This self-guided walking tour game starts in Solgränd in Stockholm's Old Town. Open the mobile app and start the Ghosts and Ghouls of Old Town tour here. Gideon the ghost will greet you and invite you to walk around with him, as he completes his tasks as a caretaker for the dead.

Gideon takes you to Stortorget square, where the Stockholm Bloodbath took place in 1520. He shares the story of what happened during those fateful days when nearly 100 people lost their heads here.

You continue to Kindstugatan, and the former location of the Fimmelstången tavern, where a famous bard was killed in the 17:th century. Gideon requires your help to operate a radio playing one of the bard's lovely tunes.

You follow Gideon to Själagården, a former lodging house for the old, poor and sick. The ghosts at Själagården are upset, because humans have tried to expel them by hammering iron nails into the doorframe. Maybe you can help Gideon to calm the restless spirits?

It's time to join Gideon for a visit to the Royal Palace and its noble ghosts. When you get there, the White Lady meets you outside and pleads for your help with an unpleasant task.

You make a stop at a former execution site at Norrbro, where King Magnus Ladulås was executed in the 1200's. Gideon thinks he can hear a ghost calling for help, and asks for your assistance.

Suddenly you hear fiddle music coming from the water, and Gideon becomes upset. It's his nemesis, the folklore creature Näcken, who is trying to lure unsuspecting tourists into the water. Gideon asks for your help to make Näcken go away.

Gideon takes you to the most notorious ghost location in Old Town: Hell's alley. This is where the former city executioners reside in life after death. You need to be careful and don't let them trick you.

Finally, you reach the Riddarholmen church and Gideon's home. It seems like Gideon has saved one final surprise for you here...
