About Which is heavier?
The fastest way to test your weight intuition: two real objects appear, you tap the one you think is heavier, and the weights are revealed instantly. Every correct pick extends your streak — one mistake ends the run. The pairs always differ by at least 30%, so there's always a right answer, but your gut will still betray you more often than you think.
Warmed up? The Daily Challenge asks the harder question: not just which is heavier, but how heavy exactly. Or browse all object weights to study up first.
FAQ
Is there a daily limit on Which is heavier?
No — play as many runs as you like, any time. Unlike the Daily Challenge, this mode is unlimited practice.
What ends a run?
One wrong pick — your streak resets to zero and you can start a new run immediately. There are no lives or second chances within a run.
How different are the two weights shown?
Always at least 30% apart, so there is always a clearly correct answer — even when your gut instinct says otherwise.
