Boxxle 1 Hidden

While checking out the Sokoban Online version of Boxxle 1, I found that there is a hidden puzzle in that game. I have been trying to solve it, but am running into a problem:

The puzzle according to Sokoban Online:


  Level: 'Perfect / Level 303 R--13' Nr: 391 Collection: 'Thinking Rabbit Arranged'

After previewing this post I see that this level occurs in "Perfect / Level 303 R--13' Nr: 391 Collection: 'Thinking Rabbit Arranged" (and I guess in the original Perfect as well).

I have been able to open it up to this point:


  

Beyond this point I have been unable to solve. I keep getting stuck. Can anyone offer me a clue as to what to do now?

Edit: I decided to make my snapshot available for those who may want to see how I reached the point I show above:

  Moves/Pushes/Box-lines/Changes/Steps/Pusher-lines: 571/89/61/57/56/315

Hidden puzzle?

The level is not new as it was posted on this site long time ago.

Just curious, how do you access this hidden puzzle?

I just did a search, the level you mentioned is just an easier version of the similar level in the Perfect set -- level 303 of the Perfect set.

York Shen created two slightly harder levels:

It plays mostly the same except that it requires slightly more effort on the left hand side.

There are many more remodels of this level where the right hand side is also changed.

I found it on Sokoban Online. From their site:

Description
This is the hidden puzzle you can play when entering the pass code "Q, Spade, X, 4" into the Gameboy game Boxxle.

As I commented in the original post, I noticed that it was the same puzzle as Level 303 of Perfect. In comparing it with that level I have not found any difference. I will look again.

Edit: OK I found the difference:

Perfect 303:


  

Boxxle 1 Hidden:


  

I guess that could make one of them more difficult to solve than the other, but have yet to solve the hidden one, so I can't say how this difference affects the solution.

Thanks, ben. I will check these out as well.

well, it's obvious that the one you mentioned for Boxxle has one extra space when compare to the Perfect level. Thus, it makes the Perfect level harder.
Once you figured out the proper way to solve it, this space doesn't really matter. As such, you can directly play York Shen's change.
Once you solved that, the other two (boxxle and perfect) levels are solved as well.
Not difficult if you ask me. The trick for solving most sokoban levels is to figure out how the level ends and how the boxes are placed before it ends. Once you figured that out, most of the time, the level becomes easy to deal with, just a matter of unlocking boxes. Usually, I don't like to give solutions because that really spoils the fun of playing Sokoban.

I can understand that you don't like to share solutions. That is why I only asked for a hint of where to move next, as I did open the level enough to go around and around, but when I try to put the boxes away I get stuck. That is also why I included the snapshot of the moves I had made thus far, as that could be used to see how I got to where I am.

As for the fun of sokoban, I love this game, and I will likely be playing it for the rest of my life, but it becomes very frustrating to me when I try repeatedly to get past a hurdle with no success. Maybe I'm just getting old, but my ability to keep beating my head against the same wall for months and years is dwindling. I find myself asking for help because I just don't understand what I am doing wrong. If there is a way to help me learn where I am screwing up without giving the solution away then I am all for it. If the only way is to divulge the solution, then I don't know what to tell you.

There are also some puzzles/sets that I will never solve. I won't even try because I do not understand them at all. They are the Orimaze puzzles. One was solvable using YASS. I have studied that solution ad nauseum and am still lost to it. I decided that those puzzles are not worth the effort for me, so I will happily let others wrap their heads around them.

@WayneCa, I will give you a big hint and tell you the general flow on solving it. If you're still stuck after that, I can give you the solution.

Looking at your partial solution in the #1 post, you're not sure how to close the level. It also shows that you're a pretty good player.
Good players usually don't easily close a path.
However, at some point, you need to make a decision to close it.
Usually, when you run out of room -- like in this case.
It should be clear to you that if the above section has one extra room, then you can push the R7 box into the upper middle section and then you can close the level in the upper middle section.

You just need to find that space to place one extra box.
Look at the level, there's no extra space left.
When you run out of spaces, you need to look at level and see what places can be filled or what paths can be closed to create more space.

Take a close look at the level, the left hand side of the level can be filled first provided there is enough room on right hand side to move.

Continuing from your moves in #1,
do these:
dddllldllldlldllllluururUddllddrrrrrurrd
LruurrdLrruurrdLLurrruuuruulDDDuullllull
lluuululldddDuuuurrdrruLL

Basically, it fills all those goals on the left, it leaves room on the bottom-right section to move.
And to create the extra space you want to store an extra box in the upper-middle section, you need to close the path on the top leading to the left.

The level should look like this now.


  

From this position, you will be able to push a box into the upper-middle section from the bottom-right. Then close the bottom-right, then finish the level in the upper-middle.

The other two levels from York Shen can be solved in a similar manner, just that the left hand side is played slightly different.
However, the general concept is the same -- get the left hand side done, then close path on the top to the left to create room. The ending plays the same like before.

@ben you rock! After seeing where your moves left me, I could see how I wasn't seeing the lower-right the way I should have. That helped me alot. Then all I had to do was figure out how to move everything around in the upper-middle so I could get that box in there. It only took about 10 tries before it fell into place. It is now solved and I feel much better about tackling the remodeled versions.

Thanks for the help! Smile

Good to know that you solved it.

The left hand side is not tight at all.
Based on Y2, the left hand side can be tighter.
