>What about games with 5, 7 or 11 players?

You're right. Unless you can find a reasonably small number that is divisible by all numbers 2 through 11, and 24 also, then an egalitarian fixed drop cannot be played for all the multiplayer possibilities on this site. 144 gets most of them. For 5, 7 and ...

My concept, is to have the ultimate battle-royale map, where luck is removed, and the outcome is decided purely on gameplay. Given the absence of any random outcomes (in the event of fixed drop and fixed dice), the winner of a game on this map would truly be considered the best Risk player.

In a 1v1 game, imagine the drop to essentially be a black/white checkerboard, with each player having their troops in the same order/arrangement as their opponent. Extend this to all the divisors of 144, and you can have multiplayer playing in the same manner.

I'm saying that rather than a random drop, a fixed drop can occur. So that everyone has the same "starting" position, which can mean their territories are scattered all over the map (just like regular risk) but because 144 is divisible by 4 (and 6 and 8 etc.), and the map is symmetrical everywhere ...

I'm a migrant from Major Command. I'm not particulary popular there (actually, extremely unpopular). This map proposal got no traction there, not even a single reply. Hopefully you guys see something here that they don't.

Map Name: The Ring
Mapmaker(s): missy_starlet
Number of Territories: 144
Special Features: Fully symmetrical about every axis. Will allow for the option of a "fixed" drop start, whereby every player has the exact same starting position as every other player. 144 is divisible by 2, 3, 4, 6, 8, 9 ...
