A city map with a letter on the back and six numbered scratch cards – one per monster. Young Romans, Guild of Mind, A Wind in May and Prato Magico also come with stickers.

You only need a phone with internet at the end, to enter the code on wunderkammer.wien. No app, no GPS.

1. Read the letter, unfold the mapThe letter on the back of the map tells the story and explains the game. The map itself shows you where to go.
2. Head to the starting pointTake the first scratch card there – the cards are numbered. On the back of each card, a zoomed-in map shows the zone in more detail.
3. Scratch and solveScratch off the riddle – and only as many clues as you need. Where could the monster be hiding?
4. Found the monster?Scratch off the picture and compare. With the secret code on wunderkammer.wien you can read the monster's story and see its exact location – which is also the solution if you couldn't find it.

Yes. Every monster really exists somewhere in Vienna: a fountain figure, a sculpture, a stone face on a building – public art that most people walk past every day.

The legend: the Viennese forgot their monsters. Since then the monsters have been grumpy – and the grumpiness has spread across the whole city. Whoever rediscovers them sets Vienna free.

Every pack has a level bar from 1 to 6:

For ages 8 and up – 6–7-year-olds can play too. For the higher levels, it's best to puzzle it out together.

Whenever you like – outdoors and on foot, in the district your pack is set in. You don't have to find all six monsters in one day: take a break any time and carry on another day.

Only 1918 has restrictions: some of its monsters are inside public buildings with opening hours, so 1918 is best played Monday to Friday.

A gift you experience together: for families, for friends, for anyone new to Vienna – and for everyone who thinks they already know their city.
