Timing and difficulty

Browser timers, rendering and touch input can vary by device. Reaction Test results are approximate and are not suitable for professional assessment. Computer opponents use simple game logic, not human-level expertise.

No prizes or wagering

Scores have no cash value. The site does not offer gambling, financial rewards or prize competitions.

Take breaks

If a game causes discomfort, stop playing. Use an appropriate display setting and avoid playing when it distracts from important tasks.
