Harry Potter Gryffindor Where Is The Gryffindor Gobstone Game In Harry Potter 5?

Where is the gryffindor gobstone game in Harry Potter 5? - harry potter gryffindor

I play Harry Potter 5 Wii.

I have for the game Gobstones Gryffindor and they do not find everywhere. I beat players (still working Hufflepuff Ravenclaw and Slytherin) Do I beat them all before I can play, the player of Gryffindor? Can you tell me where to find the game Gobstones Gryffindor?

Thanks
