Confused about Blynk

Ok, so I think that using Blynk may be a little too complicated for me right now, and am switching the interface to the internet webpage instead. I'm wondering how to publish a message on the webpage signalling that the user wins or vice versa, if one side goes over 21. For example, from this link

, I know that I need to use the Particle.publish () function, but that needs the user to prompt the button for the message to be displayed. I'm wondering if there's a way to do that automatically.

Also, a huge part of my program just runs om the IDE without much interface with the hardware itself. I just need the Photon to display the sum of the cards the user is dealt with, and turn on one of two LEDs signalling the player's decision.
