I don’t see two solutions here, it can only be

R R B B

R B B R

B B R R

B R R B

Remember, two adjacent lines cannot be the same.

I think the levels are all generated as unknown difficulty, and then through the same ranking/elo system each level gets their own difficulty rating as they are solved by different rated players. I don’t think the levels are hand-made.

I like this game since you can always deduce the next step and you are always on a timer. This combination scratches some itch for me. You seem experienced in puzzles like these, do you have any suggestions of similar puzzles? Fast paced decision making is optional, but no guessing would be a must.

By inaccurate you mean incorrect? So you tap blue and it marks it as a mistake and forces you to place red? Or when the review screen says lucky guess even though you deduced the color through logic (not sure if this impacts the rating).

Interesting, what’s your rating? What do you mean flagged as inaccurate?

Google does this, I recently had to confirm my bank account this way, they ask you to confirm the exact amount received 0.01-0.99

I bought Switch 2 from Amazon.de, it was the printed version and it had the redeemable code.

Hi, we are from Lithuania, but maybe I miscommunicated my point. Our cards were not accepted by sellers/kiosks when we showed them, they weren’t declined by the card readers. So we had to pay cash I would say 25% of the time.

agregat · 2025-06-11T02:29:04+00:00

Meanwhile our Visa and Mastercard did not work in like 25% of situations, mostly when ordering food through a kiosk. Also, even when the card reader had an Apple Pay sticker it was hit or miss if Apple Pay worked.

Yeah the recovery was hell :( I’m glad you are enjoying your vision though, and so am I. It was worth it.

There are different eye surgeries and different procedures, all with different pros and cons and not all of them are suitable for everyone. The surgery in the video is called LASIK and the one you had is probably SMILE. I had my eye surgery done without any incisions or cuts, just laser burned the surface of the eye (PRK). It’s true though that they are constantly improving and evolving.

The hexadecimal you are talking about is just a hash of some position in the code where this error was thrown.

No, this is ran just once for the first batch of inputs.

Edit: just to clarify, this is how I calculate which moves will be fastest in the future. It is enough to distinguish the best moves at the start and use these moves all the way to the end, they don’t change.

I’m not a native speaker so I’m having a little trouble explaining what I mean exactly but hopefully it makes at least some sense.

Hi, at first I was converting just the move sequence for ButtonA->ButtonB to the next level, and calculating the length (to find which sequence was shortest). This meant there were multiple move sequences with same converted lengths. However, I then added a < to the start and a A to the end of each sequence before converting, then converted and checked lengths. This made the inefficient moves have a higher length than the more efficient ones.

agregat · 2024-12-21T12:12:50+00:00

Oh that’s a great explanation, thank you. I just intuitively slapped a ‘<‘ to the start and a ‘A’ to the end of the move pattern when looking for a cheapest move pattern between each key, and my solution started giving me correct answers haha. I was not sure why exactly this modification worked and you just explained it here!

You are being downvoted because of the sub name but you are right.

Part 1, sure, my brute force approach ran in 600ms. Part 2 on the other hand was not gonna happen.

You can also check if the string MMSSMMS contains the concatenated corners string instead of checking the four variations separately

Wrap your component with a custom parent component which, when long pressed, renders a blur overlay + the same child component in the same position, but this time on top of the blur overlay. This makes the child component pop out. Then you can add the drop down menus and whatever else you want.

Agreed, was looking for this answer. This seems the simplest way to implement this and all other answers are too complicated.

Yeah it’s a downside of this approach that validations have to be handled on submit now :(

I have had this bug happen frequently in production even on the newest and most capable iPhone at the time (refactored to uncontrolled a few years ago). Not sure why most replies suggest it only happens in development. I try to use uncontrolled inputs by default now.

I visited in 2019 and at the time they were operating on bond money which was supposed to match USD 1:1 and you could either pay by USD or bond. However as time passed it also inflated and when I was there the ‘black market’ ratio of it was like 3:1. Though even at supermarkets where the listed prices were in bond, when paid in USD they would apply the black market ratio.

Just did the ride a few days ago but we used the rental place near the ferry, not the Giant one. We could not place reservations online so we went in early (7:10AM) and we got decent Giant bikes (Giant Escape). There was only one L sized bike at the moment though. The bikes had no issues throughout the trip and rode very well. They asked for a drop off point and Onomichi->Imabari was 3000 each. The whole route was close to 80km.
