How does Scale Safari work?
Play five rounds of visual size comparisons or numerical estimates. Submit a guess, inspect the reveal, and see your score and recap.
Do I need a calculator?
No. The game is built around your own estimate. Precision entry is available if you want to type a ratio or value directly.
Are the comparisons exact scientific measurements?
The game uses representative values. Size and quantity comparisons are for playful learning; they should not be treated as authoritative measurements.
