Most likely, you found that your favorite game is discontinued or would be sunset soon. We understand your concerns and we are sorry for the removal of these games. Unfortunately, we had to do this. The reason is that the games you are looking for are based on the outdated and obsolete Flash technology. This technology should be eliminated until the end of the year by Adobe company.
In fact, many browsers now block flash games by default. As a result, this Game Arena only supports HTML 5 games which are fast, reliable and responsive. In order to ensure top quality and performance for all games, flash games are, unfortunately, no longer supported.
Hope you will find our games engaging.
