Alan Bellows of Damn Interesting is offering up a browser game that may drive you crazy. The object is to diffuse a bomb by flipping levers in a certain order, but there are 28 levers and if you make one wrong move, the whole building explodes. I don't know what happens if you win, because I've blown up the building every time so far.
The occasion for the game launch is to commemorate an article published exactly five years ago about an incident that occurred exactly 40 years ago. In August of 1980, a mysterious machine appeared in the back area of Harvey's Wagon Wheel Casino in Lake Tahoe, Nevada. It was a metal box with 28 toggle switches on its face. A nearby note explained that it was a bomb. The writer demanded three million dollars to be delivered in an extremely convoluted way, or the bomb would be detonated. Examination proved the device to be quite complex, and unable to be moved safely. Before long, authorities involved included the bomb squad from the local sheriff's office, plus "FBI Special Agents, the local Fire Chief, the state Fire Marshal, a military bomb disposal squad, representatives from the Nuclear Emergency Support Team, and scientists from both the Naval Surface Warfare Center and Lawrence Livermore National Laboratory." As far as the delivery of the ransom, well, the very complexity of the instructions caused that operation to go awry. The Zero-Armed Bandit is a fascinating true story that would make a good movie.
