re: AHL
In the page of the game that you suggested, launch Inspector. Then choose Network tab, then choose JS (not XHR!) sub-tab.
There (likely at the bottom) there are some inconspicuous index.php invocations . They return angular calls from which pure JSON may be extracted.
I am not sure it's obfuscated on purpose. I think it's caused by the fact the AHL website runs on WordPress...
I am attaching a sample JSON I extracted from that page...
