## What is 1023?

Will you be smart enough to take on the challenge?

1023 is a logic game where each finger has a value.

Thumb = 1
Index = 2
Middle finger = 4
Ring finger = 8
Pinky = 16
Then 32, 64, 128… on the next hands.

Raised fingers are added together to form a number.

The goal?
Count from 1 to 1023 as fast as possible without making mistakes.

Discover how the binary system works while playing
Beat your high score
Compare your score with other players
Customize your hands and unlock colors

Easy to understand… but very difficult to master.
