Puzzle 139

 * Name: Coast to Coast
 * Picarats: 70

Description: A woman boards a nonstop flight leaving Los Angeles at noon and arrives in New York City at 8 p.m. The next day, the same woman leaves New York at noon and flies back to Los Angeles. The flight is unaffected by jet streams and takes the same amount of time to reach its destination as it did the previous day. The time difference means it is always three hours earlier in New York than in Los Angeles. Can you figure out what time the plane arrives back in Los Angeles? Give your answer in 24-hour notation.


 * Hint 1: Think about the rotation of the earth. The time in locations farther to the east is ahead of that of more western locales. Therefore, given a three-hour time difference, when it's noon in Los Angeles, it must be 15:00 in New York.
 * Hint 2: Taking into account the time difference, the plane left Los Angeles at 15:00 New York Time and landed at 20:00. Therefore, the flight itself must have taken five hours.
 * Hint 3: The time difference has a reverse effect on the flight returning to Los Angeles. If the plane to Los Angeles left New York at noon New York time, you could also say it left New York at 9 a. m. Los Angeles time.

Puzzle 140

 * Name: One Extra Block
 * Picarats: 70

Description: The diagram below shows a structure made of 28 blocks. Of these blocks, 27 form a neat larger cube, and on top of that sits a single block poking out above the rest. Below this diagram sit those same 28 blocks, but this time the cube had been separated into five chunks. Tap the chunk, A through E, that contains the single block that sat on top of all the others. Assume that all five chunks fit together as shown and can't be rotated from their current orientation.


 * Hint 1: If the top block on chunk D were the block you're searching for, then the block on the bottom-left corner would stick out of the cube. D must not be the correct answer. Remember, each chunk is locked in its current orientation and can't be rotated.
 * Hint 2: If the block you seek was at the top of C, then D would be forced out of the structure when all the chunks were put back together. Chunk C must not be the answer either.
 * Hint 3: Chunk D forms a part of the front-left side of the large cube. Use that information to start reconstructing the structure in your head. As the pieces come together, the answer should be clear.

Puzzle 141

 * Name: Disappearing Act 6
 * Picarats: 99

Description: Just as before, you can move any ball in the board below just as long as it satisfies the following conditions: OK enough rules, start getting rid of those balls!
 * To move, jump your selected ball over an adjacent space occupied by another ball into an empty space on the other side. You can't jump diagonally.
 * Once you've made the jump, the ball you jumped over disappears from the board.
 * To complete the puzzle, you must remove all balls from the board except for one.


 * Hint 1: You have quite a few balls to get rid of, so you'll have to do a lot of jumping. Just make sure you aren't choosing your moves at random, or you'll end up getting stuck before you finish. Plan out your jumps so that you never leave any balls out away from the group where you won't be able to reach them later.
 * Hint 2: As you reduce the number of balls on the board, those remaining take on a configuration that you've previously solved. If you've made it this far, this puzzle is in the bag for you.
 * Hint 3: Sorry, there are no more hints to be had for this puzzle, You may have heard that proper peg solitaire players don't consider these puzzles complete unless the remaining ball ends up in the center space. One step at a time, though. Let's finish this puzzle first.
