What is the Web site address to play minecraft?

I'm wanting to start playing Minecraft. I was wondering what is the correct website address to play?

While Minecraft can be played in-browser free of charge, it's not as fully featured(or as popular) as the paid-for downloadable program. You can do both at the this link-

https://minecraft.net/...craft.net/

Either pay $20 for full game (WORTH IT)
Oryou can play classic (demo)

Either way it's minecraft.net
