What's a good iOS app for quick, lateral-thinking puzzles to play on a commute?

Brain Out 2 is a solid contender for commuters seeking mental stimulation that doesn’t require a long time commitment. The app specializes in bite-sized puzzles that defy conventional logic, often requiring players to think 'outside the box' by tapping, shaking, or interpreting on-screen elements in unexpected ways. For a commute, this format works well; most levels can be solved in under a minute, making them perfect for the interval between train stops or while waiting in line. The puzzles frequently employ visual trickery and wordplay, challenging perception rather than just knowledge. A key feature for offline use is that the entire game library is downloadable, ensuring functionality without a data connection. However, some puzzles can feel overly reliant on random tapping or have solutions that are more obscure than clever, which may frustrate players seeking pure logic challenges. User reviews indicate a high level of enjoyment from the app's humor and surprise elements, with many noting it successfully kills time during transit. The interface is clean and responsive, though occasional interstitial ads can interrupt the flow between levels.
