Step 1: Guess 00000.

Step 2: Replace all grey cells with 1s.

Yea, you don’t need more than two chances.
and now we know how raid parity works
This is some how the most concise description of parity ever
Came here to present my strategy for solving it in two tries, and realized it was far more complicated! (started with 00011)
I think it's actually possible to win on the second guess with any initial input. Or at least I did it a handful of times..
This should be correct. For any cell that isn't green after your first guess, there's only one other possibility for its value.
Yes. Yellow and grey mean exactly the same thing in this game: Flip it.
Hoping that you are being sarcastic...
It's not guaranteed you will always win in 2 steps because occasionally you will win in 1 step.
Isn't 1 within the bounds of 2?
There's a difference between "in 2 steps" and "within 2 steps".
Splitting hairs seems like grammar policing. I can even see action 1 and null action if I squint hard enough.
Step 1: Guess anything

Step 2: Flip all the non green cells.

afaik, guessing anything not 00000 or 11111 at first step will lead to an optimum strategy of 3 steps. because you introduce possible "right digit at wrong place" as a third state.

guessing 00000 or 11111 removes that third state and leaves you with simple substitution of wrong cells, which leads to an optimal 2 step strategy.

but obviously the shortest strategy is just guessing it right on the first try :D lol

It's still two steps. You only ever need to flip wrong digits.
It doesn't matter.

Right digit at the wrong place = wrong digit = you should flip it.

This puzzle won't take more than 2 guesses no matter what you input the first time.

And for a second, I was proud that I solved mine in 3 steps...

This is obviously improper. The valid strategy for this game unfolds as follows.

Step 1: Guess 11111.

Step 2: Replace all grey cells with 0s.

Thank you for your careful consideration.

If you start with 0's you save a small amount of electricity. 1's use up more electricity - any electronic engineer will agree.
Not to ruin a joke, but does it actually make a difference for SRAM? It’s two inverters in a loop, despite not being the same size they are active components. But I’m also a software guy so I could be totally wrong.
I think displaying black or white pixels makes a bigger difference.
> does it actually make a difference for SRAM?

I have no idea in practice. But for the thermodynamic limit of actually making a difference, any irreversible change requires heat to be generated, e.g. initializing to zero, truncating, or bitshifts with discarded information. In contrast, addition/subtraction/multiplication/bitshifts without over-/under- flow will not necessarily generate heat.

PS. you can also use mass-energy equivalence to extend this to calculate the lower limit of mass for a given quantity of information. TL;DR: The internet weighs 50g https://www.youtube.com/watch?v=WaUzu-iksi8

I intended this strategy, but 00000 happened to be correct, so I didn't even need a step 2.
Feedback: I'm unable to input with keyboard after typing anything but '0' until a full refresh (and selecting the input area with mouse).
You may not need the refresh, with Safari I have to select the game board again after focus is moved by clicking "play again".
Is it possible to get yellow cells?
Use a mix of 0s and 1s, if the answer is "00110" and you put in "11000" you'll have 4 yellow and 1 green. If you use only 0s or only 1s for your first guess, you'll just get green and grey, no yellow.
Huh, surprisingly difficult to get. Took me 8 or so attempts.

I somehow got lucky and guessed the answer in just one try lol
How lucky of you. You had one chance out of 100000.
I guessed 00000 and won first go!
hmm. I guessed something different (010001 maybe, I cant remember) and won first go too. I looked in the comments hoping to find the joke. I guess I'm 1 of the 10 people who don't understand binary jokes.
Good one! I'm the other of the 10.

Got it in one on my second game! Felt pretty good till I realized that's like 1/32 chance.
The probability of getting it right at least once in your first 2 attempts is even higher (6.15%).
Bit masking : the game
Got it in 10.
I was a bit sad, when it didn't display my number of tries as a 10.
There’s 10 types of people in this world: those that get that joke and those that don’t.
There are 2 kinds of people in this world, those that can extrapolate from incomplete data.
And fence post errors.
And those who know this joke is actually in base 3. :)
It should be solvable in no more than 2 moves.
Feature request: a "share" button, à la base-26 Wordle.
Yea, it’s too easy. Maybe if it were a “guess the number” but in binary? Hints are just “too high” or “too low”?

…though now that I’m playing it in my head that’s too easy too. (Start at MSB and shift right if too high and add bits if too low)…

Maybe if you reduced the number of guesses to 5 that’d add enough chance to make it fun?

It's not supposed to be fun or hard, it's supposed to be funny. It's absurdist humor.
Binary is too easy, but hex can be tricky. I made a hex-based wordle puzzle for my programming game where you have to guess an 8-digit hex string in as few as 6-12 guesses using wordle mechanics... called the level "dwordle" :)

(video from like 3 years ago: https://www.reddit.com/r/Unity2D/comments/sq4anb/i_added_a_w...)

Someone should make a base-26 version! It would probably be super popular!

Isn't this just Mastermind?
No, this is much simpler.
More like Minionmind.
Apologies for opening a tangeant on a tangeant, but am I the only one who thinks there are 2 levels of playing master mind (and therefore wordle)? Easy level, you let the player know exactly which spots are correctly placed and which ones are there but incorrectly placed. Hard level, you let the player know only that some are correctly placed and some are there but incorrectly placed without identifiying which ones. I personnaly don't enjoy the easy level when playing mastermind, but I do enjoy the hard version which is much more investigative and in my opinion triggers the same brain process as when I'm debugging code.
I don’t think I’ve ever seen Wordle implemented in what you call “hard level”. But there’s no reason it couldn’t be.
My wife took one look at this and said “It’s not Wordle if it’s all binary—it’s Digitle.”
Reminds me of the idea of analogue cheese - fake cheese. It's analogue cheese until you get some on your fingers, when it becomes digital cheese.

So, this can be solved in at least one and at most two attempts.
I think I don't get it... since it's binary, it can always be guessed in two attempts?
Yes. You can still try to get it in one attempt.
Odds in one attempt: 1 in 32

Odds in two attempts: 1 in 1

Ooops:

You won!

You guessed 01111 in 4 attempts!

Well yeah and a fair coin has P(heads) == P(tails) == 0 for someone who eats it.
Your odds add up to more than 1.
Odds of getting it within 2 attempts is 1. Odds of getting it on exactly the second attempt is 31/32
Probabilities sum to 1.0. Odds don't sum.

I’m glad I figured that out after my first attempt. I feel smart lol.
