Most likely it is wolfpacking - kindly send a ticket ingame and we will check it out by looking at players and their communications.

Well here's whats wolfpacking according to the rules
"Forming groups of Users in Dorado Games or Services beyond the applicable group limits (Wolfpacking) with the sole reason of gaining added benefits or tipping the balance of the Games in favor of the Users. Often this behavior is accompanied by deliberately making the experience miserable for new or less experienced Users (Ganking). ALLIANCE CAP: Alliance members belonging to the same Alliance are not allowed to join the same game beyond the coalition limit for said map (GameID). Currently, the Wolfpacking rule means the following:
Players that join the game with no intention of playing skillfully, and instead assist another player only to leave once the damage is done. For example, player X invites player Y to join. Player Y sends all his units to a neighboring nation only to close the game. The breach rule here is that the sole intention of joining was to take up a slot, and make the game easier for another player."

So two random coalitions working together is just fine

you can look if they're all from the same alliance, otherwise you really cant... but easiest way would be to just let support check it by sending an ingame report

you need to, a- give game id number here or-b do in game bug report because they can check what the flags were previously.

secondly go to game info then click the info icon on these particular players this should tell

i got a question for the devs on wolf packing there been talk about coalitions having sub-alliances and i myself have been in the past on a map had two different coalitions working together, this in general isnt an issue it is when they are from alliances and you suspect they might be getting around wolf packing by saying they different alliances when in reality their not.

we need a list of alliances who have sub alliances to ensure unfare game play is not happening
