Wall of Ice Diplomacy:
 
Variant Rules:

1.  At the beginning of the game, the map is standard.

2.  Each year, certain provinces lose Supply Center status, while others
gain it. This would be done by the GM from a list, but would be
somewhat  randomized, per the table which follows. The change in status
would occur after fall retreats of the year indicated, so that units
located on a province which gains Supply Center status would earn that
owner a build.

3.  Certain water provinces become impassable to fleets, due to
icebergs.  This would also occur after fall retreats and would also be
randomized per the table.  Fleets located in bodies of water which are
designated impassable are disbanded.

4.  Fleets may be converted to armies during adjustment turns.

5.  Builds may be made in any owned Supply Center.

6.  Winner is the owner of Tun and NAf.  The only non-win possibility is
a two way draw, as you will be able to figure out from the table below.

7.  The game can be played either with the slight randomness or
without.  For a game with exact changes in the supply center status and
water province passability, the changes always occur at the time a 75%
chance of conversion is indicated on the table below.
