I do, although not necessarily on purpose! Sometimes I end up getting so engrossed in the game I'm playing that I end up playing it far longer than I ever meant to play and then the time is gone!
Currently I'm playing Fallout Shelter which isn't generally the sort of game I'd play on a mobile device but I've found it's actually quite gripping. It basically follows people in a bunker after an apocalypse type event and you have to get them to progress and level up so that they're able to fight off invasions and things like that. It's a simulation type game but for once it's actually pretty good on mobile!
I'm surprised nobody mentioned Pokémon Go. I play as my mean to kill time while I'm strolling the alleys around. It don't go and wander too often though. Wish I could catch better Pokémon, or even a legendary one, but I'm just lvl 25 and right now levelling became a chore than something fun to do.
