Marble Math is an excellent example of how to merge quality game design with significant educational value. This app works learners through the sequence of understanding the question, tapping into knowledge to form an answer and creating a strategy for navigating the gameplay maze. Getting answers wrong is not an issue here as it is highly motivating to learn through making errors too. Take time to read the information pages to learn about all the features and customize the problems and levels. One of the most engaging, educational math apps we have played to date.
