Is it possible to make a bot for a browser game?

Question

C++ / C#

There is a browser game (like a chess field) there is a side view.
The task is to make a bot in c# so that it recognizes enemies and automatically attacks them.
The method invented by me - from below under the battlefield we have a ruler with our and enemy moves.
When hovering over an enemy turn, creatures from that cell are highlighted in yellow.
Is it possible to make the bot single out this color (creatures are circled right on the field) and before each new OUR move, look for a new location of all enemy creatures?

Answer 1

everything is possible.
But for a browser game, maybe it's easier to parse html-dom?

Answer 2

It's easier to deal with requests (if the exchange is via http) or listen to a web socket. Read and send data. Imitate moves, etc.
