How do I play Who Would Win?

You are shown two contenders. Tap the one you think would win the fight or contest. The reveal then shows the defensible winner and explains the maths behind it · mass, energy, bite force, biomass, or attrition · so you learn why.

Are the answers actually correct?

Every matchup has a defensible winner backed by real, checkable numbers, and genuinely too-close-to-call ideas were left out. Matchups assume a neutral open arena with both sides motivated and no weapons beyond what the names state.

What does difficulty change?

Difficulty selects how counter-intuitive the matchups get. Easy shows duels most people get right after a moment; medium adds true coin-flips; hard adds the counter-intuitive ones where the obvious pick is wrong.

Why did the underdog win?

Because the numbers say so. A million rats is roughly 350,000 kg of biomass; a tardigrade survives a thousand times the radiation dose a human can; a sloth beats a cheetah over a marathon because the cat overheats after 400 metres. The reveal spells out the maths each time.

Can I print Who Would Win? as a worksheet?

Yes. Each matchup prints as a two-option multiple-choice question with an answer key, so a teacher or parent can take it offline.
