About BrainRank
BrainRank is a free website with short brain games you can play in a minute or two, on your phone or computer. There is nothing to download and no account to create.
Why we built it
Quick mental challenges are a fun way to practise mental arithmetic, spot patterns and sharpen your memory. We wanted games that load fast, work on any device, and give you a score to try to beat.
Our games
Math Quiz: ten timed arithmetic questions that get harder as you go.
Memory Match: find eight pairs of cards in as few moves as you can.
Number Sequence: work out the hidden rule and choose the next number.
Odd One Out: three numbers share a property, so find the one that doesn't.
Questions are generated randomly, so every round is different.
About the Brain Score
The Brain Score is a fun number on a 70 to 130 scale based on your speed and accuracy in a game. It is for entertainment and self-challenge only. It is not a clinical or official IQ test, and it does not measure your real intelligence.
How the site is funded
BrainRank is free to play. The site may show advertising to cover running costs.
