Dice Trip: Switzerland

From BoardGameGeek:

Travel the country in Dice Trip: Switzerland, ideally hitting as many cities as possible while dressing in the right colors. In the game, you take a map of Switzerland that shows 25 cities, with each city being connected to a few others by dashed lines and with eight of them being colored in one of four colors; these colors match the colors of the four dice in the game. On a turn, you or another player roll the four six-sided dice, then each player uses the results to create two two-digit numbers, writing each number into an empty city. If you write a double-digit number (11, 22, etc.), then mark off a bonus box; if you fill, say, a blue city with a two-digit number that used the blue die for one of the digits, mark off a bonus box. You can write each two-digit combination (11, 12, 13, 14, 15, 16, 21, 22, etc.) only once, marking them off on the bottom of the sheet as the turns pass. If you can't mark off one or two cities based on the die results, then you must place an X through one or two cities. You have two special powers you can use once each game: re-rolling 1-4 dice when you're the active roller, and re-using a digit on one die in each of the two-digit numbers you create that turn. After thirteen turns, the game ends. You score 1 point for each marked bonus box and -1 point for each X. If you have four or more cities in consecutive order, e.g., 15, 16, 21, 22, 23, then you score 2-9 points based on the length of the chain. You also identify your longest chain of non-X cities that are in increasing order and score 1 point for each city. Finally, you score 0-9 points based on how many of the three zones have no Xed cities. Whoever has the highest score wins.
