Each player may draw one of ten "variants". Many of these were minor amendments to the force pools, e.g. extra French armor units instead of the Maginot Line. Two of the German variants were potential game-throwers, allowing Spain (and hence seizure of Gibraltar and transfer of the Italian fleet to the Atlantic, prior to invasion of Britain) or Turkey to join the Axis. The fourth edition diluted the chances of this happening by adding an extra 10 for each side, including "Hitler Assassinated" (requiring Germany to pass for a turn, with a chunk of her BRPs frozen).
