Sokoban lessons - Sokoban pilgrimage

The last level of Sokoban Revenge (#306), by Yoshio Sakae, is entitled 倉庫番の巡礼, "Sokoban pilgrimage" (see puzzle below). This is a structure of several columns of 2 floors of width, and occupied by boxes, arranged alternately. The difficulty of this puzzle is that to place a box is necessary move alternately all the other boxes.

This post is dedicated to this typology of puzzles. These are the conditions:

- Two or more rows (or columns) adjacent, connected each other by one or more non-adjacent passages. The rows/columns can also be connected forming various structures: quadrilateral, "cross", "snail", "windmill"...
- The rows (or columns) have a maximum width 2 floors, and are occupied almost entirely by boxes, usually distributed alternately. The goals can be placed in storage areas, but are usually distributed alternately in the rows/columns, on the opposite walls to boxes.

With a few exceptions, I do not include small puzzles (up to 6 boxes), because many have already been published in other "Sokoban lessons".


You can download all puzzles (except commercial) here:




Author: Thinking Rabbit
Title: Original #23
Date: 1988
First version: Sokoban 2 (1984) #13; later added in Sokoban Perfect (1989) #154. New version in Sokoban Revenge (1991) #72 (Takahiro Suzushima).
Difficulty: 5
Best moves/pushes: 1055/454


This is the first puzzle that presents an embryonic structure of "Sokoban pilgrimage". Three central columns and storage area on one end; in the two areas on the right is possible to change the direction of the boxes.


Note that the 9 red boxes have to change to the opposite wall. To do this, we need to move these boxes to the two areas on the right, where it is possible to change the direction of boxes, and then bring them up to the storage area.

Basically, the biggest problem with this type of puzzles is to find these areas where it is possible to change the boxes to the opposite wall. Frequently, locate these areas is not so evident as in this puzzle.

Title: Sokoban Revenge #208 パバーヌ (Pavane)
Date: 1991. First publication: Sokoban Deluxe (1990) #5-B
Difficulty: 4.5
Best moves/pushes: 251/84


Double rotation of the boxes: the boxes on the left rotate clockwise, and the boxes to the right in the reverse direction. Hence perhaps the name of "Pavane", the slow processional dance common in Europe during the 16th century. This nice theme has also been treated, among others, by Hirohiko Nakamiya, Joy levels #1; David W. Skinner, Sasquatch IV #9, and Microban III #8; Přemysl Zíka, Primus gradus ad Olympo #52...




Author: Yoshio Sakae
Title: Sokoban Revenge #145 ゲンコツ (Fist)
Date: 1991
Difficulty: 6.5
Best moves/pushes: 577/160


Fantastic puzzle of storage, already published (see "Storage: Two rows"), but it is imperative to repeat here.




Author: Yoshio Sakae
Title: Sokoban Revenge #146 扉の向こう側 (The other side of the door)
Date: 1991
Difficulty: 6
Best moves/pushes: 600/160


Another exceptional puzzle, previously published in "Big lines". This puzzle, along with the above, I think that they can be considered two of the best puzzles of Yoshio Sakae.




Author: Yoshio Sakae
Title: Sokoban Revenge #206 カルナバル (Carnival)
Date: 1991
Difficulty: 6
Best moves/pushes: 2258/682


Excellent rotatory puzzle, within a snail-shaped structure.




Author: Yoshio Sakae
Title: Sokoban Revenge #306 倉庫番の巡礼 (Sokoban pilgrimage)
Date: 1991
Difficulty: 6.5
Best moves/pushes: 11011/5929 (Johannes Steinmüller)


Along with the Nakamiya and 20603 (see below), this is one of the most classic puzzles in this style.

Note that all boxes have to change to the opposite wall. The area for the change of direction of the boxes is the small "tooth" of the top end right.

See a reduced version (perhaps also of Yoshio Sakae) in Ultimate Sokoban (1996) Stage 2 #4-6. See also this mini version of Skinner:

Exceptional rotatory puzzle, within a windmill-shaped structure. It is one of the puzzles more classic in the "pilgrimage style", along with 20603 (see below). How to change the boxes to the opposite wall? You can practice with these two reduced versions, the first of the own Nakamiya:

Laborious and difficult "Sokoban pilgrimage", which combines rows with two columns. I recommend trying to first solve the reduced version, also of 20603:

Sven Egevad has several levels inspired by the "mini" version of "Long march" (see SE 1297 and following), but I prefer these two small puzzles (see also below SE 1417).

In fact, it's a puzzle of storage, but it is not easy to see how to load the columns. Very tight.

Title: MasterVIP #40 Big march variation 5
Date: June 2008
Difficulty: 7.5
Best moves/pushes: 87035/41088 (MikeArcher)


It's raining? Then, this is the perfect puzzle. I don't know how many hours it takes to solve this maxi-pilgrimage, but probably more than 3 hours... In MasterVIP there are 8 variations of "Long march", quite similar: I choose this "variation 5", since it is perhaps the most entertaining. The non-optimized result is about 200,000 moves...

Incredible! In my opinion, is one of the best puzzles of this set... You have to do a lot of maneuvers in the top row to place the first box...

A1master


The first collection of A1master "1,000,001 candlelights" (100 levels) is a hotchpotch. There are mixed original puzzles of the author, along with versions of other authors; very easy puzzles, almost for kids (#12, 13, 46...), along with other highly difficult and technical... This hodgepodge produces a certain sensation of disorder. However, there are some puzzles surprisingly very good. My impression is that A1master has learned in a few months what others we have taken years to learn.

You can download all collections of A1master in Let's Logic, here:




Next I publish five of the puzzles that I have liked more. They are of small size and medium difficulty. It is a delight to solve these puzzles!...  I hope that A1master build many more. Enjoy!
