Very good but…


To the developer – thank you for your response and your hard work on the app. The update with the shorter time makes it spot on terrific. Five stars to you!

My kids like playing this game but the time is too long. They want to shorten it to two or three seconds. This would be a simple add into the settings. Please add this feature. The time on the multiplication one is too short. Please make adjustable for kids of all ages.

Having said that this is a terrific app. With that one feature I think I would give it a four or a five star. Keep up the good work.

Developer Response

The latest release of Newton now allows this! After playing a few games, you'll be able to chose the time mode that you want, which includes 2, 3, 5, and 10 second games. I hope you try out the new update! 😇

Amazing game


This game is great. I'm playing and improving my fast-math skills at the same time! I love the extra lives and slow-down mechanic; they add an element of strategy to the game which is nice once you get the basics down. Playing Newton is always frantic fun. Easy to pick up. Highly recommended.



Great brain training, just as much fun as Newton - multiplication. The exercises are simple enough for anyone to pickup and play, yet maintaining your concentration over time is a true challenge! Addictive educational content that I love snacking on.
