I would highly recommend Monument Valley (1,2 and 3 is coming soon) as far as puzzle goes, for a quick arcade fix, I like Breakout 71 (with rogue-lite elements) and all games by Arnold Rauers (Card Crawl being my favorite, but by a small margin).

Here’s a quick selection from the top of my head, if you want I can go throw my app history for a few more :)
