# Sokoban Level 1l

Sokoban Level 1l 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 appear as a second level map in SLASH'EM and EvilHack. It has 14 boulders and pits, but only 13 of the pits need to be filled, leaving 1 spare boulder.

In UnNetHack, this level may be flipped horizontally or vertically like all other Sokoban levels; in EvilHack, the extra pit is replaced with lava.

## 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.

Before starting, check the room with the locked door and pick up any wands there; a monster with a wand can zap it at you through the iron bars while you solve the puzzle. Once that's done, fill in the first boulder:

```          ----       H uull*
---|..----
|..|...A.|---
----  |....B|C.|..|
|??----.|...|...D.|
|...^^^.....|--E..|
|^--#--...|F|..G.--
|^|...|-H-|.IJ...|
|^#.^.....|....K.|
--^|...|.L..@M..---
|..--#-----N|.---
|..^^^^^^<|...|
---------------
```

Arrange the boulders in the lower right chamber for easy movement later:

```          ----       J d
---|..----    G l
|..|...A.|--- D d
----  |....B|C.|..| E d
|??----.|...|...D.|
|...^^.@....|--E..|
|^--#--...|F|..G.--
|^|...|-.-|.IJ...|
|^#.^.....|....K.|
--^|...|.L..>M..---
|..--#-----N|.---
|..^^^^^^<|...|
---------------
```

Solve the next two boulders in the upper right chamber:

```          ----       A llld ddll lll*
---|..----    C ulll dddl llll l*
|..|...A.|---
----  |....B|C.|..|
|??----.|...|.....|
|...^^......|--@D.|
|^--#--...|F|.GE.--
|^|...|-.-|.I....|
|^#.^.....|..J.K.|
--^|...|.L..>M..---
|..--#-----N|.---
|..^^^^^^<|...|
---------------
```

Pick up the scrolls of earth if applicable, then prepare the top-most boulder to be pushed while opening up a passage in the lower right chamber:

```          ----       B u
---|..----    J r
|..|.....|--- D u
----  |....B|..|..|
|??----.|...|.....|
|....@......|--.D.|
|^--#--...|F|.GE.--
|^|...|-.-|.I....|
|^#.^.....|..J.K.|
--^|...|.L..>M..---
|..--#-----N|.---
|..^^^^^^<|...|
---------------
```

Solving the next boulder sets the pattern for the seven boulders after it:

```          ----       B ____ ____ ____ __ lddd llll llll ld*
---|..----    F uuuu ____ ____ __ lddd llll llll ldd*
|..|.B...|--- I luuu uu__ ____ __ lddd llll llll lddd*
----  |.....|..|..| E dlll luuu uu__ __ lddd llll llll lddd d*
|..----.|...|...D.| G rdll lluu uuu_ __ lddd llll llll lddd dddr*
|...........|--.@.| D dldd llll uuuu u_ lddd llll llll lddd dddr r*
|^--#--...|F|.GE.-- J ulll uuuu u___ __ lddd llll llll lddd dddr rr*
|^|...|-.-|.I....|  K llul luuu uu__ __ lddd llll llll lddd dddr rrr*
|^#.^.....|...JK.|
--^|...|.L..>M..---
|..--#-----N|.---
|..^^^^^^<|...|
---------------
```

The boulders near the downstairs fill the last two pits:

```          ----       M r
---|..----    N urr_ uulu uuuu lddd llll llll lddd dddr rrrr*
|..|.....|--- M l___ uulu uuuu lddd llll llll lddd dddr rrrr r*
----  |.....|..|..|
|..----.|...|.....|
|...........|--...|
|.--#--...|.|....--
|.|...|-.-|......|
|.#.^.....|......|
--.|...|.L..>M..---
|..--#-----N|.---
|....@.^^<|...|
---------------
```

The level is now complete. Check under the final boulder in case an item happens to be underneath:

```          ----
---|..----
|..|.....|---
----  |.....|..|..|
|..----.|...|.....|
|...........|--...|
|.--#--...|.|....--
|.|...|-.-|......|
|.#.^.....|......|
--.|...|.L..>...---
|..--#-----.|.---
|......@.<|...|

```

## 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:
