I'm really bad at these kinds of riddles:

Gr, I can't seem to find the answer to the sudoku....
So, sorry, no answer today.
Oh, I like this one, it tests lateral thinking skills:
A thief enters a shop and threatens the clerk, forcing him to open the safe. The clerk says, "The code for the safe is different every day, and if you hurt me you'll never get the code". But the thief manages to guess the code on his own.
How did he do it?

Answer to T3B12 coming tomorrow...
I've taken up a new hobby: sudoku. I used to hate it because I was
SERIOUSLY bad at it (like, seriously bad). I'd get to a point where I'd have
like two left in a row/column/square and I'd guess maybe one so I could keep
moving, get to the end of the sudoku, and realize that I have two 5's somewhere
or something. And I wouldn't know where I screwed up or guessed, and I'd be
like RRRAAAGGEEEE SPASM *ERASES ENTIRE GRID* *STARTS CRYING.... :'(* But then I
figured out this awesome strategy where you write all the possible combinations
in mini numbers above the grid, and it worked out fine-ish....
But recently, my aunt told me that she was hooked and that I
should try it because it improves you detail-noticing-skills, but I gave her
the rant about me being superbad at sudoku, and then I did a really easy one on
her phone, and I remembered that I actually liked doing math/problems when I
wasn't raging at them :).
So ta-da! Sudoku today! (Maybe I'm just really random and crazy
sometimes....)

It's soooo pretty but I bet it would be pretty cold.... and I'm sorry, unlike Elsa, the cold always bothered me...
Seriously, it'd be so cool to live in a huge palace, all made of ice... and it would be really pretty too, with the ice made into all sorts of shapes. Although maybe a palace of chocolate would be better.... ;) You could eat all of it!
I suppose someone who does live in such a palace would get pretty tired of seeing and eating chocolate.
How about a random riddle?
I actually really like this one because it is a complicated version of another riddle:
There is a strange island in the South Pacific called Haircut Island. The law on this island states that you cannot cut your own hair and you must get your hair cut once a week. There are no mirrors and only two barbers on Haircut Island. These two barbers are identical twins. One barber can't cut hair very well, but his brother rules. The locals refuse to tell you which of the barbers is the good haircutter. You need a haircutter really badly! How do you know which barber to pick for the good haircut?

The answer to T3B9:
Pour the lentils into the innkeeper's sack, bind it and turn inside out. Pour in the peas. Then unbind the sack a pour the lentils back to your sack.

Answer to T3B7:
The coins were fake. BC stands for Before Christ, so how could people know it was 400 years before Christ was born? The dating system of BC and AD arose some years after Christ's birth. (oh look! geeky fact!)
Answer to T3B8:
I don't really understand this, now that I read it more carefully...
The back prisoner will yell "black" if there is an odd number of black hats in front of him and "white" if there is an even number of black hats in front of him. The next prisoner will then count the number of black hats in front of him and if it was odd and is now even, or vice versa, then that person knows what color their hat is. The next person then knows their hat color based on what the people before them said and how many black hats are in front of them. In this way the front 99 prisoners will know their hat color and will be set free. The prisoner in the back who goes first has a 50 percent chance of being set free.
I just realized, what if you have, say 98 black hats in front of you and 1 white? And you have a black hat? Then you'd have to say "white" but you'd go to jail! And if the next person saw 97 black hats and 1 white, then he'd know he was a black hat. But he'd say "black" because... oh, I get it now.
Okay wait, what if you see 97 black hats and 2 white ones? You have a white hat, and you say "black". You go to jail. The next person sees 96 black hats and 2 white ones. He has a black hat. He says "white" and also goes to jail! The next person sees, say, 96 black hats and 1 white one. He says, "white". The next person sees 95 black hats and 1 white one. He says, "black".
Then you can only save 98!
Or if you have the same circumstances, but the second person sees 97 black hats and 1 white one? He has a white one, but has to say "black". The next person person sees 97 black hats and no white ones. He says "black" but knows he's white, and he has to go to jail! The next person sees 96 black hats and no white ones. "White", but he's wrong! This way, less than 50 people will be saved, because each person will have to alert the person in front of them and it will alternate--white, black, white, black. But they're all black....
I'm very confused now. Even after this long and crazy rant about this riddle. :(
I'll post the answer to T3B9 tomorrow... leave some more time to think... :P

Answer to T3B7 and T3B8 will be posted tomorrow...
How about another riddle?
A poor farmer went to the market to sell some peas and lentils. However, as he had only one sack and didn't want to mix peas and lentils, he poured in the peas first, tied the sack in the middle, and then filled the top portion of the sack with the lentils. At the market a rich innkeeper happened by with his own sack. He wanted to buy the peas, but he did not want the lentils.
Pouring the seed anywhere else but the sacks is considered soiling. Trading sacks is not allowed. The farmer can't cut a hole in his sack.
How would you transfer the peas to the innkeeper's sack, which he wants to keep, without soiling the produce?

I really like this one, because it requires creative thinking. Also, this would be a good thing to apply in real life (not with peas and lentils, but it is a good problem).
