What parents need to know

Educational value

Kids can learn how objects interact with gravity, motion, and momentum. Kids also exercise their thinking skills as they set up the chain of events that will press the red button. They must analyze the evidence, select objects, try out various configurations, and make deductions about what might work. Isaac Newton's Gravity HD offers a creative challenge with its physics-based brainteasers.

Ease of play

These are very challenging puzzles that require a lot of trial-and-error. The Level Editor, though, is very user-friendly.

Parents Need to Know

Parents need to know that while it lacks any denotation like "Lite" or "Free" in its title, Isaac Newton's Gravity HD is essentially just a trial version for iOS that has an in-app upgrade for $1.99. On Android, the game is offered as "Lite" for the free version or a full version for $.99. With the free iOS version, you can use the Level Editor to create your own puzzles, which is arguably the game's best aspect. This feature is only available in the paid Android version. The included puzzles are very challenging, and may frustrate younger children.

What's it about?

The goal of each puzzle is for a chain of events to end with the pressing of a red button. Kids have a bank of objects such as marbles and blocks that they rotate and drag into place. Kids tap to release a ball, which rolls down a ramp and sets the objects in motion. They can place objects with somewhat reasonable accuracy. Players earn points through successful gameplay and can use those points to purchase a limited number of hints for each puzzle. The Level Editor feature lets kids create their own puzzles.

Is it any good?


ISAAC NEWTON'S GRAVITY HD is an absolutely beautiful physics puzzle game with some very challenging braintwisters. As a trial version, this seven-level package offers a great representation of what you get for the full price. It's a bit disappointing that Namco didn't label the iOS app as a "Lite" version, but at least you can still get free access to the Level Editor, which is the app's highlight. You can build some pretty amazing Rube Goldberg-type mazes complete with buttons and gears, which can be loads of fun even if the pre-existing puzzles are too tough.

Families can talk about...

  • Encourage your kids to experiment with momentum and gravity by setting up a chain of events using everyday objects. A classic example is to set up a chain of dominoes.

  • Research Isaac Newton or Rube Goldberg with your kids.

Boy Brains, Unite! Worth every penny

This app captivates all 3 of my sons. The educational value is off the charts. If your kids like Legos, engineering, problem solving, and strategy, they will not tire of this game. Yes, levels can be very challenging even for an adult, but you don't have to complete a level to try another one, you get endless attempts, and there are even some hints. My boys think they are playing a game. I know they are learning physics and engineering (law of gravity holds, hence the name). I rated this Iffy because it honestly depends on the intellectual level of your children, however, I would not underestimate any child. My boys are bright, but NOT in a gifted and talented program at school. If your kids like Angry Birds - let them try this. You'll be amazed.
