One of the most frequent events! It encourages participation, strategy between the alliance members/leaders and features competitive ranking and rewards!

It is a regular event and occurs every single week! In fact, it stars on a Monday at 00:00 UTC and ends on the following Monday 00:00 UTC! There are 5 phases;
From Monday 00:00 UTC to Wednesday 23:00 UTC, all members in your alliance that are at least Town Center Level 10 may sign up a march for a lane. There are three lanes, each with a capacity of 20 players (for a total of 60). You will notice a score value after registring, this is your combat score, and your order of fighting within a lane depends on that score (largest score fights last). Note: Registration takes a “snapshot” of your current march and all related buffs. Therefore, if you for instance registered when your pets are active, even after the pets expire, the alliance championship registration will “remember” those pet buffs, but they would be lost if you “update” your team later.


You need a minimum of 10 participants in order to be able to enter the matchmaking phase succesfully. The matchmaking phase starts on Wednesday 23:00 UTC and finishes on Thursday 00:00 UTC. In this time, no changes can be made to the registration or lanes, and you will be matched against 5 other alliances in/near your ranking bracket.
There is an 11-hour prep window right before each round, and you have up to 5 rounds of battling. This is the window where your alliance leaders (R5 and R4s) organize your fighters. Except for the very first round (which is totally blind), your leadership can look at how the enemy arranged their three lanes in the previous round, along with their power levels.
Leaders use this intel to position your alliance’s players across the lanes to counter the enemy. Just keep in mind that you are looking at their old data—if the enemy shuffles their players around for the current round, you won’t know until the battle actually starts.

Strategy Advice: To take the win for a round, you have to conquer either two or three lanes. Aiming for a 2-1 victory is your safest and best bet. A good strategy for this tactic would be to focus your firepower on two lanes, fitting your 40 strongest members in them and discarding “1 lane”. You risk earning less points from each round potentially affecting your final ranking if the enemy manages to sweep all 3 flags each round, but it is the best strategy considering a full sweep is rarely possible.
The combat is broken down into 5 separate rounds, with each round lasting exactly 1 hour. The entire event officially wraps up on Saturday at 12:00 UTC.
The Rundown: This is where the actual fighting happens! In each round, your alliance goes head-to-head against one of the other five alliances in your matchmaking bracket.
Important Battle Mechanics:
Totally Hands-Free: Whether you are a brand new R1 or the R5, nobody needs to be online or clicking buttons during this phase. The battles play out automatically based on the setup from the Preparation Phase.
The Top 20 Rule: Only the 20 strongest players assigned to a specific lane will actually step up to fight.
Combat Limit: A single march can only fight a maximum of two times per round. Once your march beats two enemies (or gets defeated), they are done for that hour.
The Battle Phase Rewards: You get rewarded based on how many enemy marches your troops manage to take down.
Defeating 1 enemy march will net you 10x 5-min Research Speed-ups, 20x 10k Bread, 20x 10k Wood, 40x 1k Stone, and 10x 1k Iron.
Defeating 2 enemy marches will reward you with 15x 5-min Research Speed-ups, 30x 10k Bread, 30x 10k Wood, 55x 1k Stone, and 15x 1k Iron!

Completion Phase: From Saturday 12 UTC to Monday 00:00 UTC, your alliance will given a final ranking and set of rewards depending on the results of your rank within the tournament bracket, as well as based on your Tier;
There are 6 tiers with distinct rewards; Stone, Iron, Bronze, Silver, Gold, Diamond
