Common Questions
Can I embed your games on my site? — The iframe games come from famobi.com and other platforms. Please check their terms directly. The reaction time test code is open source (MIT) on GitHub — you're welcome to use it.
Can you add a specific game? — Tell me which one! I prioritize games that are free, embeddable, and work well on mobile.
My score seems high/low. Is the test accurate? — Device latency (touchscreen vs mouse, browser, system load) can add 20-50ms variance. For the most consistent results, use a desktop browser with a mouse, close other tabs, and take 3-5 sets of trials.
I typically reply within 24-48 hours.
