Timmy, who is a gambling addict, enters a casino with $50 at 7:00 PM. He loses $20 in his first five minutes, but in the next five minutes he is able to make $15 of it back. He loses $20 more in his third five minutes, wins $15 back in his fourth five minutes, and so on in that cycle. At what time will he run out of money?
He ran out of money at 8:05.
At 8:00, he had $20. He lost it by 8:05. You can't regain money if you have none to start.

Agh! Sorry for being so late. I was out. Anyhoo, lets start with a classic, just cuz I'm too tired to think...
You are traveling by foot to a shop in the City of Truth, where everybody tells the truth. You reach a fork in the road. You know the City of Truth is one way, but you don't know which. You also know that the City of Lies, where everybody lies, is on the opposite side of the road as the City of Truth. There are two children standing at the fork. You can tell that one of them is from the City of Truth, and one is from the City of Lies, but you cant tell them apart. You can ask them one question. What would be the best question to ask?
Sorry for unoriginality and possibly awkward wording, but I'm already late enough as is

Not accepting defeat, the hat-king sets up yet another challenge for his 100 wise men. He escorts them all into a dark room where half of the men are given red hats, while the other half are given blue hats. The room is pitch black, and no one can see anything. The king then tells them that he is standing next to a door. On the other side of that door is an illuminated room. The king challenges the men to enter the illuminated room one by one and form a line with all their hats alternating colour (Red, Blue, Red, Blue, Red, Blue, Red). However, once they are past the door, they may not return to the dark room, touch each other, or communicate in any way. The king gives the men time to devise a plan in the dark room. When eventually, much to his surprise, the men walk through the door one by one and form the line he challenged them to make. What was their plan?
Divide each number into separate digits. If the same digit occurs twice in a row, group them together. The state how many of each digit there are.
(eg
1113122112
111 3 1 22 11 2
"There are three ones, one three, one one, two twos, two ones, and one two."
311311222112)
