Guess Size - Scale Game
Guess the real-world scale
Free · Designed for iPad. Not verified for macOS.
You see a dog next to a gorilla. A wine glass next to a child. One of them is drawn to scale. The other one is up to you.
Drag to resize the red silhouette until it looks right, then hit Validate. The real size appears, and you find out just how wrong your brain was.
It is called the Mandela Effect for a reason: we remember sizes we have never actually measured.
HOW IT WORKS
- A blue reference object is drawn to its true scale
- Resize the red object by dragging it, pulling its handle, or pinching
- Validate to reveal the real size and score up to 100 points
- Five rounds per game, 500 points to chase
DAILY CHALLENGE
Everyone gets the same five objects each day. Compare your score with your friends and find out who actually has an eye for scale.
PRACTICE MODE
Play as much as you want with random objects from a library of 60: animals, vehicles, buildings, furniture, everyday objects and a few surprises.
SHARE YOUR BEST ROUND
Every game creates an image of your best guess next to the real size. Save it to your photos and post it wherever you like.
No account. No ads. No data collected. Just you against your own sense of scale.
