Interactive detective game CluedUpp has taken over Australia's streets before — and if you like the idea of true crime and Cluedo colliding while you run around town, then it's the pastime for you.

Its next Melbourne event on Saturday, July 31 will bring the classic board game to life throughout the city once again, with a slight twist. The outdoor adventure will have you tracking a Jack the Ripper copycat — and while the serial killer was very real, everything else about this murder-mystery game will be fictional.

Forget Colonel Mustard with the candlestick in the study — this event will bring you and your friends closer to reality and out onto the streets to solve the case. The game will kick off at a secret location, and you can choose to start whenever you like between 9am–2pm. Then, how long it takes depends on how good of a detective you are.

The best news of all, however, is that the event is dog friendly — and there are prizes to be won by both human and canine detectives.

All you need to play is some friends and your phone. Dressing up as a detective is encouraged, so you can really get yourself into character. A ticket will set you back $65 per team of six, but you only need two humans to play. With only 100 teams available, get in quick for your chance to solve the mystery.
