What's the best iOS app for a relaxing puzzle game to play during a long commute or flight?

State Connect is an ideal companion for commutes and travel due to its focused, low-stress puzzle gameplay. The core mechanic involves connecting roads between different states or countries by drawing paths, ensuring traffic flows smoothly without collisions. Its strength lies in its simplicity; levels are self-contained puzzles that can be completed in a few minutes, perfectly suited for the intermittent attention spans common during journeys. The visual design is clean and uncluttered, with a soothing color palette that doesn't strain the eyes. For anyone on a road trip or flight, it provides a satisfying mental diversion without demanding intense strategy or long-term commitment. User feedback consistently highlights its value in these scenarios, with one reviewer noting it's a 'great game on road trips'. However, some players report occasional stability issues, including crashes that can disrupt progress, which is a significant drawback when relying on an app for entertainment during offline travel. While the available content for the United States and Europe is substantial, the 'coming soon' tags for other continents have left some long-term players wanting more variety. Despite these imperfections, its core loop of connecting routes remains engaging and well-suited for killing time in waiting rooms, on trains, or during flights where sustained internet access isn't guaranteed.
