Fun Apps To Pass The Time.

Lately I’ve been working 16 hour shifts and I’ve been really bored during transit and breaks ‘cause I don’t have anything to look forward to. I’d play subway surfers or block blast but even those have gotten boring. I’d read webtoons but the ones I’m reading update slowly and I don’t use socials like TikTok or instagram so I can’t waste time like that either. What games/ apps on the AppStore (preferably free) do you guys use?
