Board Game Arena

How can I find out how many different games I have played on BGA?

Different games as in differebt type of games or different tables?

Both can be found on profile.

XP tab next to recent activity for the different type of games, net to it is the number of games you played as a whole.

There's no count, though.

Search the site for "victories" and see the result number

You can filter the Games in the Games Tab to show only the games you have already played.
