Welcome to the crazy world of the newspaper boy!
Screw the nut is a classic puzzle/mind game. Your aim is to put the nut on the screw (pretty much as the name of the game implies). Those days there are many similar games to that one, but when he released, on May/2010 it was unique and new.
Playing the game today, almost 4 years since it was released is still fun. The levels are still challenging, the graphics and nice and you can feel the Kongregate sponsored a high quality game here.
There are 22 levels in the game, and it becomes challenging since level #5 which requires fast action. Of course there is a solution to all of the levels, you have to press the "see solution" button at the top of the game in order to watch it.
I enjoyed playing that game.
