Ok so not exactly games but will annoy you just as much!
Apparently there are two solurtions to this one, i've yet to find them!
U2 has a concert that starts in 17 minutes and they must all cross a bridge to get there. All four men begin on the same side of the bridge. You must help them across to the other side. It is night. There is one flashlight. A maximum of two people can cross at one time. Any party who crosses, either 1 or 2 people, must have the flashlight with them.
The flashlight must be walked back and forth, it cannot be thrown, etc. Each band member walks at a different speed. A pair must walk together at the rate of the slower man's pace:
Bono: 1 minute to cross Edge: 2 minutes to cross Adam: 5 minutes to cross Larry: 10 minutes to cross
For example: if Bono and Larry walk across first, 10 minutes have elapsed when they get to the other side of the bridge. If Larry then returns with the flashlight, a total of 20 minutes have passed and you have failed the mission.

The way that that is phrased, the puzzle is impossible. If bono, the fastest (1 min) went each time, it still doznt work

yeah.... sure.... whatever you say...
Maybe you were after getting up after a long restful sleep and that _was_ you thinking straight.
What to believe?! Oh what to believe!??!
its a dilemma...

so what did you learn paul??? perhaps 'don't post stuff you don't know anything about or if you are not thinking straight'?
Actually, the puzzle requires some lateral thinking, so not strictly 'straight thinking'
