This is a simple, fun, and nerve-wracking game based on the old "hot potato" idea. You twist the top "fuse" of the bomb and it starts ticking. Then you toss it around to your friends. If the bomb's timer runs out and makes an "explosion" sound, the person holding the bomb is out of that round. If the bomb is in mid-air, the person to whom the bomb is being tossed is out of that round. The last person left is the winner.
Time Bomb was made out of a hard plastic material. If you played toss with it on a hard floor and it was dropped, it cracked and broke quite easily. This was a popular game and was manufactured by Milton Bradley for several years.
