Need help with Image guessing game (C socket programming)

this is the rule of the game: The game consists of two players and one server, where each of the players can only communicate with the server (but the other player). At the beginning, when the two players log on to the server, the server sends both of them a same image. The game then starts; the players submit words or phrases to the server, one at a time, without being told what the other player has inputed. The goal for both the players is to enter a word or a phrase that has been submitted by the other as soon as possible. Obviously, in order to maximise the chance of getting a match, the two players would better to enter words that describe the image well, since it is the only information shared by both of the two. (The image is, therefore, tagged.) Once the goal is achieved, the game ends; the server sends a web page indicating that the game is completed and prompting the players to play again. If both the players agree to play again, the process repeats I will provide the spec if ur interested
