How many times did the horse trick work on troy and what is the story behind it?

The horse trick, known as the Trojan Horse, worked once on Troy. According to Greek mythology, the Greeks built a massive wooden horse and hid soldiers inside it, leaving it at the gates of Troy as a supposed offering of peace. The Trojans, believing they had won the war, brought the horse into the city. At night, the Greek soldiers emerged, opened the gates for their fleet, and ultimately led to the fall of Troy.
