Clan War Leagues (CWL) in Clash of Clans provide clans with an exciting opportunity to compete against others in a series of intense wars. However, many players encounter a frustrating issue known as ‘CWL mismatches’ during these battles.
What is a War Mismatch?
A mismatch happens when clans with a mix of Townhall levels find themselves competing in higher leagues. This can mean facing bases that are much more advanced than theirs, giving the opponent an unfair advantage.
Why do CWL Mismatches Occur?
CWL mismatches in Clash of Clans can occur due to the matchmaking system by Supercell, which is based on the league your clan is in rather than the individual war weights of the bases. This means that a clan with a range of base levels could be matched against a clan with more uniformly high-level bases, leading to mismatches. Additionally, the system does not account for the skill level of the players, only the progression of their bases. This can result in situations where less experienced players with high-level bases are matched against veteran players with lower-level bases.

How does Clan War Matchmaking Work?
- The matchmaking system in Clash of Clans War operates by assessing the total strength of each clan.
- The strength of a clan is determined by several aspects:
- Offensive Strength: This is calculated based on the troops, army camp capacity, and spells of each clan member.
- Defensive Strength: This is evaluated based on the defense buildings, walls, and traps.
- Hero Strength: The heroes of each clan member contribute to both offensive and defensive strength.
- The matchmaking system does not consider trophies, unlike in Multiplayer mode.
- The system attempts to match clans with similar Town Hall levels.
- The layout and design of a base do not impact its strength. The only way to alter a member’s strength is by upgrading their troops, defenses, spells, etc.
- The matchmaking system also takes into account the Win/Loss record of clans to ensure that the opponents are of comparable strength.
- The level of a clan does not influence the matchmaking process.
- Each player and clan receives a ‘war weight’ based on their defensive and offensive levels. The matchmaking system uses these weights to pair clans with opponents of similar strength.
- When initiating a Clan War search, your clan enters a queue with other clans seeking a match. If a clan remains unmatched for a long time, the broader the range of potential opponents becomes, increasing the likelihood of a mismatch.
Strategies to Prevent Mismatches
- Ensure your clan has a balanced composition of Townhall levels.
- Avoid ‘engineering’ your bases or rushing your bases. Some clans engage in ‘engineering’, where they strategically upgrade their bases to gain an advantage in wars. If the matchmaking system categorizes a clan as an engineering clan, it may lead to mismatches.
- Encourage active participation from all clan members.
- Strategically upgrade your bases to ensure they are well-prepared for wars. For example, if I am a new Townhall 13 player, I should first upgrade to TH 12.5 before progressing to TH 13 to maximize defenses.

Conclusion
While CWL mismatches can be discouraging, understanding their causes and implementing effective strategies can make a significant difference. Success in Clash of Clans isn’t just about base strength; it’s about smart tactics and adaptability. By mastering these elements, players can navigate mismatches more effectively and lead their clans to victory. Players who have both a main clan and a feeder clan can start CWL 15v15 with higher league players up to Town Hall 14 in the main clan. In the feeder clan, they can start CWL 30v30 with Town Hall 13 and below players. This approach has yielded better results for us compared to previous strategies.
