Overview

Cool Circuits is the challenging puzzle that dares you to complete an electrical circuit using eight seemingly simple pieces.

Start by choosing one of forty included paper puzzle cards and laying it on top of the puzzle box. The card illustrates a segment of the correct solution along with a smattering of hints as to how to place your pieces.

Cool Circuits are incredibly difficult to solve because each piece can be flipped as well as rotated in several orientations, and there is only one correct solution to each puzzle.

Portable puzzle box features pull-out tray for challenge card storage. Requires 3 x AAA batteries (which are included).

Cool circuits puts your brain muscle to the test!

The goal of Cool Circuits is straightforward: complete a circuit by correctly placing all eight pieces onto the grid according to the conditions on the puzzle card. Depending on the difficulty of the puzzle card you've selected, you could be in for a very long night.

Eight pieces, thousands of arrangements, only one solution

Despite having eight pieces you can arrange in a myriad of ways, each puzzle has only one unique solution. So you're probably not going to luck your way into the answer. Instead, you'll need to use your abstract thinking, spatial visualization, and deductive reasoning skills to solve these monsters.

Each Cool Circuits puzzle has only one solution.
There is only one correct arrangement of pieces per puzzle.

Enjoy the light show; it won't happen often!

Should you solve the puzzle and complete the circuit, a short music-accompanied light show will commemorate the occasion. Savor the experience because these puzzles are hard!

When you complete the circuit, the Cool Circuits board lights up.

Four levels of difficulty

Cool Circuits includes a total of 40 puzzles. They are divided into four levels of difficulty: tutorial, beginner, student, and advanced. Don't be fooled into a false sense of security by those names. Even the so-called beginner puzzles are no walk in the park.

Some of these puzzles are diabolical!

Cool Circuits has the potential to drive you insane. Because each piece can be rotated or flipped, there are seemingly endless combinations of arrangements. Combine this with a puzzle card that only provides a sliver of a hint, and you've got yourself a brain knot of Gordian proportions. Translation: good freakin' luck!

Cool Circuits puzzles are maddeningly tricky.

Portable puzzling right out of the box

Cool Circuits comes with 40 puzzles (which can be stored inside the puzzle board itself) and eight puzzle pieces. The small puzzle board is perfect for travel or riding in the car.

Frequently Asked Questions

Question: Do the puzzle pieces form an actual electrical circuit?

Answer: Yes! When all of the pieces are connected together end-to-end, the blue LED light show begins.

Question: Are batteries included?

Answer: Yes. Cool Circuits requires 3 x AAA batteries which are included.

Question: How does the puzzle board "know" that the circuit is complete?

Answer: Magic? We aren't knowledgeable enough about electricity to explain how it works. All we know is that it does work.

Question: Is it really as difficult as you say?

Answer: The advanced puzzles are extremely difficult. When various team members at Vat19 tested this item, we were at first embarrassed to tell each other that we had trouble with the "intermediate" puzzles. These suckers are hard!

Where can I buy this awesomeness?

Burning Questions: You Ask and We Answer

Burning Questions: You ask and we answer!
Your questions that have been answered by the Vat19.com staff:
Does it includes an answer booklet?
Yes. Each Cool Circuits set comes with a solution book if you get stuck.
Does it makes sound?
Cool Circuits plays short melodies upon completion of a puzzle.
What do the backs of the cards look like?
The cards are double-sided, meaning that there is a puzzle on both sides of the cards.
What happens if you arrange the pieces,but out of order?
Nothing happens, which is the problem. The pieces must be laid out correctly or else the circuit will not work.
Can I get shock if not used properly?
Absolutely not.
What batteries are used for this game?
Three AAA batteries. We mention this at the top of the page in the "Features and Specs" section.
Do you have to use the paper? Or could you make your own cool circuit pattern?
The papers are required as they indicate which circuit is being attempted. No, you cannot create your own puzzles.
Will the lights burn out?
LED lights last an incredibly long time.
This is awesome!! But its super hard. Any of the Vat19 staff able to complete them?
We were able to complete some of the puzzles, but there were a few towards the end that had our brains thoroughly twisted.
Are there anymore levels to this game as I have completed all 40 in a few days?.
No but you can always play it again!
What is the age for this game?
The manufacturer recommends ages 8 and up for Cool Circuits, mostly because the small pieces can present a choking hazard for younger players.

This information can typically be found at the top of the page in the "Features and Specs" section.
Did I see a Problem #0 or is there one?
Yep! It's less of a puzzle and more of a training grid which helps you get a feel for how Cool Circuits works.
This thing seriously awesome!!! How does the light come on?
We know a circuit is being made, but beyond that we chalk it up to pure electronic wizardry.
Can replacement pieces be purchased?
I'm sorry but we do not sell individual replacement parts.
received my CC the other day. We love it. there is a small white wire that protrudes from the back, near the on/off switch,. Seems to serve no purpose and is in the way. What is it for?
It sounds like you're referring to the wires that once connected to the "Try Me" button. They serve no other purpose and can be easily removed.
Hay vat19 I was wondering somthing about this product. if you wanted to make up your own way to connect the circuits do you have to use the cards that it comes with.
The circuits only work with the included cards.
How do u take the try me button off?
Simply pull it out. The "Try Me" button is only a wire with a plug.
Does this game make a sound when you win a puzzle?
It does! After completing a puzzle, the game board flashes and plays a short victory tune. There is also an option to turn the sounds off if you're playing someplace quiet (library, classroom, funeral home, etc).
If it doesn't work by the time it gets to my house, will you send a replacement?
We're always more than happy to assist with a refund or replacement should a product arrive damaged or defective. With that in mind, electronics do not usually expire in the mail.
Is this a good traveling game?
We would think so. All of the pieces and cards are contained in the base, and it's not as if you need a lot of room or a stable surface to play on.
How long is the battery life in it?
We don't have an exact number of hours. With that being said, you'd likely have to play nonstop (that is, 24/7) for several weeks to drain the batteries completely. In real time, that could be a a year or two. It just depends on how often and how long you play and the quality of the batteries.
Do you carry replacement cards and harder cards?
We do not, so be careful with the cards you have! There are no plans for additional cards at this time.
Can you remove the "Try Me" button and wire from the puzzle board?
Yup. You just have to pull it out. The "Try Me" button is only a wire with a plug.
What if I completed a closed circuit with less than all eight (8) pieces, or with all pieces but not according to the question card, would it still lights up?
There is only one correct solution per card, so even if you did find another way to close the circuit it wouldn't necessarily light up.
Looks like glow in the dark noodles.
Which are undoubtedly the best kind of noodles.
If I lose a piece, can I get replacement parts, or do I have to buy another game?
We're sorry, but we do not sell replacement pieces, but it may be possible to obtain replacement pieces from the manufacturer.
I watched the video of burning questions. So you ship to over 70 country. I wonder if you ship to Taiwan?
You can always check the Countries We Service list if you're ever interested in finding out which countries we offer shipping to. To answer your question, yes, we ship to Taiwan.
I have Cool Circuits and can't figure out how to disconnect the "plug" or wires of the Try Me. I've pulled, pried, broken finger nails. Otherwise, it's great, a big hit! Please help with more detailed explanation of how 'easy' it is to remove these
It should just pull right out. Check to make sure that there isn't anything blocking the plug, such as a little plastic piece that might need to be moved (like a phone jack).
How does the puzzle board "know" that the circuit is complete? please give a real answer.
Electrical wizardry. We're not entirely sure of the exact nature of the board; we just know that it works!
I don't understand what the "try me" button does. I have learned I can pull out the wires from reading your above posts, but I am not sure how I was to use it to "try" it out.
The "Try Me" button is pretty much only for retail stores where customers can take things from the shelves (Target, Toys R Us, Wal-Mart, etc). Pressing the button simply makes the toy light up and make noise so that the customer knows what to expect from it.
Can I laminate each card so I can use it for a really long time or will it mess up? I would of course cut out each hole. It will take a while but its worth it!
Laminating the card could prevent it from working properly, so we would not suggest doing that. As long as you keep the cards in their designated slot they shouldn't get too badly damaged.
Will you ship your comodity to Taiwan?
Yes, we ship internationally.
After a week my cool circuits did not work. I have put in new batteries and it did not work. It worked with the Try me button but not with the circuits.HELP
There's a tab which needs to be removed to take the Cool Circuits game out of "demo mode". Make sure that tab is removed, as it sounds like the game itself is functioning if the "Try Me" button works.
Did John actually have a hard time answering the puzzles? How far did he get?
Some of the puzzles are insanely difficult. We don't remember how far Jon got but he definitely struggled with some of them.
Has any of Vat19 solved the highest level puzzle?
Yes and it wasn't easy!
Is it frustrating?
Some of the puzzles are incredibly challenging, so it certainly can be!
Can you turn the music off and just have the lights?
The Cool Circuits Puzzle has three settings: On, Off, and Mute. The latter will turn off the sounds but keep the lights on.
Are the pieces magnetic?
The pieces are not magnetic. They are held in place by the pegs which they wrap around.
Why did you guys make the beginners so easy?
Because those puzzles were meant for beginners, hence the name. They're essentially tutorial level puzzles.
Could you take this past airport security or will they confiscate it?
It's just a board game. I don't think airport security will care at all.
Is this travel friendly?
You bet! The pieces can even be stored inside the unit so that they don't get lost under the seats.
What does the "try me" on the box do?
It causes the board and pieces to light up while playing a little song.
Are there extra pieces or anyway to buy any extras in case of the catastrophe that is losing a piece? (This is irrelevant however do you have a VAT19 app?)
Nope. You'll just have to be careful not to lose any pieces!
Does the light shine through the cards?
Yes, the light is bright enough to shine through the cards.
Does it come with the x AAA batteries
Yes it does!
I lost the instructions, but only want them to see solutions if those were part of it. Can I still download a copy of solutions?
That won't work. You have to have puzzle sheets in order to complete the circuits.
Will it give you shock?
No, the Cool Circuits game will not shock you.
Can I set up my own circuit. If yes will it light up?
Cool Circuits does not have the ability to let you create your own functioning circuits.
Can you electrocute someone with it?
No you cannot.
what are the cards made of? is it easily bendable? is it like paper, card stock cardboard etc.?
They're made of cardstock, so yes, they can be bent easily.
How long does the battery last and where do you buy vat19 coupons?
That will mostly depend on the brand of batteries and how long you play, but a single set should last a long time. You can sign up to get coupons via our newsletter here.
Are there more puzzles available for purchase?
Not at this time. Sorry!
Is there a way that you make your own puzzles by drawing on paper?
It doesn't work that way. Sorry!
What is the difference between hard and easy puzzles?
The harder puzzles offer fewer hints regarding where to place the circuit pieces.
Could I play this in the car?
I don't see why not!
The picture with Jon has a typo in bold! You are welcome to send me some coupons for pointing that out thanks
It's not a typo; it's Bostonian.
Have you come across any way to get another solutions book? Ours has disappeared and cannot solve half of these!
Oh no! You may want to contact the manufacturer.
Will a degree in electrical engineering be unfair?
Never!
Will it work without the problem card?
No it will not.
Does this ship to these countries below? Iraq,Norway,Denmark,Egypt.
I really want this on my birthday. Haw long does it ship to Finland or does it ship to Finland at all?
That will depend on the shipping method you select. Once you've added items to your cart you can view the available shipping methods.
Is this really a hard challenge, Because it looks pretty easy.
Looks can be deceiving and some of the puzzles are surprisingly challenging. You'll have to try it for yourself!
Could you make your own circuit?
You can only create circuits with the included overlays.
Can you bring this object all the way to Cairo, Egypt?
Yes, we ship internationally.
I live in Zaragoza, Spain and wanted to ask if you can make an exception and pay on delivery if shipping payment is also in cash. So, please, I really want this product!
I'm sorry but we cannot make any exceptions regarding shipping or payment. We do not accept payment on delivery, nor do we accept cash or personal checks. All orders must be paid in full at the time of checkout.
Where I can get missing 3d puzzle pieces,two are lost.
You may have to simply purchase a new set. The pieces are not sold individually. Our only other suggestion would be to contact the manufacturer.
Can you creat your own puzzles?
We're afraid not. You can only use the included puzzles.
Can I get one before December 20?
Sure! All you have to do is choose the appropriate shipping option when you check out online.
Is this too difficult for 7 year old?
It's tough to say, as it will depend on the individual child. The manufacturer recommends ages 8 and up.
What age is this game good for?
The manufacturer recommends ages 8 and up. We actually mention this at the top of the page in the "Features and Specs" section.
Can you ship to vietnam ?
Yes, we ship internationally.
Can you make your own puzzles with it?
There is not an option to program your own puzzles.
Are the batteries included?
They are!
It really looks like a Midi Fighter Spectra.... IS it supposed?
I think it's just a coincidence. There's only so much you can design with a square and some circles.
(1:20) seriously though, what exactly do you do there? do you just make your own path towards each other?
You got it!
Whats the song called in the background when he's saying: " Yes , yes, I am amazing..."?
We're not really sure. We get all of our music from a royalty free online library of songs, most of which do not have artists or titles listed.
If you lose a circuit piece, do you sell extras (just the pieces, not the game board)?
We do not sell extra pieces, so you'll just have to be careful not to lose any!
Will this toy die if i dipped it in water? My daughter loves dipping things in water :p
It is electronic, so yes, submerging the Cool Circuits game in water will almost certainly ruin it.
What does the On and Off thing on the side do?
It turns the unit on and off.
If there are only 8 puzzle pieces this can't be hard!
Really? Does that make video games easy because the controller only has anywhere from 2-8 face buttons? If it were that easy we wouldn't even waste our time.
how bright are the circuit lights?
Bright enough to be seen in a fully lit room.
Did you ship to Kuwait?
Yes, we ship internationally.
Do we need to replace the batteries? Do we have to take out the batteries when not in used to prevent something we don't want to? Please reply me! I am your fan!
Sadly we haven't been able to find batteries that never need replacing, so yes, eventually you will need to replace the batteries. It is not necessary to remove the batteries when the Cool Circuits Board is not in use.
So basically all you have to do is match the pattern with the card or what?
The pattern on the card is just the start of the circuit. It's up to you to figure out the rest!
How much does shipping cost to UK?
That will depend on the shipping method you choose when you check out online. Simply add an item to your cart and use the shipping calculator provided to see which options are available as well as how much they cost.
Because spacial-visual is one of the eight intelligences (according to the theory), would some people be better at these puzzles than others?
It's certainly possible. I think it goes without saying that certain people are better at some tasks than others.
Does batteries are included?
Yes, the required (3) AAA batteries are included.
If I dropped the pieces to water it still works?
We don't recommend dropping anything electrical into water. In this case you could very easily ruin your Cool Circuits Puzzle.
What hint does the final puzzle card have?
You'll have to find out for yourself!
Can you play without the paper?
The sheets are what determines which puzzle you're attempting to solve.

Please excuse the shameless cross promotions!
