I am not finding where to place the breakpoint now.
I admit it has been many years since I worked with Javascript. I see a /game/18/js in the debugger, but the script is one very long line. Searching on shuffle bring no results neither does data-bytes. Random and promise appear a few times. But since it is now a single line script setting a break point doesn’t work. I currently just pile all the pieces together and move them around until I get a bunch joined up it is not fast, but doesn’t require much thought either, with luck I can get to 50% before I have to pay attention.
