Magic prevails during the Christmas holidays: the streets sparkle with bright lights, music resounds all over - children's laughter, too - and even adults start to believe in miracles again! Christmas is the best time for incredible adventures and travels! The Walkers were planning a little trip when Uncle Rat and Auntie Sheep turned up at their door. Cryptically, they handed them an envelope. Uncle said it was a humble gratitude for everything the Walkers had done this year. Sloth Walker rushed to open the envelope. Inside it were five tickets for a Christmas cruise! The whole family would travel around the world on a luxury liner! At every stop, they'd get to go ashore to admire the sights and then return to celebrate Christmas! What a fantastic gift! And, the most important part? The fifth ticket is yours! Join the Walkers on their amazing Christmas cruise to show your best skills, solve puzzles visiting cities around the globe and celebrate the best holidays ever! Come aboard!
