Traditional board games that I have played is congklak (https://en.wikipedia.org/wiki/Southeast_Asian_mancala), I think there is an app about that in Google Play. There is also dam-daman which is the Javanese version of draughts.
I used to be super interested with trading card games. In my school days, YuGiOh was a big hit, lots of us dueled before the first lesson starts where unfortunate students get their cards confiscated. Duel Masters and Pokemon were also quite popular. Some also played Magic The Gathering (MTG), where I love the funny/witty flavour text of the cards (the same case with Duel Masters - they came from the same company). MTG has the online version on Steam called MTG Arena.
Nowadays board game cafes are quite popular, I enjoyed Coup (like @Olympian1010) and Drakon (a board game where you take turns in creating tiles to get coin, and the tiles have their own power) when hanging out there with my friends.
