Is it really possible to download Minecraft for free?

Or are you kidding?

Minecraft costs money. Different on each device.

If it says it's free, it's a crazy or cracked version. Better keep your hands off it before catching any viruses.

And where can I buy the best that I have the right version?

Always in the associated shop pages of the official manufacturer.

On the PC this would be under: https://www.minecraft.net/...net/en-us/

In Playstation, Xbox, Switch, etc. In the respective console stores.

Thank you
