## What is Let's Scale?

How many times bigger is a whale than an elephant? Or Jupiter than Earth? Let's Scale is a size comparison quiz: drag to guess the size, then see how close you got.

Animals, countries, planets, famous buildings and vehicles. A daily challenge with five new matchups for everyone, quick mini-games and duels with friends.

Move the slider until the size looks right, then check your guess against the real thing: the closer you are, the more points. Many objects come with a quick fact.

WORLDS
• Animals: insects, birds, savanna and ocean wildlife, dinosaurs
• Countries & islands: compare their area with a country you know
• Space: planets, moons and the Sun
• Transport: from a scooter to an airliner
• Architecture: famous buildings beside a bus
• Mixed: objects from different worlds side by side
• Earn up to three stars per level. Complete a world to unlock free play

DAILY CHALLENGE
• Five new pairs every day, the same for everyone
• From day two of your streak, get +10 % challenge points per day, up to +100 %
• A weekly freeze saves your streak if you miss a day
• Catch up on missed days in the archive covering the last seven days
• The top three in the daily and weekly results earn bonus points

MINI-GAMES
• Bigger or smaller: 60 seconds to tap the bigger one, until your first mistake
• Sort by size: arrange four silhouettes from smallest to largest
• Impostor: spot the wrong size among four silhouettes
• Duel: play five pairs and send a friend the code. They get the same pairs. The winner takes both players' points
