My husband and I play the more complex board games, especially train games, like Railways of the World, the Empire Builder series, and any 18XX game. We also enjoy other Euro games, like Carcassonne, Castles of Burgundy, Terraforming Mars, and Splendor. We play online via Board Game Arena, via Zoom or Meet, and in person with other gamers who are fully vaccinated at our local game club.
I enjoy WordScapes. You make as many words you can in a puzzle, plus you get bonus points for extra words. I joined a team that makes it somewhat interactive. Or you can just have the team to request hints. The weekend has tournaments and the whole team (at least the one I am on) contribute. It's a no stress team but we get really engaged when we are in the top 5 and get extra coins. It does have ADS in it, so I splurged and bought the no ad version. It is a game i play everyday.
I also been playing words with friends with my two sisters for years now.
And a relaxing but also some strategy is Fishdom. I like to play the match three game and then decorate the aquariums you unlock.
Board Games: recently been playing with family Tribond. Its a game that gives three words or phrases and you have to come up with the commonality among them. It's great fun and actually a game most of my family enjoys.
Go to boardgame geek and brouse their games. This site has reviews and how-to play videos of all sorts of games, including games that be played solitaire. If you like challenging games, try Terraforming Mars, AuZtralia, Castles of Mad King Ludwig, and Wingspan for solitaire play. Also many good games are available online for free on Board Game Arena.
One thing I've really gotten into during the pandemic is at-home escape room games. I did one with a friend recently, and we even had to use the box to solve a clue. It was really clever, fun and challenging!
