I have rarely encountered a game made specifically for the mobile market to be good. There are some ports of, what I call, real games that work well on a phone. There are some open source versions of things that exist on PC that give the same experience on a phone (like OpenTTD being a nice "rip off" of roller coaster tycoon).
There are only two made for mobile games I can even really give praise to: Galaxy on Fire 2. It's as good as those kinds of quick play arcadey space games can be without going full on Elite or Star Citizen. Perfect for a phone. The other was Synapse and I don't even think you can find it anymore. It was, at the time, the only turn-based tactical game like Firaxis' X-Com games. But since both of the newer XCOM games are officially on the phone, it's not a genre devoid of good stuff.
Half the time I hear about a mobile game getting popular or is touted in these kinds of questions threads, it's something like Clash of Clans. Just crap that lets you play for like 15 minutes every 24 hours unless you start shelling out money. ๐ฎโ๐จ
