Supercell is running another limited-time event in Clash of Clans, and this one rewards consistency instead of raw skill. The new Cosmic Streak Event begins on October 16 at 8:00 a.m. UTC and finishes on October 31 at 8:00 a.m. UTC. Roughly one attack a day across the two-week window is enough to collect the full reward line.
Returning and newer players get the most from the format, since the whole point is building a habit of logging back in. Here is everything confirmed about the daily streak rules, the exclusive rewards, and the community goal bonuses that unlock for the whole player base.
Quick Answer
The new Cosmic Streak Event in Clash of Clans runs from October 16 to October 31 at 8:00 a.m. UTC. Complete one attack per day in either village to build a streak and earn exclusive rewards, including chests, a clan castle cake, and an event decoration. Community goals unlock a Lava Loon event, a two times star bonus, and an upgraded decoration.
How the Cosmic Streak Event Works
Once the event goes live, a separate event button appears on the main screen and takes you straight into the Cosmic Streak menu. A small red notification pops up on that button each day at 8:00 a.m. UTC, reminding you that a daily attack is waiting.
Building the streak is simple. One attack per day counts, and it can be in your home village or your builder base. No win is required, so starting an attack and quitting would technically register, though a quick farming attack makes more sense since you are online anyway.
Your current streak shows on the left side of the event screen, and the reveal video shows the display getting more dramatic as you climb toward seven days. Scroll across the same screen to preview every reward on offer.
Daily Rewards and the Event Decoration
Rewards unlock based on your best streak, not your current one. Three straight days of attacks followed by a miss and a restart still leaves your first three rewards claimable. You simply have to rebuild the streak before anything further opens up.
| Day | Reward | Notes |
|---|---|---|
| 1 | Chest | Claim it right away or hold it in the event menu |
| 2 | Builder bite | One attack that day is all it takes |
| 3 | Mighty muscle | Paired with the first community goal |
| 4 | Chest | Streak still intact |
| 5 | Two builder bites | Paired with the star bonus community goal |
| 6 | Clan castle cake | Strongest standard reward in the line |
| 7 | Event decoration | Exclusive to this event, plus the final community goal |
The day seven event decoration is the headline personal prize and can be placed in your home village once claimed. Every reward on this list must be claimed manually. Nothing auto claims, and the claim window closes on November 1 at 8:00 a.m. UTC.
Community Goals Explained
Three community goals sit alongside the personal rewards, and the targets scale down as the streaks get longer. Casual play across millions of accounts makes high streaks harder to hit, so the later goals ask for fewer players.
Lava Loon event on day three
If 20 million players complete a three-day streak before October 21 at 8:00 a.m. UTC, a mass troop injection event follows. That means 50 Lava Loons donated in one hit, available from October 21 through October 22, a 24-hour window. Hitting the target early does not move the date, so the injection still lands on the 21st and 22nd.
Two times star bonus on day five
The second goal drops to 15 million players reaching a five-day streak before October 25 at 8:00 a.m. UTC. Clearing it turns on a two times star bonus that runs from October 25 at 8:00 a.m. UTC until November 1. Star bonuses stack for two days, so holding one from the 24th lets you squeeze an extra bonus day out of the window.
Upgraded decoration on day seven
The final goal needs 10 million players to reach a seven-day streak. Clearing it upgrades the event decoration to a version with a purple skull and flames. This one is personal: you have to hit the seven-day streak yourself to claim the upgraded look, even though the rest of the server carries you to the target.
Key Things to Remember
- One attack per day keeps the streak alive, home village or builder base.
- Rewards follow your best streak, so a broken streak never erases earned loot.
- Nothing auto claims, so open the event menu before November 1 at 8:00 a.m. UTC.
- The Lava Loon event and star bonus go to everyone once the goals are met.
- The upgraded decoration requires your own seven-day streak, no exceptions.
Active players who clear the streak early should still check back before the event closes. The upgraded decoration only appears once the community goal is met, and a quick visit to the event menu is all it takes to grab it.

FAQ
What is the new Cosmic Streak Event in Clash of Clans?
It is a limited-time event running October 16 to October 31 at 8:00 a.m. UTC. Players complete one attack per day to build a streak and unlock rewards, with community goals adding server-wide bonuses like the Lava Loon event and a two times star bonus.
Does my attack need to be a win to count?
No outcome requirement has been confirmed, so an attack you start and abandon would likely register. That said, a single farming attack takes barely longer and gives you loot instead of a zero-percent result.
What happens if I miss a day?
Your streak breaks and resets, but rewards already earned stay claimable because they track your best streak. You then need to rebuild past that point before later rewards unlock again.
When do I have to claim my rewards?
Streak contributions stop on October 31 at 8:00 a.m. UTC, and unclaimed rewards remain available until November 1 at 8:00 a.m. UTC. Nothing claims automatically, so a missed visit means a missed reward.
How do the community goals work?
They set player targets for three-day, five-day, and seven-day streaks. Hitting the first two unlocks a Lava Loon event and a two times star bonus for everyone, while the seven-day goal upgrades the event decoration for players who personally reached seven days.
Can I get the upgraded event decoration without a seven-day streak?
No. The community has to reach 10 million players on a seven-day streak, and you also need your own seven-day streak to claim the upgraded version with the purple skull and flames.
Final Thoughts
Chasing the new Cosmic Streak Event costs one attack a day, which is a fair trade for a chest line, a clan castle cake, and an exclusive decoration. The community goals add a nice shared layer, and stacking a star bonus before October 25 is a small trick worth using. Keep an eye on the event menu and claim everything before November 1.
