This type of puzzles are often very difficult. The explanation of this fact may be this: with all the boxes placed, the free spaces are minimal, so that the difficulty is maximum.
In this post I have made a selection of some "fix one", and as usual I have tried are represented different styles, authors and difficulties. Comments and suggestions are accepted.
In small "fix one" four authors stand out: Sven Egevad, Aymeric du Peloux (collections Nabokosmos and Picokosmos), Evgeny Grigoriev (collections GrigrSpecial and GrigrComet) and Thomas Reinke. And of course, gyjgw, author of excellent remodels.
Criteria:
- All boxes are placed, except one.
- Maximum 60 boxes. So, this selection is limited to the puzzles of medium and small size, and leave the big levels for another occasion... :P
Note.- In other "Sokoban lessons" there are numerous levels "fix one" selected, that I will not repeat here.
In another post I will make a selection of levels "many-in-goal" (according to the terminology of Sven Egevad): all the boxes are placed except a minimum percentage.

Title: Sokoban Perfect #288 b
First release of the original level: Soukoban (1985, Sega) #69, then in Sokoban Perfect (1989)
Date: December 1985. Remodel: 2005.7.4
Difficulty: 6.5
Best moves/pushes: 273/100
At the time of Thinking Rabbit was invented practically everything concerning to Sokoban, and also appeared the first puzzles "fix one". This level of unknown author was one of the first "many-in-goal" (the original version has 45 boxes, 2 of them unplaced). I posted a remodel of gyjgw, slightly more difficult.
Question: the 3 "signs" of this puzzle, do they have any meaning, or are simple drawings?
As a curiosity, these were the first levels "many-in-goal" of Thinking Rabbit:
- Siji Nishikawa, Soukoban (1985, Sega) #68 (Sokoban Perfect #303)
- unknown, id. #69 (Sokoban Perfect #288)
- id. #74 (Sokoban Perfect #84 and #305, Masaki Ishino; Sokoban Revenge #279, Kazuo Fukushima)
- id. #88 (Sokoban Perfect #215)
- Yoshio Sakae, Sokoban Perfect (1989) #250, and Sokoban Revenge (1991) #212
- Yoshio Sakae, id. #251
- Yoshio Sakae, id. #263

Two "diamonds", with the unplaced box and goal in the center of diamonds, respectively. York Shen made up to seven remodels of this level, but none of them is "fix one".

The first diamond "fix one" was published in Soukoban (1985, Sega) #88 (then in Sokoban Perfect #215), by an unknown author, with the goal in the center of the diamond and the unplaced box on the outside. Sokoban Revenge #228, of Takahiro Suzushima, seems a remodel of Sokoban Perfect #215, but with the unplaced box in the center of the diamond, which increases significantly the difficulty. Here I post this remodel of Hir, slightly harder than Sokoban Revenge #228.

"Genten kaiki" (原点回帰) = "Basics" (according to Google). Elaborate and difficult "fix one". A level-adventure in which the player have to tour all the rooms of the map and practically move all the boxes. Perhaps one of the best puzzles in this style.

Hard! Before you begin to move all the boxes (which is what I always do... xD ), I recommend thinking about how is built the "ç". My rating: 8.

Excellent! This is one of my favorite "compact" in this selection. We have take out all the boxes, and then to place them again :P ...
"Salto" (cальто) = "somersault": "an acrobatic exercise in which a person's body revolves 360° with feet passing over the head" (from Wikipedia). Curiously, the voice "cальто" derives from the latin "saltus", so that both in Russian and Italian, Spanish or Portuguese we use the same word "salto".

This puzzle could be called "the magic square", and is part of a series of several very similar levels. Recalls the famous "squares" of Sven Egevad (see SE 134 et seq.), but this series is quite more synthetic and difficult.

Typical diamond. It is not particularly difficult, but it's nice. It is probably a remodel of Sokoban Perfect #215 (with box unplaced in the center of the diamond), or perhaps an extension of Sokoban Revenge #228.
I have taken the liberty to modify its visual aspect as in Sokoban Perfect #215, with double outer wall :)
