Enjoy Sokoban? Enjoy solving Sokoban puzzles?
This might be a place for you. You will occasionally, hopefully often, find a new level or two here.
And you will find other stuff about Sokoban added if the author finds it worthwhile and finds the time.
If you want to play new levels a good site is Sokobanonline.com.
The presentation of the levels is nice and if you are an author you get your level on the frontpage until somebody else have made new levels.
Only drawback is there is no easy way to download levels to play them in your favorite Sokoban Player.
Most of the time a handful of authors produce levels of good quality.
One of these authors is Kjs722 who made a beautiful circular level named Cosmos 27-104. The level above with the SokobanOnline skin.
I would have loved to make that level for my forthcoming Circular Challenge collection. (Sorry, no planned publishing date. Probably 2020 or 2021.)
But I could still experiment with reduction and expansion of Kjs722’s design and ended up with the above suite.
Kjs722’s title refers to best moves and pushes. I will not err on that but just name my levels Kjs722-1, Kjs722-3 and Kjs722-4. And I left Kjs722-5 and higher for you to create.
You can play Cosmos 27-104 at SokobanOnline.com and download the rest of the levels here at Sokoban.dk.
Maybe you were a member of the Yahoo Sokoban mailgroup “You like Sokoban? Interested in puzzles? Here!”.
The group was created 1999 and has been active for 20 years. More than 1000 members. (No doubt a lot of these inactive).
Yahoo changed its group services and the Yahoo Sokoban group have been inactive since 24th of december 2019
Don’t panic. A Sokoban group has been created at groups.io and this is certainly the place to go if you want to discuss Sokoban or maybe just want to get help for a difficult level.
Actually the group has been more active for the last two months than the Yahoo group has been for the last 2 years.
E.g. you will find an interesting discussion about screen.77 in the Original Extra collection. I wrote about this back in 2016 but it seems I didn’t quite get it right. You can read the discussion here
The groups.io interface is easy to learn. And you don’t even need to learn it since you get (If you want to) everything in your mailbox and can answer mails without ever going to Sokoban@groups.io’s homepage.
You will also find a new Sokoban group on Facebook. Actually created before the group at groups.io.
However great this initiative is I think the Sokoban group at groups.io wil be the new forum for Sokoban entusiasts.
First thing is the discussions are happening at groups.io.
And you are totally free from the usual Facebook sludge.

Comment: You have to solve the letters from left to right. Tell me if anything else is possible. email@example.com
Skin: Boxworld by Jeng Jong Liang
I didn’t publish this level before and you can’t download it from here.
You need to go to The Download Page where you can download my new collection Original 3.
If you are a regular user here at Sokoban.dk you have seen most of the levels before, but not all.
If you want my comments (boring or thrilling. Who knows) for the levels download Original 3 from Sokoban.dk
If you only want to compete for a lowscore you will find Original 3 at LetsLogic.com
My last Mercedes wasn’t much better. Anian solved the level without moving O5. Disappointing to say the least. A new version with this possibility blocked is coming up. While you wait for that try your solving skills on this:
Title: Circular Challenge 17 – Lazy Level
Comment: My best moves solution 149/52, no need to move 3 boxes, no need to use one floor.
My best pushes solution 177/50, no need to move one box. Lazy Level? I have no intention trying to change this level.

Tired of Mercedes? Then buy a Toyota. Makes nice cars too 🙂
(And I will publish some brand new levels in a not far future.)
Here I struggle to bring my Mercedes beyond the prototype stadium. Now you can’t solve the level by going left at the top. Actually I made that impossible. And you need to do a little more boxmoving to get the bottom right.
Title: Circular Challenge 20 Mercedes Rev 2
Comment: My best solution has 5 dead boxes and 1 unneeded floor. Probably possible to find more.
Skin: YSokoban by George Petrov
Guess the Mercedes is not build yet… Read the last development
Forget about the first version. This one is better.
Title: Circular Challenge 20 – Mercedes Rev
Comment: Anian found 21 dead boxes in the first version. Here it is not 21 but it certainly is not 0 either.
Once a while (About once a year) I am asked how to develop a Sokoban level.
I wrote a story creating the level below.
Being a little lazy recently with no updates since new year. But here is a new level at least.

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
Comment: Anian found 9 dead boxes and 2 unnecessary floors
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.
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 🙂
Comment: Remade level at the right if you did not notice.

Been a while. Holiday, work and such.
Hope you have as much fun solving this level as I had creating it.
Title: Circular Challenge 16 – Rod of Asclepius
Comment: Workrelated 🙂 (Dr stands for doctor)

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.
Title: Circular Challenge 12 – New Spade
Comment: I know you do not need to move I11. Any more?
Title: Circular Challenge 12 – Spade
Comment: No need to move G3 and F4

For some forgotten reason I had a look at level 87
(Attention Virus) in the collection Sokostation by Ghislain Martin and
decided the level was in for a brush up. You would probably not notice if I didn’t mention it.

You can make several variations stoning boxes in this layout. You will find some of these in the levelfile.

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.
