0. Regular Diplomacy rules apply except when they don’t.
1. The game begins in Winter 1900 which is played as a separate season.. Players may decide which type of unit to build in their home centres in readiness for Spring 1901. Russia may build F(StP)nc if it wishes.
2. Any army in a coastal province may, instead of being ordered to move or support, be ordered to turn into a fleet. Such a transformation will be successful provided the unit is not dislodged that move.
3. Rising sea levels result in the gradual submergence of provinces according to Table 1 below. Submergences occur every year after any adjustments in Winter. Once submerged, a s.c. is effectively destroyed and may not be used for the following Winter’s adjustments.
Table 1 – Submergences
W 1901: Lon, Hol, Bel, Gas, Ven, Lvn.
W 1902: Yor, Pic, Apu, Rum, Sev, Fin, Syr, Den, Lpl.
W 1903: Arm, Bre, StP, Par, Tus, Nap, Bud, Kie.
W 1904: Ber, Mos, Mar, Por, Rom, Vie, Bul, Gre, Pru, Ruh, Gal, Ukr, Con
W 1905: Wal, Cly, Swe, Tri, Alb, War, Ice
W 1906: Edi, Spa, Tun, Ser, Smy, Sil, Boh.
W 1907: Nwy, Mun, Pie, Tyr, NAf, Bur, Ank.
4. Armies in provinces which submerge are drowned!
5. New supply centres are formed in the course of the game, after all Winter retreats and adjustments, according to Table 2.
Table 2 – New Supply Centres
W 1902: Wal, Ruh, Tyr.
W 1903: Ukr, Ice
W 1904: Pie.
W 1905: Boh, Sil.
W 1906: Swi
W 1907: NAf
When a new s.c. is created it immediately comes under the control of (1) any unit occupying that province, (2) the last country to have a unit in that province (spring or autumn), (3) the country within whose boundary the new s.c. lies or (4) if none of the above it is neutral.
6 Iceland is a valid space in this variant and it becomes passable after W 1901. The province of Switzerland becomes passable after W 1904.
7. Players may build units in any vacant supply centre which they control.
8. All Abstraction A/F convoy rules apply.
9. The winner is the survivor (if any) after W 1908.
The main changes from the original Deluge are (1) variable Winter 1901 placements; (2) addition of Iceland as a space and centre; (3) Con sinks a move earlier than in Deluge I; (4) confirmation that armies in sinking spaces drown, but flexible rules to allow the conversion of armies to fleets (but not vice versa); (5) builds can be taken in any vacant owned centre.
