Hexa Islands
Hexa Islands is a puzzle invented by László Mérő (Hungary) in 1999 under the original name Honey Islands. It was first presented in a single-puzzle round at the World Puzzle Championship 1999 (WPC 1999 / Part 7).
The puzzle is played on a hexagonal grid and follows the general idea of island-formation puzzles. However, Hexa Islands is notorious for its difficulty from a logical standpoint. Most puzzles of this type are extremely hard to solve using pure deduction and typically require guessing followed by correction. Verifying the uniqueness of a solution by hand is especially challenging.
Due to these difficulties, the original WPC round itself contained several puzzles that were later found to have multiple valid solutions, making Hexa Islands a historically notable but logically demanding genr
