Smart Games is a collection of challenging Windows Phone puzzle games designed to challenge your logic, memory, sensory and problem solving skills.
While the puzzle collection doesn't have many bells and whistles, it makes up for things by offering challenging, head-scratching puzzles. The game is initially free with plenty of puzzle levels and questions to solve. Once you're done with the free puzzles, additional questions and difficulties are available through in-app purchase.
Available for low-memory devices, while there is some room for improvement, Smart Games is a nice collection of puzzle games to pass the time with.
