You must be confused; You need 7-zip or some other program to extract the game. If you already have 7-zip or similar, right click on that 'word' file. The following explanation is for 7-zip, but it should be similar to whatever you use. You should see an option called 7-zip. If you click on it, you can either open the archive, which is in reality that .rar file which has been mistaken as Word and put it in a folder. You can also just do 'Extract here'. I hope this helped!
