FAQ

Are these brain games free?

Yes. Every test is free, needs no signup and runs entirely in your browser. Your best scores are stored only on your own device.

Do brain games make you smarter?

These tests measure a specific skill such as reaction speed or short-term memory on the day you play. They are fun to compare and track over time, but they are not a medical or intelligence test.

How often should I retake a test?

Scores vary with sleep, focus and device. Play a few rounds and compare your best result, rather than judging from a single run.
