Sokoban Level 3f
Sokoban Level 3f is one of the new maps for Sokoban in some variants of NetHack. It may appear as a second level map in UnNetHack, and may also appear as a third level map in SlashTHEM and Hack'EM. In Hack'EM, the level map is named "Reading Rooms". It has 13 boulders and holes, leaving no spare boulders.
In UnNetHack, this level may be flipped horizontally or vertically like all Sokoban levels.
--------- 0 boulder
|...|...---- ^ hole
|.0.+......| > starting position/downstairs
|...|0|..|.| < upstairs

Strategy
The following solution may not be very fast or organized. Improvements welcome. Like all Sokoban levels it can be solved without making any boulders 'stick'.
All boulders are replaced by letters so they can be referred to. Moving the boulders is shortened to r for right, l for left, u for up, d for down. An asterisk is used to denote the last move filled a hole (and thus removed the boulder from the game). So "N ddrr*" means move boulder N two times down and two times to the right into a hole.
First, get to the holes:
--------- G uu
|...|...---- D rrrr r
|.A.+......|
|...|B|..|.|
-----------....|C|
|......D.........|
|.|.|.E--.|.|..|^|
|...|F....|....|^|
--G|.H.-------+-|^|
--...I..|....|...|^|
|...J|..#....#.K.|^|
|..L...-|....|...|^--
|.M-----|....|----..|
|@.|<^^^+....+^^^^..|
---------------------
Fill the first six holes with the nearest boulders, counting the ones behind the locked doors:
--------- C dd*
|...|...---- D rrrr dd*
|.A.+......| K uuuu urrr ddd*
|...|B|..|.| A rrrr rddd rrrd ddd*
-----------....|C| B ulll rrrr rddd rrrd dddd*

|G|.|.E--.|.|..|^|
|...|F....|....|^|
--.|.H.-------+-|^|
--...I..|....|...|^|
|...J|..#....#.K.|^|
|..L...-|....|...|^--
|.M-----|....|----..|
|>.|<^^^+....+^^^^..|
---------------------
Open up a loop near the middle:
--------- F dd
|...|...---- H l
|..........| I l
|...|.|..|.| F uuu
-----------....|.| I rrr
|................|
|G|.|..--.|.|..|.|
|...|F....|....|.|

--...I..|....|...|.|
|...J|..#....#...|@|
|..L...-|....|...|.--
|.M-----|....|----..|
|>.|<^^^+....+^^^^..|
---------------------
It is now possible to fill the next four holes with boulders:
--------- F u___ ____ _ rrrr rrrr rrrd dddd dddl*
|...|...---- I uuuu ____ _ rrrr rrrr rrrd dddd dddl l*
|..........| H drru uuu_ _ rrrr rrrr rrrd dddd dddl ll*
|...|.|..|.| J urrr uuuu _ rrrr rrrr rrrd dddd dddl lll*
-----------....|.|
|................|
|G|.|F.--.|.|..|.|

--.....I|....|...|.|
|...J|..#....#...|@|
|..L...-|....|...|.--
|.M-----|....|----..|
|>.|<^^^+....+^^^^..|
---------------------
Make sure to open the doors before continuing. After doing so, the final three boulders can be pushed into place:
--------- G dddr rrr_ _ uuuu rrrr rrrr rrrd dddd dddl llll llll ll*
|...|...---- M uurr urrr _ uuuu rrrr rrrr rrrd dddd dddl llll llll lll*
|..........| L lurr urrr _ uuuu rrrr rrrr rrrd dddd dddl llll llll llll*

The level is now complete:
