What's in the game
Today’s five tests
Reaction, Number Memory, Echo, Math Sprint and Odd One Out, with fresh problems every day.
An honest Brain Score
Every test scores 0–100 on a fixed curve printed right in the app. Your score is the plain average, with no made-up “you beat 99%”.
Your report card
Finish the five and get a vintage school report card with inked grades, a wax-seal Brain Score and a teacher’s remark to share.
Build the habit
A daily streak, a calendar of your scores, personal bests, a daily leaderboard and an all-time board. Second Wind lets you retake your weakest test once a day.
A new bonus test daily
Nine bonus tests rotate in for extra credit, from Number Hunt to Stroop and Rotation. Practise the daily five any time.
One-time extras
The daily Trials, every score and practice for all five tests are always free. Optional one-time extras, with no subscriptions and no timers.
What makes it different
A better result can never score lower, because every curve is checked. Every day’s problems are audited too: no repeated sums, exactly one odd tile per grid, and fair pad sequences.
It works offline with no account. Brain Trials is for fun self-measurement. It is not a clinical or IQ test.
