ThinkFun Gravity Maze Builder from Kids 5 & Up - Logic Marble-Run Brain Game for Problem Solving - Hands-On Maze Design - Durable Child-Safe Materials - Develop Spatial Reasoning & Critical Thinking

I bought this for my 4 year old grandson so we could work on this together. We have had so much fun trying to get the marble all the way through the different patterns. This is an excellent trial and error activity. He is learning how to twist or turn the blocks in order to make a smooth pathway for the marble. I love activities that make kids think and this one is truly a winner.

If you've got a kid who loves puzzles this is great. My son loves building the towers and figuring out different patterns

My grandson loves this. We hope to get more.

Yet another logic game from Think Fun. This one is as good as any other.I adore the logic games from Think Fun. Ever since they published Stormy Seas and Rush Hour under the Binary Arts tag, I've enjoyed different iterations of their logic puzzles.This one utilizes gravity and a marble run type experience to teach spatial awareness and problem solving. This could be done with a 4 year old with some coaching and partnering.

My 6yo and I have had a blast building with this. We started out following the cards. Then he just took off with it. The imagination this opened up in my 6yo has been exciting to watch. So worth it.

There's a binder filled with cards for puzzles that vary in difficulty from easy to hard, catering to different age groups. While it might be tough for younger kids, teens and adults will find it more manageable. It's a great gift option and offers good value due to the variety of challenges and puzzles available for replay.

This is a simpler version of the Gravity Maze that is geared towards a younger child. My daughter, age 7, has enjoyed playing with this and she is able to work on it on her own, without me helping each turn. That is good to foster some brain game time and independent play. I'm not completely sure how long this will hold her attention for before she wants to do something more complicated.

This ThinkFun Gravity Maze Builder: The Logic Games for Young Creative Minds Ages 5 and Up is well built with sturdy pieces and a variety of them to promote brain exercise with various ways of piecing them together.
