Seemingly impossible scores?

I've seen many games that have been solved with scores that seem impossible. One example is Bugs Collection 138, level 138. The best score is 237 moves/111 pushes, and I can't see how it could possibly be solved with so few moves & pushes. Here is the level:


  Level: '138' Nr: 136 Collection: 'Bugs Collection 138'

There is a lot to do in that level, and by the time I get to 237 moves there is quite a bit of it still unsolved.

Another example is Boxxle 1, level #1. The best score is 89 moves/31 pushes. But no matter how I play it I can't get it better than 93/31. Here is the level and my moves:


  Level: '#1' Nr: 1 Collection: 'Boxxle 1'

  Moves/Pushes/Box-lines/Changes/Steps/Pusher-lines: 93/31/16/3/16/58

There are many games like this in all collections. How can can this be possible?

It is possible to have 89/31:

And for the other level, here's the 2378/111 moves solution:

Thank you, ben. I seem to be lacking in a particular sense of strategy with Sokoban, even before my 5-year break (been playing since 2001). I could always solve most levels, but never able to get the numbers down, even on the simplest ones, LOL.

Since coming back to it I'm trying to focus more on lowering my old scores, and it's frustrating most times. I appreciate your help. Smile

Different people seem to enjoy Sokoban differently.
Personally, I don't enjoy doing optimization even when I know most of methods for doing so. It is a time consuming task that I don't enjoy doing. (not to mention that YASO can optimize most of the solutions without any human interaction. And yes, there are times it requires some new thinking from the player before better results can be achieved)

I also enjoy exploring different ways to solve the same level, but the goal is not for shorter solution, but looking for ways to forcing more moves, for making the level harder to solve.
