In Let's Logic, Tiaoa has posted a series of entertaining and imaginative "snakes". So, I asked myself: what is the best "snake" of Sokoban? And, right away, I thought in this "Cobra" by Marko Dzekic. Without doubt, is one of the most original and beautiful "snakes" that I know. I posting it here because, in addition, I believe that is not well known to fans. It was posted in 2011 in the Chinese forum MF8.

Hint: It is a "snake" very "logical" ... You don't push all the boxes!

If one day I have time, maybe even make a selection of the most beautiful "snakes", to add it to "Sokoban lessons".



Přemysl Zíka has sent me this difficult remodel with two more boxes (!) ...

Comment:

   - In first step I added 2 boxes (meanwhile on my small working version: gyjgw and anian used to fine-adjust one goal and minor changes); difficulty of this my 1st version: 9.3 (original difficulty from Marko Dzekic is about 7) [note: in my small working version I have checked only the solutions with 2 boxes extra].
   - In second step, I moved 1 goal to left down. Then I've changed the position of goals in the middle room (I'm inspired by gyjgw + anian - and I thank them for that), closed from both sides; difficulty of this 2nd version and concurrently my final version: 9.5.

The main scope of work of a sokoban player (and actually a "joke" of this level) is in the big "S"... (...my little help for sokoban players: be very careful you move many boxes, advantage is each space - even the slightest - even in the middle of the floor). Second version are "little changes", that they in the last version a little increase the difficulty, interest, attractiveness and popularity... (...my little help for sokoban players: middle room you must closed to the end of the solution).

My first ... and also at the same time solution: 98261/14307 (...crazy).

A prerequisite after the optimization: 40000 moves (please send me the solution - thank you).- P.Z.
