Sokoban Level 1k
Sokoban Level 1k is one of the new maps for Sokoban in some variants of NetHack. It may appear as a first level map for Sokoban in UnNetHack, and may additionally appear as a second level map in EvilHack. It has 10 boulders and pits, leaving no spare boulders.
In UnNetHack, this level may be flipped horizontally or vertically like all Sokoban levels.

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 pit (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 pit.
First, rearrange the boulders in the upper chamber to fit another boulder from the middle chamber:
----------------- A l
|..^^....#......| D r
|..--....#..A.B.| F uuuu
--^|<....#.C.D..|
|^---------.--.|
|..^^^^^^...||.|
|??------.EF--.--
---- |.G....@|
---.----.--
|.H.I....|
|..J.-----

Push the first boulder in:
----------------- G r
|..^^....#......| E ull*
|..--....#.AF.B.|
--^|<....#.C@.D.|
|^---------.--.|
|..^^^^^^...||.|
|??------.E.--.--
---- |.G....>|

|.H.I....|

Push a couple of boulders from the bottom chamber into the pits:
----------------- I l
|..^^....#......| J r
|..--....#.AF.B.| I uuuu ll*
--^|<....#.C..D.| H ruuu ulll*
|^---------.--.|
|..^^^^^.@..||.|
|??------...--.--

Use three more boulders to finish the first corridor of pits:
----------------- G lluu llll*
|..^^....#......| J uluu uull lll*
|..--....#.AF.B.| F dddd dllu ulll lll*
--^|<....#.C..D.|
|^---------.--.|
|..^^^.@....||.|

Pick up the scrolls of earth and finish with the last four boulders:
----------------- D lldd ddll uull llll llu*
|..^^....#......| B lldd dddl luul llll lllu u*
|..--....#.A..B.| C rddd dllu ulll llll luuu ur*

Next level
UnNetHack
UnNetHack's Sokoban branch has only three levels per game, collapsing the 'second' levels into the first floor, so the first level leads straight to the pool of third levels:
