CWL format explained: sign-up, roster pool, war days, scoring
CWL has three layers you must understand as a leader:
1) The roster pool (the “sign-up roster”)
During CWL sign-up, leaders choose a roster pool that can be as small as the minimum requirement or as large as the full clan. Only players in that roster pool can be selected into daily wars.
2) The daily war lineup (the “today roster”)
Each war day, you pick your actual lineup: 15 or 30 players (depending on war size). People not selected that day still can help with donations and planning, but they won’t attack that day.
3) The group and scoring system
- Your clan is placed in a group and fights one war per day during war week.
- Clan ranking is based on total war stars across the week, with total destruction used as the tie-breaker.
- Winning a war also gives your clan an extra stars boost that matters a lot in tight groups.
The most important CWL truth:
You don’t “win CWL” by having the best player. You win CWL by having the fewest bad attacks and the fewest missed hits across the whole week.
CWL leagues in 2026: new tiers at the top
In 2026, CWL expanded at the top end with new higher leagues that spread competition more evenly and create a clearer climb path. The big headline is the addition of new tiers above the previous ceiling, including Titan III, Titan II, Titan I, and Legend.
What that means for clans:
- The “top end” is less compressed, so promotions can feel more natural.
- Rewards across leagues were rebalanced to account for the new tiers.
- Battle Modifiers exist in some of these top leagues, which changes how offense and defense perform compared to lower tiers.
If you’re not near the very top, don’t ignore this—because expansion affects the whole ladder. When the top stretches out, movement and balance ripple downward over time.
15v15 vs 30v30: choose the right war size for your clan
Picking the wrong war size is the fastest way to sabotage your CWL month.
When 15v15 is the best choice
Choose 15v15 if:
- You have 15 reliable attackers who will show up daily.
- You want to push league promotions more aggressively.
- Your clan has a top-heavy roster (a strong top 15, weaker bench).
- You want simpler planning and less daily chaos.
15v15 rewards:
- Strong coordination
- Higher average skill per attacker
- Cleaner matchups inside your own roster (less “who do we sit?” debate if your rules are clear)
When 30v30 is the best choice
Choose 30v30 if:
- You have 30+ active players who can attack daily.
- Your clan goal is more participation and more medal spread, not only promotion.
- You’re building a long-term clan culture and want people to feel included.
- You have a wide skill range and want to develop more hitters.
30v30 rewards:
- Participation and loyalty
- Faster improvement for developing players
- More flexibility to rotate, rest, and still field a full lineup
The practical decision rule
If your clan misses attacks sometimes, do not choose 30v30 unless you have strong leadership systems.
One missed attack hurts more in CWL than almost anything else.
Roster building system: how to create a CWL lineup that wins
A winning CWL roster is not “our strongest accounts.” It’s our most reliable system.
Step 1: Define your CWL goal before you choose players
Pick one primary goal:
- Promotion push: strongest + most consistent lineup, tighter selection
- Medal farming: maximize participation while still staying stable
- Development month: rotate more, accept slower results, focus on learning
Write it in clan mail before CWL starts. When everyone knows the goal, drama drops.
Step 2: Build your CWL roles
Every clan needs roles. This is what “system” means.
Role A: Anchor hitters (the stabilizers)
- Usually your best and most consistent players
- Their job is not always triple—it’s to prevent disasters
- They often hit the toughest bases or the bases that decide the war
Role B: Secure hitters (safe 2-star specialists)
- Players who may not triple everything but rarely fail
- Their job is to turn “risky matchups” into guaranteed points
Role C: High-ceiling hitters (triple hunters)
- Players who can triple, but sometimes miss
- Their job is to take smart triple attempts when the plan supports it
Role D: Cleanup + time management players
- Players who are fast, reliable, and rarely time fail
- Their job is to finish wars cleanly and protect destruction tie-breakers
A clan that assigns roles wins more than a clan that just “lets people attack whoever.”
Step 3: Decide your TH mix strategy
Because CWL matchmaking is league-based, you can face clans with different Town Hall distributions than yours. Your TH mix strategy should be intentional:
- If you’re top-heavy (more max accounts), focus on clean 3-stars at the top and minimize risk below.
- If you’re bottom-heavy (more mid accounts), focus on safe stars and protect destruction.
- If you’re mixed, run a “two-layer plan”: top aims for controlled triples; mid aims for safe 2-stars; bottom aims to avoid 0–1 star outcomes.
Step 4: Pick a bench that keeps the clan stable
Even in 15v15, you want backups for:
- Time zone issues
- School/work days
- Hero upgrade conflicts
- Tilt (someone mentally off after a fail)
A “bench plan” prevents missed attacks and reduces pressure on your core lineup.
CWL prep week: the 7-day checklist that makes CWL easy
The easiest CWL weeks are built before CWL starts.
7 days before CWL
- Announce your war size (15 or 30)
- Announce your roster rules (who plays, rotation policy, missed attack policy)
- Ask everyone to mark war preference correctly
- Identify hero upgrade conflicts (who will have heroes down)
5 days before CWL
- Choose 2–3 main attack styles your clan will focus on (don’t allow 20 different armies)
- Run friendly challenges to test funnels and spell timing
- Lock in donation standards (what defensive Clan Castle troops you’ll use)
3 days before CWL
- Confirm who is active daily
- Confirm time windows (who attacks early vs late)
- Confirm backup players
- Set your war map communication method (calls, assignments, or simple “claim your mirror” rules)
1 day before CWL
- Final reminder: “one attack per war day—no missed hits”
- Confirm everyone has at least one reliable army trained
- Confirm war base layouts are updated and traps are placed
Prep is not exciting, but it’s the reason strong clans look “effortless” during CWL.
Base prep system: how to reduce free triples
In CWL, defense is not about being unbreakable. It’s about being annoying:
- Force awkward pathing
- Force bad spell value
- Waste time and cause small mistakes
CWL base rules that work in every league
- Don’t stack your most valuable targets where one spell combo deletes them
- Protect your core from straight-line entries
- Place traps to punish the most common entry angles in your league
- Avoid “obvious” funnel value on both sides of the base
War map discipline
Make sure everyone understands:
- Base swaps are not random. If someone’s base is being farmed for triples, it needs a rebuild.
- Small edits matter: a trap shift, a defense reposition, a slightly different funnel shape.
Your goal isn’t “never get tripled.” Your goal is “make triples harder and slower.”
Attack planning system: how to maximize stars with one attack
Because CWL gives one attack per day, your clan needs a rule for choosing attacks:
Rule: secure points first, then chase extra points.
That means:
- If a player is uncertain, they should take the safe 2-star.
- If a player has a strong plan and practice, they take the triple attempt.
- If a player is tilted or rushed, they take the safest reasonable hit.
The “Three outcomes” approach
For every attack, decide which outcome you’re targeting:
- Outcome 1: Guaranteed safe stars (minimum risk)
- Outcome 2: High percentage + strong stars (balanced)
- Outcome 3: Triple attempt (higher risk, higher reward)
Clans that win CWL know when to choose each outcome.
War-day operations: the daily routine that prevents chaos
This is the simplest “winning system” you can implement.
War-day timeline (copy-paste routine)
Early window (first 3–6 hours of battle day):
- Leaders assign targets or confirm mirror rules
- Players with tight schedules attack early
- Any scouting notes are posted immediately after attacks
Mid window:
- Adjust plan based on early results
- Shift targets if an enemy base proves stronger than expected
- Identify “must secure” attacks vs “triple opportunities”
Late window (last 3–4 hours):
- Finish remaining hits
- Prioritize safe stars and destruction
- No experimental armies, no “first time trying this” attempts
The #1 CWL killer: last-hour panic
Last-hour panic creates:
- Missed hits
- Rushed attacks
- Wrong donations
- Emotional mistakes
A system fixes this: assign times, assign priorities, and keep a rule that prevents procrastination.
Scouting and target selection: how to win without being stronger
Your clan does not need to outpower opponents to beat them. It needs to out-plan them.
Simple scouting questions
- Which enemy bases look like “free triples” for your best hitters?
- Which enemy bases look like “trap bases” that could cause fails?
- Which enemy bases are spread, and which are compact? (This affects army choices.)
- Where are the obvious entry lanes? (Don’t attack exactly where they want you to.)
Target calling systems (choose one)
System A: Mirror + flex
- Most players hit mirror
- Top hitters have permission to shift if a better triple exists
- Leader approves any major changes
System B: Assignment board
- Leader assigns targets
- Everyone follows the plan
- Best for serious push clans
System C: First claim
- Players claim a target in chat (with a time limit)
- If not attacked within the time limit, the claim expires
- Best for semi-casual clans that still want structure
Whatever you choose, consistency matters more than perfection.
Rotation system: include more players without losing wars
Rotation is how you grow a clan. But rotation without structure is how you drop leagues.
Rotation rules that work
- Rotate only players who can attack reliably that day
- Don’t rotate out your entire top core on the same day
- Use rotation to manage hero upgrade conflicts:
- If someone has heroes down, bench them on days you expect the toughest wars
- Put them in on days you expect easier opponents
Fairness rule that prevents drama
Announce rotation policy before CWL starts:
- “Top performance plays more” (competitive model)
- “Everyone gets X wars minimum” (community model)
- “Rotation depends on activity” (reliability model)
Pick one. Communicate it. Stick to it.
League Medals system: how rewards actually work
CWL medals are the long-term engine of your clan’s progression. A smart clan treats medals like a monthly budget.
How full medal rewards are earned
Players earn a share of medals based on participation and stars. A key threshold is that players typically need around 8 stars across the week to receive full individual reward scaling in many setups. This is why rotation must be planned carefully—if you rotate too much, some players may not reach the threshold and will feel punished.
Bonus medals: the leadership tool that builds culture
Leaders and co-leaders can award bonus medals at the end of CWL. This is not just a reward system—it’s a culture system.
Best bonus medal policies
Choose one policy and publish it:
Policy A: Performance bonuses
- Award bonuses to top star scorers and highest impact hits
- Best for competitive clans
Policy B: Reliability bonuses
- Award bonuses to perfect attendance, early attacks, and clean safe hits
- Best for clans trying to eliminate missed attacks
Policy C: Growth bonuses
- Award bonuses to most improved attackers or best learner
- Best for development clans
Policy D: Mixed
- Half the bonuses for performance
- Half the bonuses for reliability/culture
- Best for most clans
The worst bonus policy is “vibes.” Vibes create arguments. Rules create trust.
CWL 2026 winning strategy: climb leagues with repeatable systems
Here are the systems that consistently move clans upward over multiple months.
System 1: The “No Missed Hits” contract
- Missing a CWL hit is treated as a serious mistake (because it is).
- The rule doesn’t have to be harsh, but it must be clear:
- If you can’t attack today, tell leadership early
- If you miss without warning, you sit the next day (or next CWL)
This single system wins wars.
System 2: Two armies only (per Town Hall bracket)
Most CWL fails happen because people swap armies constantly.
Give your clan two options:
- Army A: safest, most repeatable
- Army B: higher ceiling for certain base types
Let people master these, not chase trends.
System 3: “Secure first, then greed”
Early in the day, secure reliable stars. Late in the day, if you have room, chase triples.
This prevents the classic CWL throw:
- everyone tries crazy triples early
- clan falls behind
- panic starts
- missed hits happen
System 4: Destruction discipline
In tight groups, destruction decides promotions and demotions.
Teach your clan:
- Don’t time fail
- Don’t ignore corner buildings
- Start cleanup early
- Don’t tunnel vision only on the Town Hall if it will cost you 10–15% destruction
A clean 2-star with 85–95% often beats a messy triple attempt that fails into a low percent 2-star.
Common CWL mistakes (and fixes that work immediately)
Mistake: Signing up the wrong war size
Fix: Choose 15v15 if you’re not confident about 30 daily attacks.
Mistake: Letting everyone attack whenever
Fix: Use a daily routine: early hitters first, mid adjustments, late cleanup.
Mistake: No roster rules
Fix: Publish rotation and missed-hit rules before CWL starts.
Mistake: Everyone uses different armies
Fix: Two-army policy by Town Hall bracket.
Mistake: Bonus medals cause drama
Fix: Set a written bonus policy (performance, reliability, growth, or mixed).

FAQ
How long is CWL each month?
CWL runs for a sign-up period followed by a war week where clans fight daily wars across the event.
Is CWL matchmaking based on Town Hall levels?
CWL matchmaking primarily places clans by league tier and group formation rather than classic war weight balancing, which is why planning and roster strength matter so much.
Should we do 15v15 or 30v30?
Choose 15v15 if you have a strong top core and want to push leagues. Choose 30v30 if you have wide activity and want more participation—only if you can prevent missed attacks.
What’s the best way to avoid demotion?
Prevent missed hits, prioritize safe stars over risky triples when needed, and protect destruction percentage for tie-breakers.
How do we assign attacks without arguments?
Use one consistent system: mirror + flex, leader assignments, or first-claim with a time limit. Consistency beats perfection.
