How the daily challenge works
Complete five valid reaction responses, recall three sequences, and identify ink colors for 30 seconds. Each result is shown separately; CognitiveBench does not combine them into an unvalidated brain score.
A new challenge begins at 00:00 UTC. The daily reset uses UTC and your device clock. Your progress is saved on this device when browser storage is available. The sequence and color order are generated from the date and challenge version; reaction waiting times stay random. Different devices, input methods, and answering speeds affect results, so this is not a strictly fair competition.
Your first completed run is saved as today’s result. Practice runs do not change your daily record. Clearing site data, changing browser or device, or storage failure can remove local history.
Frequently Asked Questions
When does the daily challenge reset?
A new challenge begins at 00:00 UTC. The date uses UTC and your device clock, so changing the clock can change which challenge appears.
Does everyone get the same challenge?
For the same UTC date and challenge version, sequence patterns and the color-trial order are generated consistently. Reaction-time waiting periods remain random, and faster players may see more color trials.
Are my results saved?
Your first complete daily run and up to 90 recent daily records are saved in this browser when local storage is available. Clearing browser data or changing browsers or devices can remove them.
Can I play again?
Yes. After finishing, you can practice again. Practice results are labeled and do not replace the first completed daily record or increase your streak.
Is this a medical or IQ test?
No. It is for entertainment and general self-comparison, not an IQ score, diagnosis, or clinical assessment.
Why can results vary between devices?
Screen refresh rate, browser timing, input latency, device performance, color display, and your answering speed can all affect results. This is not a strictly fair competitive test.
