Featured Puzzle: Lighthouses #4

ByJacob Valdez

On this day in 1798, the US Congress commissioned the first federal lighthouse. Then, 200 years later, Ronald Regan created National Lighthouses Day on August 7th. Interestingly, this law made many lighthouse grounds open to the public.

Hidden somewhere in this grid are a group of single-cell tugboats. Can you use the clues provided by the lighthouses to find them all?

  • Lighthouses reveal all boats that share a row and column with it. Nothing blocks the lighthouse’s light.
  • Numbers count how many boats are revealed by that lighthouse.
  • Each boat is lit by at least one lighthouse.
  • No boat is adjacent to any other boat or lighthouse in any direction, including diagonally.

Happy Leap Day! Every four years, we make up for the fact that the solar year is about 6 hours longer than the 365 days on the Gregorian calendar. To do so, we simply add an extra day at the end of February. This was actually a major plot point in The Pirates of Penzance.

Today’s puzzle is Leapfrog. The Japanese name is Satogaeri, literally “coming home.” This is the first puzzle I’ve introduced in which you must visualize movement. Move the frogs so that each region contains exactly one frog.

Featured Puzzle: Meadows #2 – Black Cat Strut

Today is Black Cat Appreciation Day! Did you know that black cats wait an average of 2-3 days longer to be adopted, because of superstition? It’s a shame, and I can attest to their delight, since I’ve had several pblack cats keep me company throughout my life.

Now, we know that cats are territorial, so today we’ll theme a Meadows puzzle. Simply divide the grid into squares, each containing a single black cat.
