About One Quick Try

One Quick Try is a collection of short interactive challenges built around one question: how did you do?

We make browser-based challenges for reaction speed, memory, perception and logic. There are 47 of them so far. Each one ends with a single plain result, such as a time in milliseconds, a score out of 20, a number of moves or the level you reached, the moment you finish.

You don't need an account, and there is nothing to install. Open a challenge, play it, see your result, try again or try another one.

What we don't do

• We don't give IQ scores, brain ages or any single number that claims to sum you up.
• We don't collect anyone's results, and we don't invent averages or percentiles. A few challenges rate your result against a typical result published by a named source, or against a puzzle's proven best answer; the methodology page lists every source.
• We don't offer medical, clinical or psychological assessments. These are challenges for fun and curiosity.
• We don't claim that playing makes you smarter.

How the challenges are built

Every challenge runs entirely in your browser: the timing, the scoring and the puzzle logic. Each challenge page explains exactly how its result is calculated, what can affect it, and what it doesn't measure. The methodology page covers what all of them have in common, especially how a browser measures time and why your device is part of every reaction time.

Where a page states a fact about a puzzle, like the fewest moves for the Tower of Hanoi or how many sets of four numbers can make 24, the number comes from code on this site that works it out, and the same code is tested every time the site is built.
