A mysterious monster has been spotted in Utrecht, and the city needs monster hunters. This self-guided exploration game puts your family on its trail: follow clues from the Speelklok Museum past the Dom Tower, the Letters van Utrecht and hidden courtyards to the mighty Inktpot, and piece together where the creature hides.
