What it is about

You are A.D.A. - an Automated Deflection Agent - and it is your job to protect the server from hostile intrusions. You’ve detected a hacking attempt and must prevent the attacks, isolate the vulnerability, and identify a solution. A.D.A. is a solo dice placement puzzle which plays in about 10 minutes. Each turn you will roll a pool of dice, manipulating and placing them to defend against hacking attempts. Resolve each hack attempt before it bypasses your defenses or eventually enough security vulnerabilities will be exploited to compromise the server. A.D.A. is an entry into BoardGameGeek's 2026 9-Card Nanogame Print and Play Design Contest . All you need to play are 2 pages of printed components, some dice, and a handful of tokens of any type or color (although cubes work great).
