I confess: I love making Sokoban levels with most or all boxes on goal from start. The challenge for me is to make it necessary to move everything to solve the level. Sometimes I succeed. Sometimes I do not.
However carefully I test and however often I think I made a perfect level it often is the case I did not. One boring reason is I do not test my levels carefully enough before I publish them. Another reason is making a level I test the solution many times on the way and probably get mentally locked on specific series of movements and just do not see other simpler/more complicated solutions.
Influenzed by the above reasons I made the competition “Find The Dead Boxes”. Well it really is not a competition but a call to mail me if you find boxes in my levels not needed to move. The same thing with unneeded floors by the way.
Anian is a regular contributor. So if I do not get a mail from him within a week or two after publishing a level I feel quite safe I found all dead boxes myself.
Sometimes it is worth changing the level for something better. Eg. many of the levels in my collection “It’s All Greek” are remade or completely redesigned several times. Sometimes it is not worth changing anything. Eg. “Circular Challenge 13 – Hearts”. I did not notice it was not necessary to move H9. But I like the design as it is. And I really do not think it is possible making a level with the chosen layout of the boxes where it is necessary to move all the boxes. Prove me wrong if you can.
Most of the time Anian finds a box or two but sometimes my carefully thought out level can be solved without moving A LOT of boxes. So is the case with my recent remake of a level by Sokowind. Anians reduced version of the level:
Level: 睿斗推箱子第17关翻拍2
Author: 风过了无痕(Sokowind)+DrFogh+Anian
Comment: Anian found 9 dead boxes and 2 unnecessary floors
Date: 2019-12-15
My best solutions are pushes 604/128 and moves 555/130. You might notice these solutions both are more than 100 moves longer than the first remade level. You might also notice it is easier find a solution. At least I did. No doubt the reason is you have a zillion less possibilities to make a wrong move.
When Anian finds dead boxes he sends me screenshots like this from YSokoban:
And then I spend some hours figuring out if the level really has a solution.
It always has.
2019-12-06
Came across a level by Sokowind from 2012. Level 250 in the Members Puzzles collection at LetsLogic.com.
Not much of a challenge. Best solution 38/10. And you can reduce the level to 3 boxes and 29 floors.
Decided to make a bit more challenging level.
My best solutions pushes 481/116 and moves 448/130. Both with no need to move 2 boxes.
If you find solutions with even more stationary boxes and/or superfluous floors please let me know.
Did any solver manage to solve the new level? No. So you are on your own 🙂

Making Sokoban levels with everything off goal are easy. You do not need any check to be sure everything has to be moved.
Making Sokoban levels with everything on goal needs a lot of work to be sure everything/most of the boxes have to be moved.
Just the case with CC12 – Spade. When I published the level I knew at least two boxes were just for the look. I suspected there could be more. And right I was. Anian found 5 more boxes not needed to move and 3 floors not needed to to solve the level.
I gave the lower left part of the level a make over and came up with the level below. You have one floor less but you do not need to move I11. I am not sure if there are more dead boxes but I am sure nobody will find 7 in the remade level.
And as often written before: Do not hesitate mailing me if you find dead boxes or unneeded floors. I enjoy the challenge and most of the time I am able to make a better level.

It’s hard to test bigger levels for unneeded floors and dead boxes. Anian found 2 unneeded floors in CC6. You will find the enhanced CC6 in the levelfile for an extra challenge. Didn’t solve it yet myself.
2019-06-29
The original CC6 tired me out. However much I changed it Anian always found a few unnecessary floors and dead boxes.
This revision is flipped upside down. Both the design and the solution.

Once in a while (Every second year or so) somebody asks me for a hint or a solution.
2019-06-16
Making levels I often decide beforehand how I want the solved level to look, usually going for a graphically pleasing look.
With this level I went for a circle. But whatever I did I always ended up with a circle with no need to move anything in the bottom.
I decided I wanted an arc instead 🙂
Constructed more than two years ago. Not yet published and it fits nicely in as Circular Challenge 4.

Anian found a solution for Circular Challenge 6 with no need to move 4 boxes or use 10 floors. Oops. And also found a small change so you need all the room you get(2019-06-29: And this is not true either. Try solving the level without moving D4 and F4). Simply an extra wall at G4. I actually think i tested Anians version constructing the level but obviously didn’t try hard enough. Try Anians version

If you don’t know sokoban.cn you should definitely take a look.
You will find the MF8 competition with two new levels to enjoy on a roughly monthly scedule.
The levels are usually difficult. But if you are an experienced player and you take your time you will hopefully end up as a winner.

The levels often have imaginative and beautiful designs. As an example have a look at the rose above. (I am proud to tell you I actually solved it. Took me some days and not a few grey hairs)
Much to my surprise and gratitude i recently received a mail from Yang Chao, the owner of the site. The MF8 Competition has been held for 10 years and now the MF8 Sokoban Competition Committee has awarded me the 10-year “outstanding sokoban designers”:
Thank you very much. I am honored my levels are enjoyed on the other side of the world.
Maybe I should try to expand Circular Trials 6 to about 100-120 boxes. Might be something for MF8…
Today I will present a much simpler design to you.
Don’t spoil the fun with an autosolver.

Maybe I will make this level bigger one day but for now you will only have 30 boxes. And I even solved the level for you 🙂
I´m quite certain you have to move everything. If not it will be one or maybe two of the marked boxes below.
Don’t hesitate to tell me if you find solutions with no need to use all the floors and/or no need to move all the boxes. By the way my best solution so far is 334/120.
Someone will probably beat that.

Around 2 months ago Florent Diedler released Sokolution v2.03. Boosting the number of solved levels yet another few.
However the best new feature is the ability to solve circular levels. E.g. levels like the one below.

News in Sokoban is often hard to come by. Just now I discovered Sokolution 2.02 was released month ago. At the same time I discovered Sokolution 3.0 just was released. You can download it from Florent Diedlers homepage and read my report here.
If you come across any interesting news in Sokoban please let me know and I will publish it here and/or make appropriate links.
“It’s All Greek” is finished and published. I still hold the lovest score at Letslogic but just at the tip of my nails and guess someone else will hold the record very soon.
In lack of greek letters I found my oldest level worth publishing not published yet. You will not need hours solving it (Sorry. Couldn’t resist)

Before you continue you might enjoy the classical greek letters. Not as Sokoban levels but in their true form:

All good things come to and end. So is the case with “It’s All Greek” . And what is more suitable than the last letter in the ancient greek alphabet is the last published level in the collection.
Actually it also was the first since I published Big Omega 9th of september 2017 nearly one and a half year ago.
Why republish Big Omega? Actually it is a totally revised level. No dead boxes in this version.

The first version of this level published 2 month ago has some serious issues. Most of these have been dealt with here I think. It is no longer possible to avoid using the passageway in the middle of the level and you need to move all the boxes except H4 (My best guess). Enjoy.
Title: It’s All Greek – Theta
Author: DrFogh
Comment: As usual Anian found a hoarde of dead boxes in my first versions of Theta. Now there is no need to move H4 and that’s probably it.

I went skiing so you didn’t get anything last weekend. As a compensation you get two variations of Big Delta. One of the last entries in the collection It’s All Greek.
The level went from Denmark to China a few times and each time Anian found solutions with no need to move some boxes. Six in the first version I think and three in the last.
After the last trip to China I made the levels published here. I haven’t tested the levels extensively but I know you don’t need to move F6 and it might be possible to solve the levels without moving J11. And maybe one box more.
In v1 you can free the marked 2×2 floors at the top. In v2 you can only free the marked 2×1 floors. It might make a difference for the possible solutions but i fear not since you can stove away three boxes at the top in both versions. You probably just need a few extra moves to untangle version 2.
I hope I reduced the number of dead boxes to one or two. But I don’t know.
Give it a try.
