Featured Puzzle: Fold-a-Box #1
When I was a kid, origami was a hobby I delved into with a passion. All these years later, and I just discovered that November 11th is World Origami Day! Today’s puzzle, originally named Yokibunkastu (“container dividing”), is themed around folding, so I thought it would be appropriate for the occasion. Draw walls to form pentomino (5-cell) regions around the paper cranes.
Featured Puzzle: Fold-a-Box #2
Boxing Day is celebrated in many countries around the world, usually the day after Christmas. Originally, it was the day that alms boxes were opened, and the contents distributed among the poor. Today, some of that spirit remains, but it’s also a shopping holiday similar to Black Friday. Naturally, it seemed a good fit for a Fold-a-Box puzzle. Draw walls to create pentominoes to box up the various gifts.
Featured Puzzle: Meadows #1 – Isolate the Shamrocks
Saint Patrick was a fifth century Christian missionary in Ireland. Interestingly, he was actually British, kidnapped by pirates and held as a slave in Ireland for 6 years before escaping. Later, he returned to proselytize. Another fun bit of trivia – the four-leaf clover is not a shamrock. A shamrock has only 3 leaves, and Saint Patrick used it during a sermon to illustrate the concept of the Holy Trinity.
Today, we’re playing Meadows. Simply divide the grid into square regions. Every region must contain exactly one four-leaf clover.
