Circuit Scramble

Really good time killer, especially for fellow math/logic geeks. A bit on the easy side, but interesting and fun nonetheless! However, it's INCREDIBLY annoying that some of the puzzles on endless mode are unsolvable. I'd think that it would be pretty easy to have some sort of validation with the random puzzle generator--e.g. a simple brute force algorithm checking every switch combination for a valid solution..

I thoroughly enjoyed Circuit Scramble, even if it was a little easy (nothing like simplicity to boost one's ego, eh?) - but I'm surprised nobody has commented on how fantastic the music is! I've had it in my head for the better part of a week.

Concept and implementation are perfect. Taught my 8 year old circuits! A few small suggestions. Show the current level on every screen. We keep losing our place whenever we go back to do older boards. And second, every board should tell the target number of moves.

Nicely done. It is actually my job to work with logical gate, all day long... And from level 80 it become quite challenging to get the 3 stars the first time. Graphical interface is a bit slow and boring though, can you speed up a bit the button 's movement ? That should be nice. Thanks.

This game is a little too easy. Most levels can be solved almost immediate by tracing back from AND gates from the goal. The very few levels that were challenging (about 5 out of 125) were interesting to work through. There rest weren't with my time, but I powered through hoping for the challenging levels. An OK game, light on the polish.

The game is really fun and is a very good one to pass time. But there is a small technical problem. When no inputs are given, all outputs are supposed to be in the high impedance state, and not high(as some of the outputs in the upper stages are). Might misguide students, but it's just a game! Great job though ;)

"help items appear as you discover them in the game" is what it says at the top of the help section. because of it not doing that I've had to leave the app several times to source info from the web before before returning to the app to further gameplay. also, I'd prefer to look at the finished level before moving on. it's annoying how it instantly exits the done screen to move onto the next level. i do like the game in general though.

A little too easy but fun none-the-less. If you're extending it then introducing feedback loops in the circuit, or specific components for latches or flip-flops could make it more difficult to find the optimal moves.

It's very good, but there is some little problems. Take a look at level 116: i got 3 lights for a 4-moves solution but it can be solved by only two moves.

Would prefer option to use real symbols, not text labeled chip graphics. Endless Mode generates occasional unsolvable diagrams; either fix or provide button that says 'unsolvable'.

I've enjoyed playing Circuit Scramble. However, after playing Endless mode for a few puzzles, a puzzle was generated that proved to be unsolvable (I tried every combination). I emailed the developer back on Nov. 20, but have not yet received a response back. I would have liked to have given this five stars, but I cannot ignore this bug or lack of support.

A great start for a first game. I look forward to seeing what you come up with next. Took off 1 star as it does stay a bit easy for me, and seems like a long time til the next mode is unlocked

Clever puzzle. Challenge is to solve each logic puzzle with no extra moves. Improves your thinking and visualization skills. I'm a computer engineer so I'm biased to like it. Haven't finished classic mode yet but it's a good relaxation game.

This app definetly helped introduce what little I had learned from Google into a visual representation, and definetly helped get me on my way. If I had to recommend to someone trying to learn logic gates and circuitry from scratch, this app would definetly be high up on the list. The reason I didn't give five stars is because it's a bit annoying not knowing how many "moves" you should try to get to get 3/3 stars or points. Other than that small detail, it's an exceptional tool for learners.

Everything about this game could be pretty fantastic. The controls are nice, the graphics are unique, and the concept is fun... One detail the programmer left out: the levels have no pattern of difficulty. You can go from a very detailed, in depth logic problem requiring 6-7 steps to solve, and then you're faced with a 2 step instant win level. There should be some sort of progression, in both levels of difficulty, and number of steps to solve. It's hard to know if my 7 step solution was good if it is followed by a 3 step. And the 3 step gets only 2... Circles-instead-of-stars-that-may-be-intended-as-LEDs. Calibrate, people.

Overall, fun app. Have issue that there is not a great help section, especially if you are stuck on a level, but with enough determination you can normally plow through most boards.

I hate to say it, but I had to uninstall this app. After spending hours learning, problem solving the levels, and then beating the game, there's no reason to keep it. I've never beaten an entire downloaded game until I downloaded this one. I guess I'm just bitter that it came to an end.

Completed level 125 first time with no mistakes (slightly disappointed by the lack of challenge). Great concept and a good game but why not expand to 10 buttons or even 12? It would give you virtually endless level opportunities.

I'm using an Asus Zenfone 2. Selecting level 1 always gives me the intro and then as soon as it ends, the game closes/crashes without warning. I'm unable to even beat the first level.

Maybe is a good game if the adds don't cover your buttons.. That's why I hate this game.. And hate all add who don't let play the game

As an electronics graduate I loved it...wht a fantastic time killer also it improved my logic bcoz I dedicated to vlsi field... but my suggestion is that when o/p is connected level completion occurred there is no time to see what logic we used that produces o/p so in between need time to see how it works

Hoping you add more circuits to this fun game. Then again, I already spend too much time on it. Endless mode is a blast!

Would have a 4 but the random stage algorithm sometimes creates impossible solution. Annoying when you've been trying to resolve it just to find out you can't.

Great concept and implementation! Some levels are way too easy, but the game is very enjoyable. It need more logic ICs implemented to raise the difficulty.

This game is so much fun, simple yet challenging and complex. The concept has been implemented in a way which is easy to play yet can have you puzzling for ages over each puzzle. Looking forward to the next new content drop!

Level 123 is possible in 2 moves, much under par. And Level 125 can be done by just flicking a middle switch

There are 4 lights. Just kidding. Fun but not as comprehensive as you'd like, pretty easy. I think I'd prefer to be tortured with the technocalities of how logic gates are made, could be some real anguish there.

Played through all 125 levels. And you have to think pretty hard to solve 100+ levels

Vintage graphics, no full screen ads (so far). A 3-input gate would be nice! Sometimes i had to reset because touch sensitive unintentionally read two clicks. May be a 500ms timer can avoid double clicks.

I really loved it but then I am software engineer and I like the simplicity of logic. Just occasionally it can put up an unsolvable level which is the only reason I removed a star

Wonderful little game, highly enjoyable. For me it was too easy at the end, could be much harder. Maybe timer elements could be introduced, or other things to be done before completing the level..

I love the game. I tried using it to teach my wife circuits, but it fades before she can see what she did to complete a level. Please leave the board visible after a level.

It's nice to see a game that makes math fun. The only problem I see so far is that I believe that inverters should be called not gates.

Great, but it should be made more difficult by NOT automatically looking for the correct combo, but instead make the user click a "DEBUG" button once they have set the inputs and switches, and penalize them if they are wrong.

But for an old electronics fart like me 95% of the puzzles was far too easy and I solved them 3/3 in like 10 seconds each. Still, great fun!

Think I finally found a randomly generated level that's unsolvable. Would love to see the solution

Should use the actual logic gate symbols though. Would be educational for people who don't know them and less confusing for those who do. Otherwise very nice.

I'm taking a discrete math class right now. Part of the material covered in the class is Boolean logic and circuits. This game is great for warming myself up for solving those types of problem.

Wish there was a game like this back in college. But that was many years ago before smart phones

Didn't take too long to complete with 3 stars on every level. Good way to test logic understanding. Would be good to port to a website. I know a few teachers who would love this. Thousands of students could potentially visit.
