Houston's Little Detectives: Solve the Case!

Someone stole the Sensi-Stone — the source of all sight, sound, smell, taste, and touch! The sky has lost its color, the birds no longer sing, and even the bakery doesn’t smell like fresh cakes.

You play as a very clever detective and, together with your friends and family, you must track down the missing stone and return it to its rightful place in the city square.

Can you find it and bring all the senses back before it's too late?

• Interactive clues & mini-games that teach sight, sound, taste, smell and touch
• A 60- to 90-minute self-paced route in the heart of the city
• Team play – kids recruit parents, siblings or friends to solve puzzles together
• Digital “Sense Badges” and a printable hero certificate at the finish line

• Built with experts
  The game was co-created with a licensed therapist to ensure age-appropriate challenges that nurture sensory processing and social skills.
• Used by teachers in kindergartens and primary schools as a hands-on learning activity that meets early-years curriculum goals.
  

• Combines outdoor fun with hands-on learning
• Designed specifically for ages 4–8, with adult guidance built in
• Screen-light: phone only for the Questo app—everything else is real-world exploration
  

• One ticket unlocks the quest on one device (up to 4 kids can share).

• Children must be accompanied by an adult guardian.

• Start any time between 10 am and 6 pm.
