Any more untouched ?
Touch what you want: My best moves 425/136 and pushes 505/92
3 untouched: 439/102 and 505/92
It seems best pushes most of the time is best or equal with maximum untouched boxes. Will it always be so ?

Skin: Ambrosia by Quote Pilgrim
My first optimized solution was 715 pushes with 22 untouched boxes and 5 untouched floors. It is not necessary to move the box at P9.
JSoko found 5 more untouched boxes.Optimizing this solution moves/pushes 604/172 and pushes/moves 1010/168. Surprisingly JSoko moved P9 and this reduced my best solution by more than 100 moves.
Tell me if you find solutions with more untouched boxes/floors.
Update on Lexus New: 油纸成伞 found a solution with 14(6 obvious) untouched boxes. So my hourlong efforts to improve the level only meant a reduction of one untouched box.
2025-10-26
油纸成伞 found a solution for Lexus with 9 untouched boxes (excluded the 6 fixed boxes).
I made a small change to Lexus as marked.
JSoko found 4 untouched boxes. More ?

Pushes 561/179. Moves 560/203
油纸成伞 sent me a solution for Citroen with 8 untouched boxes and 12 untouched floors:
If you solve Citroen using some qualified guessing and just focus on getting the level solved you will probably never reach this solution.
Afterwards you can use the optimizer in YASC and get a shorter solution. And you can use the optimizer in JSoko to look for untouched boxes and untouched floors.
But the optimizers work with the given solution and don’t find other solutions to optimize.
I optimized 油纸成伞’s solution with YASC: Moves 543/190 and pushes 575/176.
JSoko found no more untouched boxes.

Comment: Three untouched boxes possible(Deduct the 6 fixed boxes)

Skin: Blue by Barbara Chamberlin
My best solution pushes 543/190, moves 575/176. Same for the sharpened version.
JSoko has been working for a few hours now but I don’t think there’ll be more untouched boxes.
I found 9 untouched boxes for Mazda Left and 12 untouched boxes for Mazda Right with JSoko.
阿谦 beat that with 15 untouched boxes for Mazda Left and 13 untouched boxes for Mazda Right.
So I need to make a new Mazda level. I promise it will not be flawless but I will also promise it will have fewer untouched boxes than the first version.
You will find the new Mazda level on this page but not in a short while.

Comment: With a wall at B9 I found a solution with 9 untouched boxes.
Date: 2025-07-27
Skin: Lilliput by Gerry Wiseman
In the levelfile you will find Mazda Left with a wall at B9 and Mazda Right with a wall at P9.
I used the optimizer in JSoko to search for untouched boxes. 9 in Mazda Left and 12 in Mazda Right.
I guess I would never have found that manu untouched boxes without JSoko. Thanks for that function.
Can you find more untouched boxes than JSoko ?

Skin: Boxworld 29*10 2016
More than five years ago Anian sent me a screenshot showing two boxes need not be touched. One more than I knew.
It has been nagging me since then.
But not anymore. In the file you will find
- Rod of Asclepius Original (Circular Challenge 48)
- Rod of Asclepius Sharpen. Sharpen means you have made no changes except stoned floors and stoned boxes. Actually I could have included stoning C3 and D3 in the sharpened level
- Rod of Asclepius Remodel. Remodelling a level mens bigger structural changes. Here the layout of the rod is totally unaltered but the bottom of the level is changed considerably. You need to move all the boxes to solve the level
Enjoy

Looking for a theme for my next Sokoban project I considered the chinese zodiac.
But decided against this. No clearcut pictograms. Lots of sokoban authors are better with chinese signs than me. Make levels look like animals are difficult…
And it has been done before:

Didn’t like my first version of Cancer either. So here is the new one. 4 boxes need not to be touched. Probably no more but tell me if you find one. You can look for untouched floors too.
Oops. This is an image of the solved level 🙁
Well, then you know the end position 🙂

Time for a collection ?
Maybe but you might be in for a few surprises.
My best solution for Virgo? 1283/317
In the last versions of JSoko Matthias Meger added a useful feature in the optimizer. JSoko can search for solutions with maximum untouched boxes. And you can mark a box/floor as untouched so the optimizer will search for solutions without using the marked square.
Matthias send me an example (below left) how the optimizer found 2 more untouched boxes than my handmade attempt.
The result depends on the given solution. With my solution the optimizer also found 4 untouched boxes (below right) with a slightly different configuration.
In Matthias’ sharpened version G18 can be an untouched floor. Not in mine.

I never really liked my first Gemini.
Even less when Kevin29 and Premyzl Zika found 8-10 or more dead boxes.
This version is much less dead. I found two variants. One with one dead box and one wit two different dead boxes.
Can you find them ?
Tell me if you find more.

油纸成伞 and Anian showed me you don’t need to move the upper part of the X to solve the puzzle. Not so with the revised version. Now only one box can be left untouched.

At the start Sagittarius was so complex/big that Festival didn’t solve it.
When I reduced the level to the bare necessities Festival eventually managed to find a solution.
Humans might not have an easier time.. Less room for not optimal solutions.
One box need not to be moved. Tell me if you find more.

Not big differences. Just walls at F5 and L7-L8.
Anian didn’t suggest changes but his solutions showed me several times how the level could be improved. At least if you like it tougher 🙂 Fair to be credited as coauthor.
My best moves/pushes 620/170, pushes/moves 728/160.
4 boxes and 2 floors can be changed to walls.
The solutions for a changed level works with the the original of course but is slightly longer. Moves/pushes 664/168 and pushes/moves 746/160.
Don’t check my latin. I only used doctors latin for the last fifty years.

Spent a lot of time creating Pisces1 and was really happy with the result. Necessary to go both ways from the top. Necessary to move everything in the bottom. Necessary to move a lot in the top.
Anian sent me a screenshot to show that the last really is not the case:
10 boxwalls and 2 floorwalls nicely symmetrically arranged. And Anian claims there is one more boxwall.
A crappy level not worth my harddisk.
I needed to redesign. More to do in Pisces2. So far I found only 2 boxwalls and 1 floorwall.
Anian showed me that when you choose the right tweaks(=vicinity search) JSoko often performs better than YASO.
My best results optimized by JSoko: Pushes 524/178. Moves 610/160
And happy again to tell no solver will help you.

Again. No. A solver will not help you.
My best solutions: Moves 454/152. Pushes 510/138
Both solutions contains 6 boxwalls and 1 floorwall. But not the same.
I didn’t look further for boxwalls or floorwalls. There might be some. Please mail me if you find some.

By just solving the level and optimizing it with Yasc (The best optimizer by far. If you know any better, please let me know) I found 10 boxwalls and 2 floorwalls. I didn’t look much further.
Any more?
Please mail me if you find something interesting.
My best solution by the way 553/141
2025-01-12 How about the threequel ?
Once in a while I get comments and suggestions for my levels.
I really appreciate the interest. It often helps me build a better level.
Jordi Domenech send me a solution for Newyear 2025 much shorter than my best.
A total rebuild was necessary.
Anian send me a screenshot showing me what are not needed to move in the rebuild level.
A less drastic rebuild was necessary.

My best solution 432/140.
The level is solvable without moving the 8 marked boxes. Then my solution grows to 576/153.
A version of the lewel with 8 fixed boxes is included in the levelfile.
Enjoy
2025-01-07. The Sequel is never better?
Jordi Domenech send me a solution for Newyear 2025 more than 200 moves better than my best solution. With lots of boxes not needed to touch.
I had to try something else:

Comment: The Sequel is never better?
Date: 2025-01-07
Not necessary easier but more funny to solve I guess. Still at least 8 boxes not needed to move.
My best with 7 boxes unmoved 459/138. Probably improvable.
