Flash games are simple, browser-based video games that were created using Adobe Flash technology. They became popular in the early 2000s due to their accessibility, allowing players to enjoy games without needing to download or install software. These games often feature straightforward graphics and gameplay, making them easy to pick up and play. Many websites, such as Newgrounds and Kongregate, hosted a wide variety of Flash games, ranging from puzzles to action games. However, the use of Flash technology has declined significantly since 2020, as major browsers have phased it out, leading to the end of many Flash games.
