X Marks NJ is a real-world treasure hunt experience created by New Jersey educator and author Gregory-John. Designed to bring adventure, curiosity, and exploration back into everyday life, X Marks NJ invites participants to follow a series of clues that lead to meaningful places across the Garden State.

The hunt unfolds over five weeks, with each clue guiding players to public locations tied to New Jersey’s history, geology, and culture. Participants must visit these places, observe their surroundings, and gather pieces of information that ultimately unlock a final clue revealing the location of a hidden treasure chest.

Created with families, explorers, and puzzle-lovers in mind, X Marks NJ is family-friendly, and accessible, encouraging people to get outside, learn something new, and experience the thrill of discovery.

The hunt blends storytelling, puzzle solving, and real-world exploration—turning the entire state into a living map.

The winning team that solves the final clue and finds the treasure receives a $500 prize and a commemorative coin, but the true reward is the adventure itself.

With a passion for storytelling and discovery, Gregory-John created X Marks NJ to inspire people to explore more, think deeper, and rediscover the excitement of the hunt.
