There was a sequel called "Back to Skool" which introduced lots of new features including a girls' school, but I don't know much about it because my tape stopped working after only a couple of games.
