One if my favorite games from the early days and even still is Dungeon Ascendance. https://play.google.com/store/apps/details?id=com.seramygames.dungeonascendancepaid
Puzzle like game. I STRONGLY recommend switching to classic graphics in the menu...the "new" graphics are a bit hard to look at IMO. There is a free version.
Gonna go ahead and add to this list by going with my old friend Dungeon Ascendance.
Even though I haven't played it much in the past couple of years it's, by tradition, always the first game I install on a new phone.
Great roguelike puzzle game that really captured my attention when I first got a smart phone.
Just some advice tho: A couple of years ago the dev came out with a new graphical tileset (which you can see in the screenshots). With all due respect, THEY ARE AWFUL. There is an option in game to use the old graphics.

It's a little old and has problems sometimes where progress is lost on newer android versions.
But Dungeon Ascendance. it says it's a roguelike game, but don't let it confuse. It's a puzzle game. Enemies don't move and only counter attack. You have a variety of 1 floor dungeons that you have to clear with different classes, each class and dungeon have it's own quirks for how to clear it, and it's figuring that out and managing when to use MP/potions. Harder levels are really unforgiving. The key is to maximize bonus exp from killing higher level monsters and keeping lower ones alive to easily kill them for level ups when you're out of resources/other options.

This really gets my praise for how unique it is. I can't think of anything similar.
BattleHeart is a solid game for a week or so.
If you're on android: Dungeon Ascendance
