Talk about the standard before writing. Although the word “difficulty” was added after the word “ceiling” in the question, I think it would be better to get the answer without adding it. Because the difficulty of evaluating hardcore scripts is one of the most important factors, pay attention! It is by no means the only factor. For example, if it is purely based on the volume of the pile, or a lot of cases that are not closely connected, it may be more difficult than reducing one case/a certain volume. But when it comes to playability, it might be better to cut some of it. To say this is to criticize many hard-core reduction scripts that don’t know how to “do subtraction”. On the one hand, in order to be able to write a few more, on the other hand, because the top-level inflection and the top-level beneficiation difficulty are the former’s dimensionality reduction blow to the latter, I separate the inflection and the benevolence and write each one I’ve played. The top three in this book. Changing the ceiling TOP1 “the past” first talk about the background: I have played 200+ books, mainly playing hard-core reasoning, and generally go to the famous books to play, so far no hard-core script can match. All players who have played the past also put it in the hardcore first echelon, most of them ranked first. Let’s talk about the content (no spoilers): 6-8 hours or so, 6 hours should be enough for a tighter rhythm. The link includes ice-breaking exchanges, multiple murder cases with tactics, narrative and trick restoration and reversal story restoration. The whole script is well-designed and the difficulty increases exponentially with the links to fullness. The only point of deduction is that some characters in certain links are marginal, others are perfect. Final advice: Players who do not have a perfect restoration or a basic restoration of “Annual Rings” should be cautious in entering the game. TOP2 “Archive-Glass House” first talk about the background: the boxed hard core ceiling, even if the city limit and exclusiveness are included, I can rank second here. Except for a few players who were forcibly disgusted by the suspected plagiarism in the first two murder cases with tactics, the players who played around basically ranked it in the top of the box. There is also one who thinks it is the ceiling. My personal opinion on plagiarism is this. First of all, I read the original work. It is actually not the same. It has been revised to a certain extent. Even if I read it, I might not think it was this. Secondly, 99% of players I think they have never read the original, so playing does not affect the experience. In the end, when our car was playing, there was no way at all. The timeline alone caught the killer. In a sense, the place that represents the “suspected plagiarism” is actually not that important. You can rest assured to try it. Let’s talk about the content: 4-5 hours, perfect script structure (more than the past, the hard core I have played so far is the most perfect structure, can use such a short time to achieve the ultimate difficulty + reversal, although the sparrow is small and complete), the core trick Part of it is extremely difficult, not like the restoration of the piecemeal story, but a very compact and large timeline. The first two benign dishes and the final story restoration are also very exciting. Final recommendation: the same thing as in the past. TOP3 “Zhou Gong’s Travel Notes” first talk about the background: in fact, when facing the word “hardcore ceiling”, I think of “The Past” in the limited school and the “Glass House” in the box, and my brain is blank. There are many that I think are good. If you look closely, they are all in the original style, and it is impossible to head-on with the change list in terms of difficulty. In the end, Zhou Gong, who has a higher voice among the old players around me, came into my eyes. I often heard them rank “The Past” and “Zhou Gong” as well as the “Sage’s Stone” I haven’t played yet in the top three, but I Personally, I think it’s still difficult to tie in with “Once Upon a Time”, and the difficulty is one level worse. But it is true that there is no other person who is qualified to grab it, so put it here. Let’s talk about the content: 6-8 hours, it can be solved within 6 hours. It is very different from the first two top ceilings. The difficulty of the first four cases of Zhou Gong is decreasing, and in the end there is a climax part that should be very difficult. Due to the simple method and the fact that there will be such a long time ago. Because of the link, the difficulty is not so big, so you will feel that this book is easier to play, and in the end, you thought it was very difficult, but you also quickly found the answer. There is a feeling of fist hitting cotton. I think the structural design is above average. The first four cases make people feel a little stitched and there are only two suspects in each case, which makes it difficult for you to make a mistake. However, the first two tricks are still good, but unfortunately it is too much of a player’s configuration. If he can’t work, it is likely that everyone will not work. Final advice: As long as you are a hardcore enthusiast, you can try to play, even if you don’t understand the disc, you can fool the murderer, which is very experience (no). Codewords are tired. When I finish playing with Axe Off tomorrow, I will send out the top three in this case. Many other answers mentioned the prestigious Off and 713. I happen to be playing this week and next weekend. I will take a look at this when the time comes. Can the two squeeze into the top three of my book, hardcore, there are more books with good book than with change, and the competition is still fierce.
