Sasquatch Challenge


David W. Skinner (Grandview, Washington, USA) is one of the most famous authors of Sokoban. This well-deserved fame is due, largely, to its spectacular symmetrical puzzles, some of big size; and, secondly, to its long dedication to Sokoban during more than 13 years, since January 1999.

The 600 puzzles of the XII sets of Sasquatch can be grouped into these four major types:


- symmetrical levels                               278 levels
- storage                                           74   "
- maze (only in the first sets I-IV)                 9   "

- small levels (less than 10 boxes) and other      239   "
 
In Sasquatch Challenge I have selected my 80 favorite levels. With few exceptions, they are of medium difficulty and fun to solve. I have chosen these levels:

Sasquatch I: 9, 12, 19, 27, 29, 46, 48, 49          = 8 levels
II:     5, 7, 10, 23, 29, 31, 38, 42                = 8   "
III:    3, 4, 22, 26, 28, 33, 34, 43                = 8 
  "
IV:    2, 8, 9, 20, 25, 29, 30, 31, 36, 41, 44, 49  = 12 
"
V:     10, 25, 27, 31, 46                           = 5   "
VI:    10, 11, 31, 35, 42, 43, 49                   = 7   "
VII:   3, 23, 27, 36, 43, 44, 47, 48                = 8   "
VIII:  36, 41, 48                                   = 3   "
IX:    13, 14, 16, 31, 36, 37, 39, 47               = 8   "
X:     23, 26, 30, 31, 37, 49                       = 6   "
XI:    11, 12, 23, 31, 45, 46, 50                   = 7   "


I add also 33 remodels - usually hard - of York Shen, gyjgw, GRIGoRusha, stopheart, zhenying, Přemysl Zíka, and myself.

Sasquatch Challenge (80 levels + 33 remodels)

Sokoban lessons - Lines (5-8 boxes)

The "line" is one of the figures most simple and classic of Sokoban. In this post I publish a selection of my favorite "lines", between 5 and 8 boxes.

In some puzzles I accept one or even two boxes of hindrance, but always independent of the "line".

This type of puzzle is known as "Fibo" (by the Italian mathematician of the 12th century, Fibonacci, introducer in Europe of the "Fibonacci sequence"). It is one of the most famous puzzles of Sokoban. As in the Fibonacci sequence, each box which you add increases exponentially the number of moves/pushes needed to solve it: see "Theoretical analysis on Picokosmos 17" by David Holland (article published in the old website of Aymeric du Peloux). Many versions of this puzzle have been made. See also Picokosmos #12 (Hanoi).

Sokoban lessons - Many-in-goal

According to the terminology used by Sven Egevad, "many-in-goal" is the puzzle in which all the boxes are placed except a minimum percentage.

In this post, the conditions for which a puzzle is considered as "many-in-goal", are these:


- Maximum size of the puzzles: 80 boxes. I reserve the puzzles of larger size for another post :P
- Maximum number of boxes unplaced: 10 %. Example, for a puzzle of 60 boxes, maximum number of boxes unplaced = 6. Anyway, this last criterion is flexible in some cases.

The structure of this curious puzzle is very original: two diamonds connected by top and bottom. I don't know why, remember me two Oriental lanterns...

The first version of this puzzle was published in Sokoban (1985, Sega) #74, then in Sokoban Perfect (1989) #84. Inexplicably, this first version is very easy, and perhaps why two remodels were made: the first, in the same collection Sokoban Perfect #305 (by Masaki Ishino), and then another remodel in Sokoban Revenge #279 (by Kazuo Fukushima).

Then I publish the three remodels which in my opinion are the best of this classic puzzle.

"Orimaze" is an acronym for "oriented maze". This difficult type of puzzles was created by Dries De Clercq. I recommend starting by "orimazes" simpler, to familiarize yourself with the technique of resolution (see "Orimaze" collection). Comment from Dries De Clercq on its website: "This is a 5x5 orimaze with a hole in the middle. This mill turns a lot!"

On the right side, from top to bottom it reads "8 年" ("8 years"). This nice puzzle was designed to commemorate the eight years of the Chinese forum FM8. Very fun to solve!

Fantastic puzzle! The two Chinese characters 生命 mean "life". This puzzle was posted after copying the lyrics of "生命之曲" ("Song of Life", October 1988) of the "cantopop" George Lam. In YouTube: 生命之曲.

电 = "electricity" (or perhaps "lightning"...). Although this remodel has 7 unplaced boxes, I include it also in this selection.

A side B side. The double life (2010) is a film from the Chinese director Ning Ying. As the previous one, is equally interesting and fun to solve.

Double stairs! Nice and curious puzzle.


Next, I publish four puzzles that I selected from the collection "Secundus gradus ad Olympo". This four puzzles are - in my opinion - exceptional and very nice to solve. Přemysl Zíka is an author of other "many-in-goal": I suggest to see the list "other recommended puzzles" at the end of this page.
