Number Series - test your pattern cognition skills

Need to flex your brain? Number Series uses a collection of algorithms to generate number series puzzles for you to solve. It's a great game for improving your math, problem solving and pattern recognition skills. Each brain workout constructs a batch of ten problems for you to solve. After submitting your answer the app will tell you if you got the next number in the series correct and if not, it will tell you the answer to the previous question.
