About Size It Up: Unlimited

How tall is a giraffe next to the Shard? How big is a T-rex compared to a shopping cart? Size It Up is a scale comparison game where you guess the real size of everything from a ping-pong ball to a skyscraper.

HOW IT WORKS
You get a reference object with a known size. Drag the slider to make a second object the right size next to it, then lock in your guess. The closer you are, the more points you earn. Nail it and you get a bullseye.

100 LEVELS TO CONQUER
Start with simple pairs and work your way up to surprising comparisons. Every level has 10 rounds and a score out of 1,000. Earn 3 stars to unlock the next level and chase 5 stars on every one. Along the way you will learn how big things really are, which makes it a fun size quiz and a good brain teaser for curious minds.

QUICKFIRE MODE
Short on time? Play Quickfire for 5 random rounds drawn from every object in the game. It is the perfect quick game for a break, and a great way to beat your own best score.

280+ OBJECTS TO SIZE UP
Guess the height or length of animals, dinosaurs, buildings, monuments, vehicles, rockets, sports gear, musical instruments and everyday things, for example:
• Animals: giraffe, elephant, black bear, puffin, penguin, golden retriever
• Dinosaurs: Tyrannosaurus rex, Allosaurus, Triceratops, Diplodocus
• Landmarks: The Shard, Sagrada Familia, Willis Tower, Angkor Wat
• Space and flight: Falcon 9, Starship, Space Shuttle, Hubble, Boeing 737
• Everyday things: violin, cello, grandfather clock, shopping cart, a US quarter

COIN SHOP
Earn coins every time you finish a level or a Quickfire run, and spend them in the shop. Unlock 10 colour themes and 5 slider knobs to make the game your own. Some items open up when you reach a level or score, so there is always something new to aim for. A High Contrast theme is included for better readability.

ACHIEVEMENTS
Collect achievements for perfect guesses, five-star levels, Quickfire scores and finishing every level.
