Soron, if you think that map is big you are in for a BIG surprise when you play the next challenge (Europe)

Or just check out this monstrosity:

@RvW - It's a little different. The opponent can reach into a bonus that's much farther away than just being adjacent to the bonus. For instance, say you have the India Bonus. Someone could attack into it from several more spots than before. You also have the tendency to run into other opponents easier because everyone is trying to get to their bonus a different way.

This of course is coming from experience of playing the settings in a large FFA game

Holy... I saw the Europe Challenge map, and frankly, the idea of a team battle shocked me more than the map itself. I still have yet to read the Wiki. But over 3100 territories! I am literally afraid of that map!

Well, so I don't look like a troll, I'll put something related into this post. It would be beyond awesome if this idea was incorporated into Europe or United States Big!

perhaps if it becomes popular enough, fizzer could create a setting which would allow it to be done on any map, as opposed to being forced to re-work maps for it to work..

I think a mirror earth hopscotch hybrid is in order.

Knoebber that.. would be incredible fun and mind numbing..

Mirror version where everything is attached to the territories adjacent to it's mirror? Sounds fun.

Tip:
Select an important territory (such as an enemy's on your border), then click the "More Info" link in the menu on the left. This will give a nice overview of which territories "border" on the selected one *and* (if you're in deployment phase), you can just click territories in the territory info window to deploy extra armies there! :)

Okay, the one that first finds out what´s the least amount of turns you´ll need to complete the South America bonus gets a cookie. Starting with only one territory somewhere inside South America.

Moros, I think the answer is 8 attacks. To do this, you have to either start or end on Brazil and you have to leave SA once.

Argentina - Venezuela - Bolivia - Colombia - Paraguay - Peru - Uruguay - Siple (Ant) - Brazil

This is awesome and hurts my brain. I can't even start to figure out where is a good place to start.

Okay, I should have said you have an infinite number of armies and can attack multiple territories at once,

I don't think it would hold true for all starting points, but if you started in Bolivia it would take two rounds of attacks.

Attack 1 -> Venezuela, Colombia, Uruguay, Siple
Attack 2 -> Peru (Venezuela or Uruguay), Brazil (Siple), Paraguay (any)

Would need 17 armies on the first round (4 per for good odds) and then 10 or so next round (restock up to 16 attackers). So long as you don't start in Brazil or Argentina it you would be fine (they would require 3 turns of attacks)

Richard, you must attack Nigeria too in the first round to get Argentina, but except for that you're correct (You'll get that cookie later =))
Okay, now the next mathematical question: is there any bonus on that map you'll need more than 2 turns for to complete?

@Moros - are you assuming being able to start in any spot or utilizing one or either of the distribution modes. With the Warlords distribution mode, East China would require 3 moves in order to get Taiwan.

Also, do you have to start in the territory you want to take in 2 turns? It actually looks easier to take a territory adjacent to the one you start in.

All bonuses are possible to take in 2 turns if using full distribution. (Assuming Neutrals are all 0)

East Russia: Start at Irkutsk.
Turn 1: Invade Inner Mongolia (W. China, for Mys Lopatk/Magadan/Zigansk), Karbarosk (for Anadyr/Kamchatka), and West Siberia. (for Chita)
Turn 2: Invade the rest of East Russia. (East Siberia is taken from Irkutsk, but is not needed for territories.)
{Anadyr also works if you don't want to bother West China, though you do take Japan)

Antartica: Start at Mawson/Halley/Russkaya.
Turn 1: Take the two territories you didn't start with that are listed above, and a territory outside the bonus for the South Pole.
Turn 2: Invade the rest of Antartica.

Greenland: Start at Nuuk/Danmark Havn.
Turn 1: Take Qaanaaq and Iceland.
Turn 2: Invade the rest of Greenland.

Most other ones are a bit more simplistic... For Europe, try Italy. For Canada, try Ontario. For East US, try Eastern Great Lakes.

Warlords is a different story, though most seem possible in 3 moves.

Moros, Argentina can be taken from Venezuela in attack 2. Just forgot to list it. No need to go outside of SA for it.

As for Warlords...

West US takes 3 turns, since Great Plains cannot be reached in 2 turns.
Scandinavia takes 3 turns, since Svalbard cannot be reached in 2 turns.
East Russia takes 3 turns, since Kamchatka cannot be reached in 2 turns.
East China takes 3 turns, since Taiwan cannot be reached in 2 turns.
Indonesia takes 3 turns, since Malaysia cannot be reached in 2 turns.
Australia takes 3 turns, since Western Australia cannot be reached in 2 turns.
Antarctica takes 3 turns, since Scott/Siple/Novo. cannot be reached in 2 turns.
All other bonuses are able to be taken over in 2 turns.

For Cities, every area is possible in 2 turns.

(I should probably play this map instead of just examining it.)

I definitely think the map needs bonus adjustments, although I'm far too much of a rookie to give major suggestions.

One thing I did notice that's a pretty huge change though, the East Africa bonus can be completed in 1 turn on warlords distribution, if you get both Ethiopia and Cameroon as picks. not sure how it would affect other distribution modes, but I would think that bonus should be decreased.

If you get Great Basin and Panama you can take Central America on one turn as well.
