There are a variety of board games available digitally through services like Steam or the App Store/Google Play.  Some examples are Ticket to Ride, Splendor, Istanbul, Lords of Waterdeep, Catan, Scythe, Terraforming Mars, Twilight Struggle, Raiders of the North Sea, and many more!  Most of these games allow for both solo play and online play with others.

Also, you can virtually play board games on PC by using the Steam program called Tabletop Simulator ($20).  It represents a game in virtual 3D and allows you to manipulate game pieces as if they were really on the table in front of you.  However, Tabletop Simulator does not simulate game AI or rules - you still have to do that yourself as you would in an analog version.  Tabletop Simulator must be installed on a computer.  There is a fairly steep learning curve but there are many videos on YouTube that can help.  On the plus side, there are a ton of games available in this format (some are free and some cost money).

Another popular option online is Board Game Arena. Board Game Arena is free and runs through a browser on either your computer, tablet or smartphone.  Some of the games offered are Sushi Go, Colt Express, Stone Age, Tokaido, Terra Mystica, Puerto Rico, Hanabi, Love Letter, Roll for the Galaxy, and more.  Board Game Area simulates game AI/rules for you and you can match up with players around the world.
