Lost Worlds will take you on a treasure hunt into three ancient worlds: Rome, Egypt and MesoAmerica (Mayans). You have 60 levels of reflexive games like Spot the Differences, Trivia, Hidden Objects or Built-it Puzzles. Completing a world can unlock bonuses and puzzles of another world. When trying to solve a puzzle, you have to do it in a certain time to earn more bonus points.
Being a History Channel product, the game is based on real pictures and provides information on the three civilisations you have to explore.
