Monument Valley 

Monument Valley is one of the most beautiful and thoughtful puzzle games you’ll find on the App Store. In it, you’ll guide a princess through a series of architectural puzzles that look like paintings brought to life, moving platforms and rotating pieces of the environment to create a path, and then tapping to move the character forward.

The pace is slow, and the environment is soothing and peaceful, so there’s zero pressure to rush. That makes it great for gaming sessions where you want something relaxing but slightly brainy. Each level feels like a tiny, interactive piece of artwork, which is why the game has picked up so many awards and even two equally beautiful sequels that are worth checking out once you’ve played through the original.
