This a weekly competition running on weekdays among players, where you can perform maximum 5 Raids with specific restrictions, which uses a special energy.
1. Overall Process for the Tournament
Raid Tournaments have 3 phases:
- Preparation Phase that lasts for 24 hours. During the preparation phase you join the up coming Tournament and prepare your defense team. You can only use defense teams that match the event rules.
- Battle Phase that lasts for five days. The Battle Phase is divided to Five Battle Days where you have five attacks available for each Battle Day. You can only use attack teams that match the event rules.
- Reward Phase that lasts two days. Your final score will determine your reward tier. You get rewards only from the highest reward tier that you belong to.
2. How Attacking Works
Other than restrictions on heroes/troops and Special Rules, the Raids themselves in Weekly Raid Tournaments work the same way as regular Raids.
Each day, you'll be able to attack up to 5 teams.
The flags used for Raid Tournaments are separate from regular Raid flags.
NOTE: Kills in Raid Tournaments count toward your Wanted: Heroes Raid Chest, so Raid Tournaments also effectively give you extra flags to potentially help fill your chest.
One notable difference to Regular Raids — you can’t reroll.
For the whole of the Tournament, you have 4 "Lives." Each time you lose a Raid, you lose one life.
The lives do not reset across days of the Tournament. Once you'd lost 4 times at any point during the Tournament, you are out.
If you choose, you can pay some gems to reset your lives after 4 losses — but your score and ranking would still be lowered because of the losses. Paying to reset your lives does NOT give you an advantage from the Raids you've already fought. It simply allows you to continue using your normal 5 flags per day and not be "out" of the Tournament.
There is no way to buy additional flags. So everyone ultimately had the same number of maximum flags to use for attacks during the Tournament. The only thing gems allow you to do is continue playing if you've used up all of your lives.
3. Matchmaking for Attacks
As of the Third Raid Tournament, initial matchmaking was based on your Top 5 strongest heroes that qualified for the Tournament's rarity and elemental restrictions.
This was slightly amended as of the Fourth Raid Tournament:
> The difficulty of the opponents reduced slightly in the beginning of tournaments.
4. Matchmaking for Defense
As of the Sixth Raid Tournament, matchmaking for Defense teams was changed again:
- Further improvements to the distribution of attacks, especially for the top players.
- Keep in mind that if you're in the top, your defense team will receive more attacks. This is due to the fact that there is a small number of top defense teams that are good matches for a large number of top attackers. We try to prioritize choosing a good opponent over choosing a too easy or too difficult opponent that hasn't been attacked as much. We have also implemented a limit on how attacks count towards your Defense Grade. After the first five attacks of the day, only one attack per hour counts towards the grade.
- Changes to the starting difficulty of opponents your defense team faces.
- It is no longer based on the defense team you pick, but your best heroes that match the tournament requirements. We've brought this rule back because we want to encourage players to choose the best defense team they can, and thus provide a better challenge to their opponents. Due to the way the Team Power is calculated it was possible, for example, to pick a defense team of two fully leveled, fully ascended heroes that were on paper equal in Team Power with a full team of lower rarity heroes, but in practice that full team would be defeated in most cases.
5. Scoring
Raid Tournaments are scored based on four factors:
- Enemies killed: The amount of enemies killed during your attack.
- Winning: Victorious attack will award extra points.
- Difficulty Bonus: Winning the attack will award points based on comparing the performance of the opponent’s defense team with the performance of your attacks.
- Defense Team Grade: Your defense team will receive points in the end of each Battle Day based on their performance.
6. Defense Team Grade
The grades are assigned based on a percentage of wins by your Defense Team:
The Defense Grade is determined based on the win percentage of your Defense Team. At the end of each Battle Day, you receive points based on your grade.
| Percent Won | Grade | Points |
| 60% | A | 900 |
| 50% | B | 650 |
| 40% | C | 500 |
| 30% | D | 400 |
| 0% | E | 200 |
