How hard is SpaceChem?
What makes it hard: systems — knowing how it works. You get through it by working out what the game is actually doing and coming back with a better build or a better plan, not by faster hands.
Who actually finishes SpaceChem
- Steam6.1%of everyone who owns it on Steam“Chief Executive Officer”about 17% of the ones who actually played it
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 .
