The experience

About this quest

Follow Victor Kral’s unfinished investigation through Prague and uncover the mystery of the Thirteenth Sign. His manuscripts lead you through the Old Town, where clocks, statues, Hebrew symbols, medieval towers and old house signs hide pieces of a larger pattern.

Observe real details around you, solve Victor’s puzzles and discover what he failed to understand in 1681: what — or who — is the Thirteenth Sign?

About 2 hours. 2.5 km, all on foot, all outdoors.

Is this for you?

Who it's for

Puzzle and escape room fans, and families with older children, spend about two hours in Prague's Old Town reading clocks, statues, Hebrew symbols, medieval towers and old house signs to finish Victor Kral's investigation, left unsolved in 1681. The medium-difficulty puzzles depend on spotting real details around you. Anyone hoping for a live guide to answer questions, or who cannot walk 2.3 km outdoors, should choose something else.

Frequently asked questions

What is the Thirteenth Sign quest about?
It is a self-guided mystery in Prague's Old Town. You follow the manuscripts of Victor Kral, whose investigation stopped in 1681, and solve his puzzles using clocks, statues, Hebrew symbols, towers and old house signs. The goal is to work out what, or who, the Thirteenth Sign is.
Where does the quest start and finish?
It starts at the stop called Death Knows the Time and finishes at The Gate Has Two Faces, so it does not end where it began. In between, you pass Read the Heavens, The King in Stone, Five Stars, The Clock That Reads Differently, Between Two Windows and The Road of Kings.
How long does it take and how far is the walk?
Most players take about 1 hour 45 minutes, including walking and puzzles. The route covers about 2.3 km, all on foot and all outdoors, so dress for the weather. You can pause at any point and continue later.
Is it suitable for children?
It is a family favourite best suited to older children, roughly 10 and up, who enjoy mysteries. The puzzles are medium difficulty and ask players to observe real details around them, so younger children may need a lot of help from adults.
Is it free, and do we need to book a time?
It is free to play. There is no group to join and no guide to meet, so you do not need to book a slot. Start whenever you like on your phone, play together as friends or family, and pause whenever you need a break.
