About this game

Once a day. 60 seconds.
People all over the world take on the exact same challenge, and you get your Mind Index as a single number.

■ Three quick tests (numbers and shapes only)
- Reaction: tap the moment the green circle appears
- Arithmetic: solve as many as you can before time runs out
- Memory: recall the order the tiles lit up

Every test uses only numbers and shapes, so anyone in the world plays on the same field.

■ Your result is one number
When the 60 seconds are up, your Mind Index appears as a single number. See your balance across reaction, arithmetic, and memory at a glance.

■ Same problems, same day, worldwide
Today's problems are the same everywhere. See where you stand in the world as a top-N%. The number moves while results come in, and settles the next day.

■ Once a day only
You measure once a day. That's what makes today's number mean something. There's no endless retry.

■ Your daily record
Check the change from yesterday and your streak. Compare today's you with yesterday's you.
