## What is Estiball?

How many are bouncing around? Take a look, trust your gut and type in your estimate – no counting allowed!

Estiball trains your number sense: the ability to judge quantities at a glance. After every round you see how close you were, as a percentage of the correct answer.

CHOOSE YOUR CHALLENGE
• Kids: up to 10, 20 or 50 objects – bigger and slower, perfect for young children
• Adults: 11–100, 101–500 or 101–1000 objects – from warm-up to real challenge

CHOOSE WHAT BOUNCES
21 objects, each in its own world: balls in a pinball machine, bees in a meadow, fish under water, dinosaurs in a prehistoric valley, kites in the spring sky and many more. A live preview on the start screen shows your choice before you play.

SEE YOUR PROGRESS
• Your accuracy in percent after every round
• Your last rounds at a glance, so you can see yourself improving
• Play the next round with one tap, or change the difficulty any time

MADE FOR EVERYONE
• No account, no sign-up
• Available in 12 languages

Great for kids learning numbers, for families competing against each other, and for anyone who wants to keep their mind sharp in a short break.

How good is your number sense? Find out with Estiball!
