Adobe Flash has been the most used technology by websites for many years to show animations, to stream video and to create online games. Due to maintenance problems, caused by the numerous security flaws of the Flash plugin, and with the arrival of HTML5 technology that allows you to do the same things without the need to add external plugins or programs, the development of the Flash Player has been terminated by Adobe (final deadline is January 2022) and previously blocked by many web browsers, including Firefox, Google Chrome and even Microsoft Edge.
The result of this block led developers to abandon Flash for new websites and online games; the problem is that there are still many sites still in Flash, many interesting and still useful web applications to use and the vast majority of browser games, which are all in Flash.
It happens, therefore, that when you open a website with a flash content, a white box appears with the writing Flash is blocked on it (Adobe Flash Player is blocked or Adobe Flash Player is blocked) or, on other sites, a button that says Install or Enable Adobe Flash Player or Click to activate Flash Player, which if clicked does nothing.
For every time you open a site in Flash, to play the old ones again Flash games (if they haven't been converted to HTML5 yet), then it's important to know how to unblock Flash on major browsers, namely Chrome, Firefox and Edge for Windows PC, Mac and Linux. We will also see a free program that allows you to play Flash games without using a browser.

In Google Chrome, every Flash content or game no longer runs. When a light gray box appears, an icon in the shape of a puzzle and the words "Click to activate Flash Player" or Adobe Flash is blocked, if you click on the message or on the puzzle, nothing happens and the flash logo appears. To unblock Flash Player on Google Chrome it is necessary, first of all, download Ruffle, a plugin that revives Flash on browsers. Once installed, when you open a site in Flash, it can be unlocked by pressing the Play button that appears (which allows you to run the Ruffle plugin).

Click the Run Adobe flash box and then press the button Allow top left.

The program Flashpoint, for Windows, Mac and Linux, is a web game preservation project that supports content made in Adobe Flash, Adobe Shockwave, HTML5, Java, Unity Web Player, Microsoft Silverlight, ActiveX, and other web plugins that are no longer used today. The project includes three main components: a web server, redirector and launcher. All of these work in combination to create the illusion of accessing Flash content (and other technologies) on the Internet. Flashpoint offers everything you need to play classic web games. It has a library of around 38.000 web games and 2.400 animations. With FlashPoint, all Flash games will still work even after support is permanently terminated and Flash has disappeared from browsers and Windows.
Alternatively, you can also Download and play Flash games on your PC.
NOTE: Adobe announced that at the end of 2022 it will stop Adobe Flash support and Microsoft Flash Player will be automatically removed from Windows via an update. Flash can still be used (perhaps with some changes to this guide)
Finally, remember that you can still view Flash sites on Android and iPhone with a little trick.
