The game mixes four worlds: seas and straits like the North Sea and the English Channel, rivers like the Rhine and the Tiber, islands like Gotland and Rhodes, and mountains like the Sierra Morena, the Jura Mountains and the Sudetes Mountains, plus gulfs like the Gulf of Finland. Each round asks 30 of the 176 landmarks, with four minutes for the whole game and three attempts per question. Each wrong attempt costs points, and the time left at the end earns a bonus. Because only a part of the landmarks come up each time, every game looks different. A good exercise for school, hikers and anyone who loves maps.
