It's very easy how to check which version of the game you bought. Check the game case. If it says, Xbox One & Xbox Series X|S, then you have the Xbox One version of the game. If it just says Xbox Series X|S, then you have the Xbox Series X|S version.

Já foi mencionado que o primeiro ano do Xbox Series X não terá EXCLUSIVOS para ele, então todos os games serão para One e Series X

[Translation - It has already been mentioned that the first year of Xbox Series X will not have EXCLUSIVES for it, so all games will be for One and Series X]

You would have to check if the game was released on older gen or not. If it says it's only for Series S/X, then no. If it says it'll work on both the One and Series S/X, then yes.

A game can be optimized for the Series S/X but still work on both, but not always.
