Mobile games usually get a bad rep as they’re usually asset flips and/or MTX-ridden and/or ad-filled, etc., and I’m sure this is actually the case for most games on the app/play store. But are there any ones that are actually good, maybe just something to pass the time with?
Lichtspeer is a nice time waster, Roundguard is a Peggle-Roguelike. For on the go I can recommend Krumit’s Tale, Meteorfall, You must build a Boat, Hoplite, Shattered Pixel Dungeon , Reigns, Slay the Spire. I can also recommend Cryings Suns, Stardew Valley (of course) and Yes, your Grace.
Most are paid, but if you want to try a lot, get yourself a month of Play pass where most are included.
