ScienceWiz Cool Circuits Puzzle

We got this as a present when my son was 7 and years later we still have it. There are 40 levels to solve, getting increasingly hard. In each, you get a template for part of a loop and you have to fill that in then complete it with the remaining pieces. This involves turning and rotating the shapes and it gets quite hard. Seriously addictive, and you can play again and again as if you're like us you'll forget how to solve them :)

I can't understand the 1 star reviews that claim the pieces won't stay placed. This is absolutely not a problem - are these people playing it upside down?!?The puzzle's start out easy but rapidly get harder and harder to solve. I went back to playing mine again recently after 2+ years. The batteries are still working! I tried a harder level and was completely stuck so I went back to the #1 - it is a challenge to progress through each level and so much fun to figure out the reasoning axioms to eliminate possibilities in order to solve each puzzle. It can be very surprising how the shapes can get from one circuit ending to another!I love this thing!

Well packaged bought as a gift.

This is a brilliant puzzle game, and it can offer a lot of interesting play for a kid (and even an adult!)However, it suffers a major technical problem. The pieces won’t stay down; they always keep popping up even after trying to firmly press them into place. The mechanism used to try and make an electrical connection between pieces is finicky and puts pressure on the pieces, causing them to jump out of their place.This then means even if you manage to get them all to sit flat (a minor miracle), even when successfully completed, the box often does not light and and music doesn’t play.The idea is sound. The execution is poor.We’re returning ours for a refund because this game is killing my daughters’ desire to actually try to play it, as it pops out her carefully placed pieces all the time, and as pieces often need to be repositioned and trialled in other spots, this is a significant problem.Happy to buy it one day once again when they figure out a new way to get pieces to sit without popping out.

oh my goodness this puzzle is amazing , so addictive I am a teacher and bought this for our grandson aged 7 ..... Hope I don't wear the batteries out before I give it to him ... I work with a autistic boy who is very high on the spectrum I took it into school to see what he made of it ? he was transfixed gently putting the circuits in place and then so thrilled when the lights and music started ..... WELL DONE .. If you want me to try and comment on some of your other "SCIENCE WIZ" feel free to email me happymarycarter@gmail.com

Great little toy. Certainly kept my mind busy as well as the 8 yr old I brought it for.

I bought this for my soon to be 13 year old extremely intelligent daughter. The puzzles start super easy and start to get more difficult - absolutely brilliant. Would recommend year 6 upwards.

My Son loves this, highly recommend. My Husband and I have joined in the challenges too.

Good one
