Sokoban lessons - Squares and small diamonds

The square (8 or 9 boxes) is one of the most nice figures, and one of my favorites. Monry, Kenyam, GRIGoRusha, François Marques, Thomas Reinke, and especially Kevin B. Reilly, is the authors who more have dealt with this figure.

In this post I made a selection of the most interesting and beautiful squares. I also include a selection of "small diamonds" (= square rotated 45°). Condition: the puzzles may have other goals, but independent of the figure, and a maximum of three goals.

Author: monry
Title: monry-light #114
Date: 1999.3.22
Difficulty: 7
Best moves/pushes: 477/92

Remodel of previous monry-light #102. It is the last puzzle in the monry-light series, and perhaps the best of the "squares" of monry, with a difficult storage. Note in the upper-right corner the "mechanism" with a double room and a captive box, that allows the passage from N-S and S-N, changing conveniently the position of the captive box (up/down in the double room).

Monry has a lot of squares. See especially monry-light #6 (good), #11, #26, #34, #38, #43, #53, #102, #104, #106 (the beginning is very weak, but the second part is very good); and FirstStep 801, 803.

Amazing! You will need 279/87 moves to place the first box. Very similar to the previous fun level #117 ("Dreams"), but I think this level #126 is a bit more difficult.

See also Grigr2002 #34, GrigrSpecial #8 (hard), GrigrSun #6 "Opened Heart" (extremely hard,

Sokoban lessons - Storage: Two rows

The golden age of storage puzzles is that of Thinking Rabbit. In the collections of Thinking Rabbit, virtually we found all the possible problems of storage. Thus, it is not surprising that of the 21 puzzles chosen here, 7 are of Thinking Rabbit. And, in my opinion, between the creators who collaborated with Thinking Rabbit, two stand out: Hidemitsu Kobayashi and Yoshio Sakae.

"Two rows" (or columns) is a special case of storage, which has a particular interest. In this post I publish some of the puzzles "two rows" that I like most. With these characteristics:

- At least 10 goals (5+5 goals). I reserve the "eights" (4+4) for a specific post.
- The storage area must be surrounded by walls. Maximum number of entrances that connect the storage area with the rest of the puzzle = 30 %. The
entrances must be non adjacent (I have done some exception to the latter condition).
- There may be other areas of storage in the puzzle, but the theme "two rows" has to be the main.

You can download all puzzles (except commercial) here:
 




Author: unknown (Thinking Rabbit) + York Shen
Title: Sokoban Perfect #284 a (arr.)
Comment: added 1 box
First release of the original level: 倉庫番2 (Sokoban 2; Thinking Rabbit, 1984) #43, and then Soko-Ban (Spectrum HoloByte, 1988) #29
Date: February 1984. Remodel: c. 2003
Difficulty: 6.5
Best moves/pushes: 681/213


This is the first level "two rows" of Sokoban and also the first in which they are used unequivocally rooms with sliding boxes. There are 29 remodels of this puzzle (see all versions here), but I choose this version of York Shen, with a box more, which greatly increases the difficulty. I've slightly arranged the map (upper-left corner). The arrangement is also valid for the original level :)

About the rooms with sliding boxes
The difficulty of this level is that it is possible to circulate from North to South, but not from the South to the North: the sliding boxes in the rooms at the four corners (marked in red, see image below), obstruct the passage of S-N. To move from South to North there is no other way to go through the storage area... :(   Thus, to solve this level, we must first remove the 2 sliding boxes (marked in red) on one side of the level (in this case, we will remove the 2 boxes on the left side). Conclusion: in the levels with rooms and sliding boxes, first need to study very well the circulation pathways.

First release of the original level: 倉庫番2 (Sokoban 2; Thinking Rabbit, 1984) #44
Date:
February 1984. Remodel: c. 2003
Difficulty: 6.5
Best moves/pushes: 4049/1082


"Two rows" in right angle. The unknown author of this excellent level, might be the same as Sokoban Perfect #284 (= Original #29, see above the previous puzzle), because both were published consecutively in Sokoban 2 (1984), levels #43 and #44 respectively. The version of York Shen (+2 boxes) is of similar difficulty to the original.

Title: Sokoban Perfect #192 a
Comment: added 1 box
Date: 1989. Remodel: c. 2003
Difficulty: 6.5
Best moves/pushes: 2073/620

York Shen added a box, which significantly increases the difficulty. See also of Hidemitsu Kobayashi: Sokoban Perfect #253 (below), and Sokoban Revenge #264.

Title: Sokoban Perfect #217 b
Comment:
stoned many floors - J.D.
added 4 boxes, some changes - stopheart
Date: 1989. Remodel: 2011.8.25, and 2011.9.1
Difficulty: 7
Best moves/pushes: 1459/363

The version of stopheart, with 4 more boxes, is rather more difficult than the original. Stopheart has made some changes in the structure, especially at the top, where he has built a double room with a captive box. This funny "mechanism" allows the passage in both directions, N-S and S-N, conveniently changing the position of the box (up/down in the double room). See also this mechanism in the level of Vipul Patel, below (Sokodeal #55).




Author: Hidemitsu Kobayashi
Title: Sokoban Perfect #253
Date: 1989
Difficulty: 6.5
Best moves/pushes: 1648/673


This level has two major difficulties: 1) take out the first box of the right area... 2) but the biggest difficulty is how to place the boxes in the cargo area (left). Warning: small trap in the storage area (I bet you have to repeat this level...). There is no remodels of this level, and the reason is simple: is not possible to add a single box or wall. 




Author: Masaki Ishino + York Shen
Title: Sokoban Perfect #306 b-2
Date: 1989. Remodel: c. 2003
Difficulty: 7.5
Best moves/pushes: 8266/1900


It is the last level of Sokoban Perfect and one of the most difficult and arduous to solve in this collection. The version of York Shen change of place 9 goals, which obliges to use storage area for storing some boxes on an interim basis, and forced to move the boxes by two rows of the storage area (exits out a box at the bottom, comes inside another box above).




Author: Yoshio Sakae
Title: Sokoban Revenge #145
