Sokoban Level 1h
Sokoban Level 1h is one of the new possible maps for Sokoban in variants of NetHack. It may appear as a first-level map in UnNetHack and SpliceHack-Rewrite, and may appear as a second level map in SLASH'EM. It has 8 boulders and 7 pits, leaving 1 spare boulder.
Like all Sokoban levels in UnNetHack, this level may be flipped horizontally and/or vertically. In SLASH'EM, the pits are replaced with holes; the scrolls of earth are still present as well.
-------- 0 boulder |......| ^ pit/hole |..0...----- > starting position/downstairs |---...0...| < upstairs |..--0|.0..| ? scroll of earth |....>|.|.----- |^--.0.0.00..?| --^||..|...|..?| |..------------- |...^^^^^<| -----------
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, push the two boulders next to the entrance into the upper chamber to make some room:
-------- C uu |......| A l |..A...----- C l |---...B...| E uuuu |..--C|.D..| |....@|.|.----- |^--.E.F.GH..?| --^||..|...|..?| |..------------- |...^^^^^<| -----------
Get into the lower middle chamber and push another boulder out of the way:
-------- F r |......| G uuu |.A.CE.----- |---.@.B...| |..--.|.D..| |....>|.|.----- |^--...F.GH..?| --^||..|...|..?| |..------------- |...^^^^^<| -----------
Push the first couple of boulders into pits, taking the scrolls of earth in the back chamber on the way:
-------- F llll ulll d* |......| H rrll llll llul lldd* |.A.CE.----- |---...B.G.| |..--.|.D@.| |....>|.|.----- |^--....F.H..?| --^||..|...|..?| |..------------- |...^^^^^<| -----------
The next boulder needs to be solved specifically to prevent the other boulders from getting stuck:
-------- E dddd rrrl lllu llld dddr r* |......| |.A.CE.----- |---...B.G.| |..--.|.D..| |....>|.|.----- |@--..........| --.||..|...|...| |..------------- |...^^^^^<| -----------
Push boulders to fill the last four pits:
-------- D l |......| B lldd dlul lldd ddrr r* |.A.C..----- D ddll lull lddd drrr r* |---...B.G.| G llll dddl ulll dddd rrrr r* |..--.|.D..| C rddd dlul lldd ddrr rrrr* |....>|.|.----- |.--..........| --.||..|...|...| |..------------- |..@.^^^^<| -----------
The level is now complete. Check the space under the final boulder if you haven't already:
-------- |......| |.A....----- |---.......| |..--.|....| |....>|.|.----- |.--..........| --.||..|...|...| |..------------- |......@.<| -----------
Next level
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:
