← Play Cosmillion

A daily brain game for adults, in 3 minutes

Most of the day, the first answer that comes to mind is good enough. Cosmillion is a short daily workout for the opposite: thinking past the obvious. Seven prompts, 25 seconds each, and the rarer your answer, the higher you score.

Why it works your brain

It rewards a second thought. Ask anyone to “name a spice” and most say turmeric or pepper. Those score +10. Dig a little further, to something like grains of selim, and it scores +100.

It mixes everything. Food, places, science, history, music, words, sport and everyday life, so every day stretches something different.

It's short and timed. 25 seconds a prompt keeps you quick and focused, and the whole game takes about three minutes.

You learn something. After each answer you see how rare it was, and you meet answers you might never have thought of.

A habit that sticks

There is one new set of prompts every day at midnight India time, the same for everyone. Keep a streak, beat yesterday's score, and challenge a friend with the same seven prompts.

It's free, needs no account and works on any phone or computer.
