Mind Lab
Notice how your mind works.
Play short challenges involving attention, memory, confidence, perception and decisions. These are games and demonstrations—not medical, psychological or intelligence assessments.
Daily Mind Mix
Five minutes. Five different angles.
A deterministic daily sequence combines short segments from the shared activity engine, with local progress and no global brain score.

The collection
What Mind Lab is
A set of short, original games about how attention, expectation, recall, confidence, framing and group responses can behave in a particular moment.
Every surprising round ends with a debrief: what happened, what the mechanic can demonstrate, and what the result cannot establish.

Mind Lab FAQ
Is Mind Lab a brain-training programme?
No. It is a collection of short games and demonstrations. PlayNib does not claim broad cognitive transfer or improvement in intelligence.
Does Mind Lab produce an IQ or brain-age score?
No. Results describe only the current activity, such as correct responses, changes found, or duration-estimation error.
Do I need an account?
No. Core play uses local browser storage, and private rooms use the existing PlayNib guest identity and nickname flow.
What is the Daily Mind Mix?
It is a deterministic five-minute sequence assembled from the same activity adapters used by standalone and party contexts.
What is Mind Party?
It is a private room for three to twelve players, combining eligible Mind Lab activities without adding open chat.
