Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison. Percentages are shown exactly as each platform publishes them — Pyroblast does not recalculate them or mix player populations together.
How hard is UNO™?
Where the challenge is: 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.
Finishing it
UNO™ has an ending, but nothing in its achievement list marks it clearly enough to trust — so there's no finish rate to show.

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.
- Xbox — Microsoft's published rarity percentage across Xbox players.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
