It's gridlock and the little red car can't move. The player is a traffic cop in the Rush Hour Traffic Jam Puzzle where the objective is to get the red car off the road. To play, pick one of 40 challenge cards; solutions are printed on the back of each card. Then set up the cars and buses in a specified pattern on the 6-inch-square road grid. Move the vehicles one by one (obey those traffic laws!) until the red car can escape the traffic jam. There are four levels of difficulty. Kids can alternate turns with another player or just "play in traffic" alone. The game from Binary Arts received a national award from Mensa and is used in elementary school math classes. The design includes clear instructions printed on the sturdy box, which can be used both as a playing tray and for storage. The game cards stow away in a drawer in the road grid. This is a 1999 Parents' Choice recommended toy. --Marcie Bovetz Review Forty cards each show a different version of total gridlock, with one red car hemmed in by other vehicles that block the single exit. Select a card and replicate its pattern on the playing surface, then figure out the right sequence of moves to shift obstructing cars and trucks out of the way. Solutions are included. (Ruth B. Roufberg, Parent's Choice®, 1996) -- From Parents' Choice® See more
