The challenge isn't the big names. Around Fort Worth, Arlington, Irving, Plano, Grand Prairie and Richardson sit shoulder to shoulder, so every inch counts. Along the Gulf, Galveston and Baytown ask for the same precision, while Midland and Abilene test your sense of distance further west. Each round asks 20 of the 151 cities, with 15 seconds per city. The closer your point is to the real spot, the more points you earn, and a time bonus rewards speed. Play it often and you will see the shape of the state, its clusters and its distances, much more clearly. A good workout for travelers, students and sports fans.
