Click a square in the same row or column as the black tile, to move the black tile to that square.
Alternatively, click one of the row or column labels to move the black tile to that row or column.
Click "Reset" to emulate the reset lever, and "Big Red Button" to emulate pressing the red button.
You may also enter a sequence of moves into the text box - R represents reset and P represents pressing the red button.
Click "Do sequence" to execute all the moves, or "Do step" to execute the next move.
The following sequence solves the puzzle:
E 3 F 5 B 4 C 2 F 6 D 5 C 3 B 6 C 3 F 6
R
C 5 A 6 F 5 A 6 C 5 B 4 C 6 F 2 C 6 F 2 C 6 F 4 E 5 C 6 F 4 E 5
2 A 3 C 2 B 3 F 2 C 3 E 2 D 3 F 2 B
5 E 4 F 6 B 2 F 6 B 2 F 6 B 2 F 3 C 2 F 6 B 4 C 2 F 4 E 2 B 4 C 3 4 B C 3
P
After the above sequence, repeat the sequence 4 3 4 B C 3 P to produce more bars.
