Uncovering Potential Security Flaw in Dave & Buster’s “Find the Flag” Reno Promo

Today, I want to bring attention to an important issue regarding the ongoing “Find the Flag” promotion hosted by Dave & Buster’s in Reno.

During my participation, I was alerted by another user to a concerning loophole that could potentially undermine the fairness of this game. It appears that the clues for the activity are hosted publicly, with predictable URL patterns tied to specific dates. By utilizing basic browser developer tools, anyone with minimal technical knowledge can access future clues ahead of schedule.

Here’s how the exploit works:

• Opening the webpage using developer tools
• Inspecting or viewing the source files related to the clues
• Modifying the URL to reflect upcoming dates (e.g., changing clue-2025-07-16.jpg to clue-2025-07-17.jpg)
• Instantly revealing the next day’s clue

This process relies on the fact that the clues are stored openly without server-side controls or access restrictions, making it straightforward for users to bypass intended game mechanics. As a result, some participants managed to find multiple flags within minutes of their release, significantly faster than those relying on traditional deduction methods.

In response, I have reported this vulnerability directly to Dave & Buster’s Guest Relations, providing detailed screenshots and technical insights. I believe transparency and prompt action are essential to preserve the integrity of the game and ensure all participants enjoy a fair experience.

While I remain cautious about jumping to conclusions regarding intentionality — whether this was a careless oversight or an inside advantage — I hope the company will investigate and address this loophole promptly.

Please note, I’m sharing this information not to shame but to promote awareness and encourage responsible handling of such issues in digital promotions.

Stay vigilant and always approach online giveaways and promotions with a critical eye.
