Halloway is one such puzzler that stands out. This text-based game sees you entering a mysterious, labyrinthine mansion and exploring its wings and rooms, solving puzzles based on the clues provided to you. It's a bit lacking in graphical flair (obviously), but there's an odd, almost surreal atmosphere to it. Because Halloway allows you to try out its free 'Foyer' level for yourself. And if that's still somehow not enough, you can always dig into our massive list of the best puzzle games on Android.
