I spent hours playing this game and now i want to share my addiction with you 
From market:
The game is styled in a dieselpunk theme inspired by Bioshock.
The gameplay is reminiscent of Tetris ( and plumber : )) but is even more addictive as it requires more thinking.
Build the high voltage circuit and watch it disappear in colourful sparks of tameless electricity. Race against the ticking timer or relax in unlimited mode. Compete with other players through OpenFeint scoring system.
REQUIRES ANDROID:
2.2 and up
