(For those of you who like pretty things, this version has continuous spiral arms and the black hole consumes a single 7-hex tile at the end of every turn instead of huge swath of real estate at the end of every round.
Rules:
Black Hole: At the end of every TURN, roll a d20 to determine which type of terrain is pulled in by the Black Hole.
1-4: Grass
5-8: Sand
9-12: Rock
13-16: Snow
17-20: Road
(Note that Lava Rock is never pulled off. )
The outer-most 7-hex tile of the corresponding terrain type is removed from the map each time that terrain's number is up. Any units standing on those tiles are also removed from play, victims of the Black Hole. If the entirety of one terrain type has already been removed from the map, reroll the d20. The Black Hole must be fed!
