Sokoban Level 1g
This is one of the new possible maps for Sokoban Level 1 in UnNetHack. It has 24 boulders and 36 pits, but only the 16 bottom-most pits need to be filled, leaving 8 spare boulders. Like all Sokoban levels in UnNetHack, this level may be flipped horizontally or vertically.

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 relevant boulders are replaced by letters so they can be referred to. Since untouched boulders are still shown as '0' (zero), letters 'O' and 'Q' are skipped for clarity.
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, open a path into the half of the boulder ring closest to the stairs:
----------------------------- J uu |.............|.............| E l |.0..|.A.|....#.............| |.0.|.B|C.|...#.............| |.0|.D...E....#.............| |...F...|.G|..#.............| |0|.H..|..I.|J#.............| |..|K.|...L...#.............| |....M...N.|0.#.............| |...|.P|R.|.0.#.............| |....|.S.|..0.#.............| |............@|<............| |-.-#########---#########-+-| |..^^^^^^^^^^?.?^^^^^^^^^^..| |..^^^^^^^^.......^^^^^^^^..| -----------------------------
Solve the four boulders nearest the pits:
----------------------------- M llld dddd dr* |.............|.............| R ddll llll dddr r* |.0..|.A.|....#.............| P ddll lldd drrr* |.0.|.B|C.|...#.............| S ldll lldd drrr r* |.0|.D..E@...J#.............| |...F...|.G|..#.............| |0|.H..|..I.|.#.............| |..|K.|...L...#.............| |....M...N.|0.#.............| |...|.P|R.|.0.#.............| |....|.S.|..0.#.............| |............>|<............| |-.-#########---#########-+-| |..^^^^^^^^^^?.?^^^^^^^^^^..| |..^^^^^^^^.......^^^^^^^^..| -----------------------------
Solve the rest of this half of the boulder ring:
----------------------------- L l |.............|.............| N llll llld dddd drrr rr* |.0..|.A.|....#.............| L dlll llll dddd ddrr rrrr* |.0.|.B|C.|...#.............| I lddl llll lldd dddd rrrr rrr* |.0|.D..E....J#.............| G ddld llll llld dddd drrr rrrr r* |...F...|.G|..#.............| |0|.H..|..I.|.#.............| |..|K.|...L...#.............| |........N.|0.#.............| |...|..|..|.0.#.............| |....|...|..0.#.............| |............>|<............| |-.-#########---#########-+-| |..^^^^^^^^^^?.?^^^^^^^^^^..| |....@.^^^^.......^^^^^^^^..| -----------------------------
Pick up the two scrolls of earth and begin work on the other half of the boulder ring, starting with the boulders nearest to the pits:
----------------------------- F ll |.............|.............| H r |.0..|.A.|....#.............| K dlld dddd drrr rrrr rrrr rrrr r* |.0.|.B|C.|...#.............| H lddl lddd dddr rrrr rrrr rrrr rrrr* |.0|.D..E....J#.............| B d |...F...|..|..#.............| D ddld dlld dddd drrr rrrr rrrr rrrr rrr* |0|.H..|....|.#.............| B lddl ddll dddd ddrr rrrr rrrr rrrr rrrr r* |..|K.|.......#.............| |..........|0.#.............| |...|..|..|.0.#.............| |....|...|..0.#.............| |............>|<............| |-.-#########---#########-+-| |..^^^^^^^^^^?.?^^^^^^^^^^..| |........@........^^^^^^^^..| -----------------------------
Use the clump of three boulders furthest from the pits to fill them:
----------------------------- A lddd lldd dlld dddd drrr rrrr rrrr rrrr rrrr r* |.............|.............| E llld dldd lldd dddd rrrr rrrr rrrr rrrr rrrr r* |.0..|.A.|....#.............| C dlll ddld dlld dddd drrr rrrr rrrr rrrr rrrr rrr* |.0.|..|C.|...#.............| |.0|....E....J#.............| |.F.....|..|..#.............| |0|....|....|.#.............| |..|..|.......#.............| |..........|0.#.............| |...|..|..|.0.#.............| |....|...|..0.#.............| |............>|<............| |-.-#########---#########-+-| |..^^^^^^^^^^...^^^^^^^^^^..| |...................@.^^^^..| -----------------------------
Fill in the final pit with the last useful boulder:
----------------------------- F rrdd dlld dddd drrr rrrr rrrr rrrr rrrr rrrr* |.............|.............| |.0..|...|....#.............| |.0.|..|..|...#.............| |.0|.........J#.............| |.F.....|..|..#.............| |0|....|....|.#.............| |..|..|.......#.............| |..........|0.#.............| |...|..|..|.0.#.............| |....|...|..0.#.............| |............>|<............| |-.-#########---#########-+-| |..^^^^^^^^^^...^^^^^^^^^^..| |......................@.^..| -----------------------------
The level is now complete. Any of the eight remaining boulders may have items underneath them:
----------------------------- |.............|.............| |.0..|...|....#.............| |.0.|..|..|...#.............| |.0|.........J#.............| |.......|..|..#.............| |0|....|....|.#.............| |..|..|.......#.............| |..........|0.#.............| |...|..|..|.0.#.............| |....|...|..0.#.............| |............>|<............| |-.-#########---#########-+-| |..^^^^^^^^^^...^^^^^^^^^^..| |.......................@...| -----------------------------
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:
