Found another one!

http://www.activehistory.co.uk/fling/quizzes/yr9_jack_ripper/quiz.htm - this one is online and it has been made by a group of year 9 students. It takes the format of 'who wants to be a millionaire' and so has 15 main facts from the case and if you answer all 15 correctly then you get to shoot your teacher out of cannon!

Something that i found interesting in the online game i mentioned in my previous post is that the gamemakers have incorporated other fictional crime-related characters in the game. As i progressed in the game, i had to fight a tag-team of Sherlock Holmes and Watson and then in level to i had to fight Jekyll as in Dr Jekyll and Mr Hyde. Jekyll managed to kill me.. Jack is dressed in the traditional cloak and hat that has now become his uniform.

There are card games that can be bought and also board games. Surprisingly, most of these things appear on American sites and are fairly recently manufactured.

Moving off the game topic, I came across this when I was searching 'Jack the Ripper games' in eBay:

The description was 'The London terror, Jack the Ripper immortalized in these throwing daggers. Stainless steel and a set of three.' Seems like a weird and painful game. They're going for about a fiver if anyone is interested, by the way!!
