Cognitive Gym publishes six free browser exercises: counter-sequencing, colour against word, a Schulte table, Go / No-Go, spatial sequence and rule switching. No account or subscription is required. The site states that completed rounds, time and game metrics remain only in browser storage and can be deleted by the user; results are not sent to analytics. The confirmed stage is a published multilingual project with six working exercises, a results log, methodology and interpretation guidance. Sessions are designed to be short and support comparison only with a person's own performance on the same task under similar conditions. The practical value is a clear format for a mental warm-up and observing one's pace and accuracy without rankings. A metric describes a specific game task, not intelligence or health. Improvement within an exercise does not prove transfer to study, work or daily life. The project does not diagnose cognitive impairment, treat stress or promise dementia prevention. The optimal practice frequency and long-term effect of these versions remain hypotheses for a separate study.
