Sokoban lessons - Six

As a curiosity, the first "six" in the history of Sokoban is the #1 puzzle from the "Original" collection...

The first "six": 倉庫番 (Sokoban, Thinking Rabbit, 1982, for FM-7), Level 1

In general, the "six" is a figure that can pose many difficulty. First, by the number of boxes: from 5 boxes is already possible to find very difficult puzzles. Secondly, by the enclosure of the goals between walls, which raises typical problems of storage: what box must be put first, which second... and so forth six boxes.

These are my favourite "six", in chronological order. You can download all puzzles here:

This puzzle could be entitled "The magic box". It poses a simple problem of storage (and the use of spaces in the rooms), but it is a masterpiece in its simplicity.

Incredible miniature! Truly, we must dance a "waltz" of moves to find a solution. Sustained difficulty up to almost the last box.

Title: Grig2002 #102 Wake up
Date: March 2002
Website: grigr.narod.ru/
Difficulty: 6.5
Best moves/pushes: 398/98

One of my favorite "six". It is a very nice puzzle to solve and not too difficult. Structure with the "store room" in the central area and circulation around. The best and the most surprising of this puzzle is that no box is placed easy: all boxes, from the first to the last, have difficulty... This gives the measure of the quality of a good puzzle!

A "cross-six", a "six" within a cross-shaped structure: it's impossible more difficulty. See other similar "cross-six", also very good: monry-light #78 and #108; Hirohiko Nakamiya, Monster Sokoban 8-1; Kenyam #42; Kevin B. Reilly #1369 and #1951; and Thomas Reinke, Anomaly 2 #22.

Fantastic "mini six"! With a simple structure of one room and "store room", get ready to go round and round... My optimized solution: 264/48. No comment... However, it's a puzzle very nice to solve, and despite being so compact it's not especially hard.

Author: Edwin Abbot
Title: Flatland #10
Date: December 2009
Difficulty: 7
Best moves/pushes: 273/86

Puzzle that you previously need to be solved almost mentally, because it is necessary to analyze very well in what order the boxes are to be placed in the store room: what box comes first, which is the second, etc. Typical puzzle of this excellent and strange "Flatland" collection... By the way, the author of this collection seems to be using as a pseudonym the name of Edwin Abbott (1838-1926), english mathematician and author of "Flatland: A Romance of Many Dimensions" (1884)...

Přemysl Zíka

Přemysl Zíka is a new Czech author who last October published a collection of 168 puzzles. The collection seems to have a systematic intention, exploring the constructive possibilities of Sokoban, from puzzles with only 2 or 3 boxes, until other very complex puzzles. Přemysl Zíka seems to be interested in a special way by the structure of the puzzles. There are very beautiful and frankly interesting puzzles.

Especially out-standing is the last puzzle of the collection (pz233, see image), of high difficulty (difficulty rating: 9). To solve it is necessary to study very well how the boxes are loaded in the goals area, and at the same time pay a lot of attention in the movement of the boxes around the store room, taking maximum advantage of all the spaces.

You can download Přemysl Zíka's collections on his website.

Přemysl email is very interesting. I reproduce a few paragraphs:

Dear Jordi Domenech,

I greatly appreciate your positive assessment and collection of puzzles you like. Small or lighter levels or puns I composed for my daughters (8 and 5 years). Emerged gradually, with years of breaks, sometimes from 1990 to 2011 and the first time published in the autumn of 2011. Since then I have created only about 10 levels.

My consent to disclosure of collection of 168 (+9 others) puzzles, of course, I give you, it's an honor for me. I'll be happy if they find puzzles response among the other solvers. Your website and your puzzles known, I've a number of them solved.

If you decide to put it one my riddle (for example 233) directly to the your website alongside such greats as ZiKo, Aymeric du Peloux and others, it will be the highest award for me.

I send another levels (169-177).

SokoStation variations

A new collection. Click on the image or title to download

SokoStation variations Authors: Ghislain Martin and Jordi Domènech January 2012. 95 puzzles This collection brings together 95 "variations" of the puzzles of Ghislain Martin, most of them belonging to his fantastic collection "SokoStation". Some of these "variations" are very difficult. I hesitated if include them in this selection, because all that is gained in difficulty, is lost in fun. Ghislain Martin puzzles are very clever and very fun, however, these "variations" are at risk of being difficult and boring. I recommend this: If you can't solve a puzzle, leave it for last, and try to solve the following. Enjoy!

The Chinese forum MF8 meets 8 years. To commemorate it, "gyjgw" has designed the puzzle of 30th Sokoban Competition (from top to bottom it reads "8 years"). It's a characteristic puzzle "many in goal" of "gyjgw", but of medium difficulty (not too hard) and very nice to solve.

Finis Europa!

Finis Europa! Europe has ceased to exist. Thanks to a Nazi gang of irresponsible (sic), Europe is just a name on the map.

About this abortion of "Destabilization Pact" -or select Club of top countries- has no future, if the monster comes to birth. Because what is born of the imposition and brutality can only be maintained through the imposition and more brutality. I don't think this is the dream of any country.

With respect to the South, we will be poor again, but not barbarians. From Spain, I am glad not to participate in this select Club of neo-barbarians, that in a few months have achieved the great feat of destroying Europe ... and wait.

_______

Finis Europa! Europa ha dejado de existir. Gracias a una pandilla de nazis irresponsables (sic), Europa ya es sólo un nombre en el mapa.

Respecto a este engendro de "Pacto de Desestabilización" -o selecto Club de países de primera- tiene los días contados, si es que este monstruo llega a nacer. Porque lo que ha nacido de la imposición y de la brutalidad sólo puede mantenerse por medio de la imposición y más brutalidad. Dudo que éste sea el sueño de ningún país.

Por lo que respecta al Sur, seremos otra vez pobres, pero no bárbaros. Como español, me felicito de no participar en este selecto Club de neobárbaros, que en pocos meses ha conseguido la gran hazaña de hundir y destruir Europa... y espera.

Sokoban lessons - Two boxes

Classic "T". This same theme is found in two previous puzzles by David W. Skinner, Microban #1 (2000) and François Marques, Novoban #15 (2001). The three puzzles are almost identical, but I prefer this to the initial position of the boxes and connected goals.
