How are the answers decided?

By arithmetic, not opinion. Every scenario was authored with a worked calculation using standard physical constants · latent heats, specific heats, tensile strengths, ρgh for pressure, ½ρv² for dynamic loads · and the reveal shows those numbers. Scenarios that could not be defended numerically were dropped during authoring.

What does "gives way" mean exactly?

Whatever ends the contest for that side: shattering, melting, snapping, buckling, burning out, boiling away, or simply being unable to continue (a torch running empty against an anvil, two cars spinning their wheels against interleaved phone books). Exactly one side fails in every scenario · the other walks away.

What changes with difficulty?

How counter-intuitive the contests get. Easy stays on scenarios you can reason out (a bathtub versus an ice block). Medium adds genuine coin-flips (a diamond versus a hydraulic press). Hard unlocks the reveals most people get wrong · one litre of lava losing to a tonne of ice, ordinary steel wire losing to spider silk, a Prince Rupert's drop beating a bullet.

Will I see the same contest twice?

Not until you have seen every eligible scenario once. The game tracks which of the 61 hand-checked contests you have played at your difficulty and cycles the whole pool before anything repeats.

Is the physics really correct?

Each explanation cites the constants it uses (334,000 joules per kilogram to melt ice, 101,000 pascals per 10 metres of water, 400 to 700 megapascals of surface compression in tempered glass) so you can check the arithmetic yourself. Real contests have messy details, so treat the verdicts as what the numbers say for the stated setup · that is the game's whole point.

About Which Breaks?

Which Breaks? pits two absurd opponents against each other · a steel baseball bat against a million glass bottles, one litre of lava against a tonne of ice, a rifle bullet against three metres of water · and asks you one question: which side breaks, melts, snaps, burns out or gives up first?

The reveal shows the math. Every verdict is settled by real physics with real numbers: the latent heat of fusion of ice (334,000 joules per kilogram), steel's fatigue endurance limit, water pressure growing one atmosphere every 10 metres, resonance pumping a wine glass past 50 megapascals. You don't just learn WHO loses · you see the two or three quantities that decide it, worked out in plain numbers, plus a one-line takeaway you can reuse on the next contest.

Difficulty scales counter-intuitiveness. Easy rounds are intuitive once you think for a moment (a warm bath versus an ice block). Medium rounds feel like a coin flip (a blowtorch versus an anvil). Hard rounds are the "wait, really?" reveals where most people confidently pick the survivor · the litre of lava freezes solid, the fat concrete bar snaps before the pencil-thin steel rod, the paper stack stops the pistol bullet.

The pool spans thermal physics, impact energy, fatigue, pressure, resonance, fracture mechanics and material strength, and the game cycles through every scenario before any repeat. Wrong guesses are the point: each one replaces a plausible intuition with a number.
