In addition to classic board games, chess is still very popular. However, an opponent is always required for this. Since this may not always be available on site, you can look around for an opponent online. A large number of websites are available for this purpose.
Playing chess on the computer
There are many computer programs that you can use to play chess digitally. But most of them are chargeable and can only be played against a computer opponent. When you play a game in the browser, you often have the choice whether you want to play against a real player or against the computer.
Schach.de
