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.
