Fewer troops, easier opponents? Doomsday matchmaking explained
Your alliance wants you to dismiss troops for easier opponents? Read what IGG's rules establish and four questions to ask before losing part of your army.
Published · Updated
Do not dismiss troops solely because someone promises an easier opponent. First separate your alliance's actual readiness from a convenient Strength figure. Our alliance participation guide covers that foundation. Here, we ask a narrower question: what do official Doomsday rules establish about choosing opponents, and what remains unproven?
The starting point was a player's Reddit question: their alliance had suggested reducing other troop types to improve matchmaking. Replies offered different calculation theories, but the discussion does not reveal IGG's algorithm. Remove the extras and it gets easier is advice to examine before applying it to your army.
Three questions that are easily confused
Eligibility asks whether you can participate. Ranking asks how you are ordered. Matchmaking asks who you will face. A change to one measure does not explain the other two.
For example, in version 1.53.0, IGG tied registration for Archipelago Raid, Island Raid and Jungle Crisis to the number of genuinely active members. That is an eligibility rule, not a published opponent-selection formula.
If an officer shows your alliance's position on a list, ask what that list measures. A lower position and a more convenient next match are different results. A screenshot of the first does not confirm the second.
Total Might is not the whole ranking measure
The notes for version 1.57.0, dated 26 May 2026, name Archipelago Raid, Island Raid and Extreme Showdown: ranking by Alliance Total Might was replaced with Alliance Overall Might. According to IGG, Overall Might considers both total alliance Might and recent kill performance. The relative weights are not given.
Open point seven at full size. The distinction matters: this passage concerns ranking. It does not reconstruct the full pairing algorithm. You cannot promise easier opponents after troop dismissal, nor conclude that troop numbers definitely have no effect. Neither claim has enough evidence here.
Pompeii separately mentions winning and losing streaks
Version 1.61.0, dated 28 September 2026, has a separate point about The Recovery of Pompeii: matchmaking adjustments after winning or losing streaks were to become more pronounced. The developer describes the aim as fairer matches. Neither the streak length nor the exact formula is disclosed.
Open point 6.2 at full size. Do not extend it to every cross-server event. Pompeii also has its own map fog and Apex eligibility rules. Neither a hidden map nor a league name explains how an opponent was selected.
What to ask an officer before dismissing troops
Start with four short questions. Everyone does it is an observation, not yet an instruction for your account.
1. Which exact event and cycle are we discussing? Ask for the full name and current rules. New matchmaking alone does not identify the relevant update passage.
2. What are we changing, and on what basis? Ask the officer to name the measure and show the rule or support response. Separately check whether the claim concerns eligibility, ranking position or pairing.
3. What establishes the link to the result? One favorable match after reducing an army does not isolate troop numbers from lineup changes, match history or other factors. If observations exist, compare their conditions and record what remains unknown.
4. What will it cost you? Before confirming dismissal, record troop types and counts, read the action warning and assess rebuilding under your own conditions. Another player's cost or recovery time is not a universal standard.
A practical next step
Save the specific event rules and current army composition. If there is no primary explanation, ask support a narrow question: whether this measure affects matchmaking in this particular mode, and when it is recorded. You do not need the secret formula to clarify the condition on which the advice depends.
Do not take an irreversible action merely to test a rumor. The goal is a clear basis for your decision, not a universal way to lower Strength. Without that basis, the promise of an easier opponent remains an assumption.
