Which analytics?
I can see how many people play my browser games on my website through Awstats.
Awstats shows how many people accessed a certain file which is needed to run the game (under Page URL - Top 25). That stat equals how many people started to play the game.
I can also see under the heading Top Downloads, how many times the sound files (as an example) were downloaded (it's automatically downloaded once they open the game).
Awstats is normally included if your website hosting includes a control panel. Find it under "metrics"
