RIDDLE #1
Imagine a digital clock. How many times will the clock display three or more of the same number in a row over the course of one day?

In case you were wondering, the clock in this puzzle displays time on a 12-hour scale, not on military time.

RIDDLE #2
Ten candles stand burning in a dining room. A strong breeze blows in through an open window and extinguishes two of them. Checking back in on the candles later, you see that one more candle has gone out. To make sure no more flames go out, you shut the window. Assuming the wind doesn't extinguish any more candles, how many candles do you have left in the end?

RIDDLE #3
I am like a rock, but one word can break me. What am I?

RIDDLE #4
What does a white rock become when thrown into a red sea?

RIDDLE #5
What letter of the alphabet has the most water?

RIDDLE #6
Alfred and Roland have been hired by a farmer to sow flower seeds. They've been assigned a 10-acre plot of land and split it in half so they can work independently. Roland starts from the east and Alfred from the west.

Alfred can plow the land at a rate of 20 minutes per acre. Roland takes 40 minutes to plow, but sows seeds at three times the speed Alfred does.

If sowing seeds on the 10-acre plot pays $100, how much of that money should go to Roland?

That's enough for now, I may add more later if people like doing these!
