    paper Backyard Hunt - QR Code based Treasure / Scavenger Hunts for Kids

    Backyard Hunt is an engaging mobile app designed for all ages that combines the excitement of treasure hunts and scavenger hunts with the convenience of modern technology. It provides a versatile platform where users can embark on adventures either individually or with friends and family, making it perfect for outdoor fun, educational activities, or creative challenges.

    https://www.twine.net/signin

    Key Features:

    1.	Treasure Hunts: These hunts are structured with sequential clues leading to a final reward or surprise. Participants must solve each clue to progress to the next one, ultimately discovering the treasure at the end. The app allows users to create their own treasure hunts, providing a customizable experience that can be tailored to any environment.
    2.	Scavenger Hunts: These are more flexible and non-linear compared to treasure hunts. Participants can find and solve clues in any order, making them suitable for larger groups or less structured play. The goal is to discover all the clues without needing to follow a specific sequence.
    3.	QR Code Integration: The app utilizes QR codes to reveal tasks, clues, and hints. When a player scans a QR code, it reveals the next task or clue, enhancing the interactive experience. QR codes can be easily placed around a backyard, park, or any suitable location, allowing for endless possibilities in hunt design.
    4.	Customizable Hunts: Users can design their own hunts, choosing from a variety of thematic tasks and clues. The app offers preset content to streamline the creation process, but users can also create fully personalized hunts, complete with custom questions and answers.
    5.	Modules for All Ages: The app includes different modules catering to various age groups. For toddlers and preschoolers, the tasks are based on pictures and sounds, eliminating the need for reading. Older children and adults can enjoy more complex and educational hunts, making Backyard Hunt suitable for everyone in the family.
    6.	Shared Private Hunts: This feature allows users to share their custom hunts with friends and family via a link or QR code, making it easy to spread the fun without everyone needing to subscribe to the premium version.
    7.	Subscription Model: While the app is free to download and offers a basic hunt module for trial, users can subscribe for additional features, including access to more hunt modules and the ability to customize and share hunts. The subscription can be monthly or yearly, with ongoing updates and new content.
