17 toys · a new one every week

Test yourself

Scored to the millisecond or the decimal. Your best stays in your browser.

Come back tomorrow

Something new each day, and a streak if you keep turning up.

Numbers too big to picture

A trillion dollars, the distance to the Moon, the age of things, made into something you can spend, scroll or count.

Pointless on purpose

No score, no goal, no reason. That is the point.

What is this?

10minutes.fun is a collection of single-page web toys, each built to be understood in five seconds and put down in about ten minutes. Some are real tests. The reaction test times your click from the moment the screen turns green. The circle scorer fits your stroke to the closest true circle and measures how far your line strays from it. Some are daily: a new real product to price, a dog that remembers whether you came back. Some take numbers too large to picture and make them something you can spend or scroll. And some are pointless on purpose, which is harder to get right than it sounds.

How it works

Everything runs in your browser. There are no accounts, no sign-ups, and no server keeping a record of you. Your best times, scores and streaks are kept in your own browser's storage, on your device. Clearing your browser data clears them, and nothing is synced anywhere.

A new one every week
