I enjoy these games on iOS:
-Hearthstone (play it daily)
-Rodent Rush (puzzle game like chips challenge)
-Papers Please (difficult to explain, just have to try it)
-RCT Classic (need I say more)
-Old School RuneScape (easy to level up while in a waiting room or plane)
-Ghost Trick (timetravel puzzle game where you’re dead)
Yes I’ve used PC VR with my quest, but it’s not as nice as just putting the headset on and jumping into a standalone experience.
