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.
You can watch an instructional video.
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 Nddrr* means move boulder N two times down and two times to the right into a pit.
Clear the lower left, make sure you move J to the right and do L before J, then clear A and B:
-------------------- M lrrr rrr* |........|...|.....| J r |.AB..-CD|.-.|.....| L drrr rrrr* |..|.E.F.|GH.|.....| J ddrr rrrr r* |-.|..-..|.-.|..<..| A dddd dddr rrrr rrrr* |...--.......|.....| B lddd dddd rrrr rrrr rr* |...|.I.-...-|.....| |.J.|K.|...--|.....| |-L.|..-----------+| |..M....^^^^^^^^^^.| |...|.@------------- --------
Clearing the top room is probably the hardest part of the level. Push E up and enter the top room by moving D down, so you can remove F and then E:
-------------------- E u |........|...|.....| D dd |.....-CD|.-.|.....| F lllu |..|.E.F.|GH.|.....| E d |-.|..-..|.-.|..<..| F lldd dddd drrr rrrr rrrr* |...--.......|.....| E lull dddd dddr rrrr rrrr rrr* |...|.I.-...-|.....| C dlll ulld dddd ddrr rrrr rrrr rrr* |...|K.|...--|.....| |-..|..-----------+| |..........@.^^^^^.| |...|.>------------- --------
Fill the last two holes with I and K:
-------------------- I dddr rrrr rrrr r* |........|...|.....| K ddll lrrr rrrr rrrr rrrr* |.....-..|.-.|.....| |..|.....|GH.|.....| |-.|..-.D|.-.|..<..| |...--.......|.....| |...|.I.-...-|.....| |...|K.|...--|.....| |-..|..-----------+| |.............@.^^.| |...|.>------------- --------
The level is now finished. Remember to check under and behind the unmoved boulders for usable items.
