A free arcade game built for the people fighting the world's deadliest infectious disease.
My wife works in TB. Every day she fights a disease that kills more people than any other single infectious agent on the planet — about 1.25 million people a year. Most of the world has no idea.
I built TB Eradicator as a tribute to her work and the global community of researchers, clinicians, and public health workers trying to end this disease. It launched in March 2026, timed to International Women's Day and World TB Day (March 24).
The idea was simple: take the classic arcade format everyone knows — defend your lungs against waves of bacteria — and fill it with real TB science. The four enemy types in the game are grounded in actual TB microbiology. If even one person plays this and walks away understanding that TB is still a massive global problem, it was worth building.
TB Eradicator is a free, non-commercial awareness project. There is no revenue model. No ads. No sponsors. No cookies or tracking software. All hosting and development costs are paid out of pocket by me through Madho LLC.
The site collects no personal data beyond optional leaderboard participation. It is designed to comply with GDPR and equivalent data privacy standards.
Donation links on the site go to established nonprofit organizations working in TB (currently Stop TB USA and Stop TB Partnership). I receive no referral fees, commissions, or financial benefit of any kind from those links.
If other game developers or organizations want to create similar tools for TB awareness, I welcome and encourage it. This project claims no exclusivity in this space. The more people building creative tools to fight TB, the better.
You play as lungs defending against four types of TB bacteria, each based on real microbiology:
Each type behaves differently in the game, just like they behave differently in real life.
Since launch, TB Eradicator has been played across 38+ countries and 200+ cities. Players from 9 WHO high-burden TB countries have found the game organically — including India, South Africa, Mozambique, the Philippines, Namibia, Eswatini, Ethiopia, Kenya, and Madagascar.
The game has reached global health hubs including Geneva (home of WHO and Stop TB Partnership), Atlanta (CDC), the Washington DC corridor (NIH, USAID), London (LSHTM), Cape Town, Delhi, Montreal (McGill International TB Centre), and Stockholm (ECDC).
None of that was paid distribution. People in the TB community found this and shared it with each other. That is the best possible validation.
