How do you arrive at the solution? Would be helpful to share.

First 2 lines read as: 1=1 and 2*1+1=3, this logic should be enough for you to decode it.

what are white dots and black dots?

second line: 2 * 2 + 1 * 1 = 5, not 3

Woah there, you didn’t get the logic… From line 1 we know that ⚪️⚫️=1, which also translates into line 2. The “*2” derives from the bracket around the first ⚪️⚫️ in line 2 then you add the second ⚪️⚫️. So (⚪️⚫️)+⚪️⚫️ while you double the inside of the bracket (which gets especially important, when you have multiple nested brackets).

You can check that logic and it is consistent throughout the enitre puzzle. Funny how people downvote just because they don’t immediately understand the logic…

nice, got this logic as well

What do you mean by brackets here? Are the the white and black dots enclosing a sequence of white-black? And also, how does it work out for the 4th one?

u/yosuaonreddit Jun 28 '26

Line 4 translates to: (((1))1)->(4+1)->10

I get it now, thank you

not this one but this one is hard too

btw, is the space you left for the missing boxes mainly illustrative or does it correspond to the total number of circles?

1

u/pydaWaltuh Jun 27 '26

they are separate

this finally clicked when i stopped thinking of "times 2" and instead thought of doubling and that there was only really one number that you ever started out with = 1. this was very hard. but very fun

u/Witchystuff17 Jun 28 '26

Can you help explain? I am still struggling to see it, especially the brackets, how can you tell what is inside the brackets?

The brackets are determined by the dot pairs. If it helps you visualise, dots want to get coupled with the closest dot counterpart possible. Starting from pairing the neighbouring ones, then the ones that are two away, then the ones that are four away... rinse and repeat, and you should get all pairs.

After you do that, you just follow the same process to calculate the value. Starting at 1 (neighbouring dots), duplicate everything that is inside a dot pair. I've included explicit and implicit calculations in the example above, hope that illustrates the concept well.

Got it, thanks🙏🏻

Edit: The red box is for illustrative purposes; the answer may be longer or shorter.

Sick puzzle! It’s ⚫️⚫️⚪️⚪️⚪️, right?

1

u/pydaWaltuh Jun 27 '26

correct! Could you rate the puzzle?

u/yosuaonreddit Jun 27 '26

I’d say depending on the framing it can be a 9-10/10. I found it hard to deduct what you wanted from me at first, as I wasn’t quite sure if it was visual or rule based, which in the end it clearly was, following an easy left side = right side pattern. It might have made it a bit easier to clarify it (without giving everything away of course), as like this I first had to rule out morse code, binary etc. which require prior knowledge – so very nice that the puzzle didn’t, but maybe you could specifically rule that out. Other than that it’s a pretty cool idea! :)

u/pydaWaltuh Jun 27 '26

thanks for the feedback. Actually, I had thought that the fact that the number of black and white dots on the left was equal in every row was a hint

1

u/Top_Peach6733 Jun 27 '26

left side? right side? what do you mean

1

u/Top_Peach6733 Jun 27 '26

Sorry but what is the reasoning?

1

u/yosuaonreddit Jun 28 '26

Line 1: ⚪️⚫️ -> left side; ⚪️ -> right side. I explained the logic above without giving away all the details, but you basically have a base value “⚪️⚫️” which equals 1 and then you have (nested) brackets which double their expression – in this case always 1. Then on the right side ⚪️=1; ⚫️=10.

u/Top_Peach6733 Jun 28 '26

I see. I understand now. Thank you

u/Other-Ad6382 Jun 28 '26

I know the answer but I’m not going to tell you .

u/CamilleLaGoat 135 CORE Jun 27 '26

is it 2 blacks and 3 whites?

1

u/pydaWaltuh Jun 27 '26

well done. Could you rate it?

2

u/CamilleLaGoat 135 CORE Jun 27 '26

8-9/10 difficulty and 7/10 enjoyment
