About this game
How Big Is That? is a size-guessing game where Milo the Mole shows you a reference object with its true size, then you drag a slider to scale the mystery object until it looks right. From a grain of rice to Mount Everest, with trick rounds like a blue whale next to a bus, this cheerful browser games pick is classroom-friendly and plays in quick rounds. Take on the Daily challenge or a Free Run, chase bullseyes, and climb from Rookie to Legend.
How to play
- Look at the reference object and its true size on the left.
- Drag the big slider, or use the Left and Right arrow keys, to grow or shrink the mystery object on the right.
- Tap Check the tape. Milo reveals the true size and your score from 0 to 100.
- Watch for Trick rounds: a blue whale next to a bus, or a grain of rice next to an ant.
- Play the Daily for the same 5 rounds as everyone today, or a Free Run of 8 fresh rounds.
Tips
- Start from the reference size: if the mystery object looks about twice the reference, it probably is.
- Scores use a times-bigger scale, so guessing twice as big and half as big score the same.
- Trick rounds pair look-alikes: slow down when the two objects seem close in size.
- A bullseye is 95 or better. Three bullseyes in autumn complete the seasonal quest.
