TTraffic is a Tcl/Tk version of the board game Rush Hour created by Binary Arts Coporation. The goal is to remove the red car(s) out of the grid through the slot on the right. To do this you have to slide the other cars out of the way. TTraffic is inspired by GTraffic, the Gnome version Rush Hour. TTraffic comes with about 15.000 puzzles ranging from intermediate to expert. These puzzles were automatically created by the program gtlevel.
