Rolling World

Rolling World, based on the 2014 release Rolling Japan, is a light "multiplayer solitaire" dice game. Each player has a map of the world that's divided into regions, which are then bunched together into six differently colored areas.

On a turn, a player draws two regular six-sided dice from a bag and rolls them; the bag starts with seven dice, six matching the colors of the areas on the map along with a wild gray die. All players now write down each number rolled on any state of the matching color, i.e., if the blue die shows 4 and the yellow a 2, write a 4 in one blue state and a 2 in one yellow state. If the gray die is rolled, you can place this number in a state of your choice; additionally, three times per game you can choose to use a non-gray die as any color. However, neighboring states can't have numbers with a difference larger than 1; if you can't place a number without breaking this rule, then you must place an X in a state of the appropriate color. (If all the states in an area are filled, you can ignore the die or use one of your three color changes to place the number elsewhere.)

After six dice have been rolled, mark one round as being complete, then return the dice to the bag and start the next round. After a number of rounds the game ends, and whoever has the fewest Xs on their map wins.
