There are a few things you need to do in order to publish your own board game. Firstly, you will need to create a prototype of your game. This can be done by either hand-making it or using software like Photoshop or Illustrator to design it. Once you have a prototype, you will need to find a printer who can print your game. Once you have found a printer, you will need to get your game manufactured. This can be done through a number of different ways, such as going to a game convention and finding a publisher there, or contacting a game company and asking them to manufacture your game. Lastly, you will need to market your game. You can do this by creating a website for it, or by contacting game stores and asking them to sell your game. By following these steps, you should be able to publish your own board game.
