Every year in mid-March, St. Patrick's Day is celebrated in Ireland. Here it is an official public holiday. But besides these places, the holiday has spread almost to this world, and now it is merrily celebrated in Canada, Argentina, the USA, New Zealand and Australia. And in the British kingdom even the water in the fountains is made green. Cheerful parades are held everywhere and the green color is especially popular. This is due to the main character of the leprechaun, who wears a green camisole and a hat. You will meet this interesting character in the game Saint Patrick's Day Sliding Puzzles, collecting puzzle fifteen.
