How hard is The Binding of Isaac?
What makes it hard: execution — reflexes, timing and precision. You get through it by getting better at playing it — dodges, parries, muscle memory — not by turning up with a smarter build.

Same game, three different crowds. Steam, PlayStation and Xbox each work these percentages out from their own players, so the numbers move around while the game stays exactly the same. A lower number doesn't mean it's harder on that platform.

How rarity is calculated
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison.
- Steam — Valve's published global unlock percentage across Steam owners of the game.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
