It was designed to be suitable for investigating the balance between challenge and control by providing fine-grained and wide ranged difficulty levels. TagTiles can address a range of skills including fine motor skills, cognitive and social skills. Evaluation of the game showed that the children appreciated the game and that most of them were offered a challenge that was appropriate for their skill level.
