🧠 BrainRank

How BrainRank works

BrainRank is a set of quick brain games for fun and practice. Each game ends with a Brain Score on a 70 to 130 scale, so you can compare your own results over time and try to beat your best.

➗ Math Quiz

Ten mental arithmetic questions, from simple addition to multiplication with an extra step. Faster correct answers earn more points. Tips: work out the tens first, estimate the answer before checking the options, and don't spend too long on one question.

🃏 Memory Match

Flip cards to find eight matching pairs. Fewer moves and less time give a higher score. Tips: remember the position of each symbol by its row and column, and flip cards in a consistent order.

🔢 Number Sequence

Each question shows a row of numbers that follow a hidden rule, and you pick the number that comes next. Rules range from adding a fixed step to multiplying, squares, and growing gaps. Tips: look at the difference between neighbouring numbers first, and if the gaps aren't equal, check whether the numbers are being multiplied or whether the gaps themselves follow a pattern.

🧩 Odd One Out

Four numbers appear and three of them share a property, such as being multiples of the same number, perfect squares, or prime numbers. Pick the one that doesn't belong. Tips: test the common properties one at a time: even or odd, divisible by 3, 4 or 5, square, prime.

Brain Scores are for entertainment only. They are not a clinical or official IQ test and do not measure your real intelligence.
