🧩 Puzzle XL Contest Starts June 18! 🧩

Prepare for our annual Puzzle XL event, kicking off on June 18!
This special contest features 13 extra-large puzzles, each set on grids much larger than our regular daily challenges. A brand-new XL puzzle will be released every day, bringing fresh twists and bigger challenges that may take a little more time—and space—to complete.
📱 Please note: Because of their larger size, these puzzles may be more difficult to solve comfortably on mobile devices.
Take on the challenge, put your puzzle-solving skills to the test, and see how high you can climb on the leaderboard. Good luck, and happy puzzling! 🎯
