Flash games were once a popular way to make money online. They were simple to create and could be played by anyone with a web browser. However, the rise of mobile gaming has led to a decline in the popularity of flash games. As a result, it is now more difficult to make money from them.
There are still a few ways to make money from flash games, but they are all more difficult than they used to be. One way is to create and sell your own flash games. You can do this through a variety of platforms, such as the Adobe Flash Game Development Kit or the Unity game engine. Once you have created a game, you can sell it through a variety of channels, such as online marketplaces or your own website.
