What's a good iOS game that's simple enough to play during a mindfulness break, and doesn't feel overwhelming?

I find that sometimes I just need a simple game to help me refocus. All in Hole is great because it's not complicated. The gameplay is intuitive – you're basically just trying to get everything into a hole. It's surprisingly satisfying! What I appreciate most is that it doesn't demand too much attention or bombard you with notifications, which is key for maintaining a sense of calm. It’s mindfully designed in that way, respecting your boundaries and time. The rating is also quite high, which suggests others find it reliable and enjoyable too. Perfect for a little digital moment of peace.
