This was a Flash-based game that I made in 2004 to be played on Flash-enabled desktop machines, which were ubiquitous at the time.  It was later ported over onto the Android platform to be playable on all mobile devices (except iPhones, of course) in 2007.

SCI was modeled after a  1981 Japanese puzzle game called Sokoban, and borrowed heavily from its mechanics.    The game was played on a board of squares, where each square is a floor or a wall. Some floor squares contain ciggy machines, and some floor squares are marked as electrical outlets.

The player is confined to the board, and may move horizontally or vertically onto empty squares (never through walls or ciggy machines). The player can also move into a ciggy machine, which pushes it into the square beyond. Ciggy machines may not be pushed into other machines or outlets, and they cannot be pulled. The number of ciggy machines is equal to the number of outlet locations. The puzzle is solved when all ciggy machines are at electrical outlet locations.
