Ticket to Ride is fun to play on mobile with CPUs or with Friends. One time purchase per game board.

Doors games are fun puzzle games. IAP to unlock levels

Knotwords is a fun wordle/crossword puzzle type game. Subscription or one time purchase.

Night of the Full Moon. Slay the Spire esque game with multiple IAPs to unlock new characters/ Remove ADS(Which I would recommend) but you can try for free.

I’ve been reading Carrion Comfort. Really cool mystery story with people that can mind control. You’re always trying to figure out what the Game is and what are these pawns accomplishing.

Its a little long winded but Dan Simmons can write a compelling story.
Def more Horror than Science Fiction.

Been really enjoying Night of the Full Moon. Slay the Spire like but the opponents have decks and play like players. It’s free to play with expansions and an ad free experience you can pay for. https://play.google.com/store/apps/details?id=com.ztgame.yyzy
