This first Sokoban level is not very hard. The level has 12 boulders and 10 pits, so 2 boulders are spare. In the level (as well as in level 1b) are two scrolls of earth.
-------- ------ 0 boulder |<|>...---....| ^ pit |^|-.00....0..| > starting position/downstairs |^||..00|.0.0.| < upstairs |^||....|.....| ? scroll of earth |^|------0----| |^| |......| |^------......| |..^^^^0000...| |??-----......| ---- --------
Strategy
The following solution solves the level without putting any blocks in an immobile position. Faster solutions which do not necessarily leave every boulder free might exist.
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.
This is the starting position. First, clear the way into the lower right room:
-------- ------ A d |<|@...---....| B rrrr |^|-.AB....C..| H dd |^||..DE|.F.G.| |^||....|.....| |^|------H----| |^| |......| |^------......| |..^^^^IJKL...| |??-----......| ---- --------

Pickup the two scrolls of earth, then clean the upper right room. There are several ways to do this, here is one.

Take one of the remaining boulders and finish the level:
