1. The 1971 rule book applies except where amended below.
2. Iceland (Ice), Ireland (Ire), Corsica (Cor), Sardinia (Sar), Sicily (Sic), Crete (Cre) and Cyprus (Cyp) all become neutral supply centres.
3. Iceland is adjacent to NAO and Nwg.
Ireland is adjacent to NAO and Iri.
Corsica is adjacent to GOL, TyS and Sar.
Sardina is adjacent to GOL, Cor, TyS and WMS.
Sicily is adjacent to TyS, Nap and Ion.
Crete is adjacent to Ion, Aeg and EMS.
Cyprus is adjacent to EMS.
4. There are now 41 supply centres. The victory condition is 21 supply centres.
Note: The initial scramble for neutral supply centres is much more balanced; no power should lose out in 1901.
Additional note by Richard Jackson, UKVB Custodian: It is a matter of opinion whether the last statement is correct. It has been suggested that by combining the Winter 1900 variant where there is an extra season for players to choose what type of units to start the game with, will produce a more evenly balanced game. If anyone decides to run this variant, the variant bank will appreciate endgame statements on its playability.
