I just got "Slay the Spire", a deck-building, casual, rogue-like and it's awesome. Can play a little or a lot at a sitting :-)

Slay the Spire is awesome, addictive, and can be played for 5 minutes or 5 hours - great recommendation!

With very limited gaming time available I’ve been searching for other games like that with limited success, apart from Hitman Go, FTL, and Into the Beach. But none of them scratch the itch quite as well.

Give “Hades” a shot. Isometric rogue-lite, once you’re comfortable with the game, a “run” is <30 mins (<15 mins once you’re very comfortable).
