Can you beat the AI?

A real puzzle from the app. In a 2024 study, many leading AI models got it wrong.

Alice has 3 brothers and 2 sisters. How many sisters does Alice’s brother have?

How it works

Five minutes a day. Your brain only.

01

Five puzzles, one minute each

A new daily challenge every day. The next puzzle gets harder after a right answer and easier after a miss.

02

Hints, never answers

Stuck? After 20 seconds you can get a nudge in the right direction. Missed it? You get one more try, then the answer and why.

03

Watch it add up

Keep a streak going, see a calendar of the days you played, and track how you do in each skill over time.

What you’ll train
