What Are Blooks in Blooket?
A Blook is essentially a virtual character or avatar that represents the player in Blooket games. Players can unlock different Blooks by:
-
Opening themed Blook Boxes
-
Participating in limited-time events
-
Winning tournaments or seasonal competitions
Blooks are purely cosmetic, but they add a layer of fun and collectibility to the platform. For younger users especially, collecting rare Blooks is a huge motivation for ongoing play.
How Blooket Categorizes Blook Rarity
Each Blook in the game is assigned a rarity level, which affects how often it appears when opening boxes. Here are the standard rarity tiers in Blooket:
| Rarity | Drop Rate (Approx.) |
|---|---|
| Common | 100% in starter box |
| Uncommon | 13% to 20% |
| Rare | 6% to 10% |
| Epic | 2.5% to 5% |
| Legendary | 0.3% to 1% |
| Chroma | 0.01% to 0.05% (extremely rare) |
| Mystical | One-of-a-kind or limited |
Mysticals are the rarest of all, with most only obtainable during exclusive events or giveaways.
How New Blooks Are Introduced in 2025
Blooket continues to grow, and in 2025, several new Blooks have been introduced through:
-
Holiday events (Valentine’s Day, Halloween, Christmas)
-
New Blook Boxes tied to topics like Mythology, Sci-Fi, and Space
-
Tournaments hosted by Blooket with exclusive prize Blooks
-
Community challenges or school-wide events
Some older Blooks have been retired, making them even rarer today.
Top 5 Rarest Blooks in Blooket (2025)
Let’s break down the top contenders for the rarest Blook this year:
🥇 1. Tim the Alien (Mystical)
Rarity: One-of-a-kind
How to Obtain: 1st place prize in the Blooket Spring Championship 2023
Availability: Not available for unlock since 2023
Why it’s rare: Only one user owns this Blook, making it the rarest Blook in existence. As of 2025, it has not been re-released and remains exclusive.
🥈 2. Phantom King (Chroma/Mystical Hybrid)
Rarity: Mythical Tier, ultra-limited
How to Obtain: Halloween event reward (2022 & 2024 limited release)
Drop Rate: Less than 0.05% (during event only)
Why it’s rare: Limited-time availability combined with extremely low drop rates makes this a near-impossible Blook to obtain today.
🥉 3. Cyan Astronaut (Chroma)
Rarity: Chroma
How to Obtain: Space Box (now retired)
Drop Rate: 0.04%
Why it’s rare: The box it came from is no longer available, and the drop rate was one of the lowest ever in Blooket.
⭐ 4. Mega Bot (Legendary)
Rarity: Legendary
How to Obtain: Factory Box
Drop Rate: 0.3%
Why it’s rare: While not as rare as a Mystical, it remains one of the hardest Legendary Blooks to get. Many players open hundreds of boxes without seeing one.
⭐ 5. Spring Frog (Chroma)
Rarity: Chroma
How to Obtain: Spring 2025 Event
Drop Rate: Unknown (estimated at 0.03%)
Why it’s rare: It was only available for one week during a limited spring-themed challenge in early 2025.
So, What Is the Rarest Blook in Blooket in 2025?
The answer is clear:
✅ Tim the Alien remains the rarest Blook in Blooket as of 2025.
Only one player in the world owns it, and no other users have been given access. Even the second-rarest Blooks have been unlocked by at least a few dozen players.
While Tim the Alien might not be accessible anymore, understanding what makes it rare can help you hunt for the next ultra-exclusive Blook that might appear in future events.
How to Increase Your Chances of Getting Rare Blooks
If you’re aiming for high-rarity Blooks, here are some actionable tips:
💰 1. Earn More Tokens
Tokens are the in-game currency used to open Blook Boxes. Play daily games and complete classroom assignments to earn tokens regularly.
🎁 2. Save Tokens for Limited-Time Boxes
Don’t waste tokens on common boxes when holiday or event boxes are available—they often contain rare Chromas and new Blooks.
🔁 3. Open in Batches
Statistically, your odds don’t improve by opening one box at a time. Save up for 10–50 boxes and open them in one session for better luck perception.
🏆 4. Participate in Events
Join school-wide, seasonal, or community tournaments—many exclusive Blooks are only available through these events.
💬 5. Follow Blooket’s Official Channels
Stay informed via Blooket’s Twitter, Discord server, and the official blog for announcements about new Blooks or boxes.
Why Are Rare Blooks So Desirable?
Though they don’t affect gameplay, rare Blooks provide:
-
Status and recognition in classroom or public lobbies
-
Motivation to keep playing and collecting
-
A fun way to express individuality
Some teachers even use Blook unlocks as rewards or incentives, making the desire to obtain rare ones even stronger.
Is It Possible to Trade or Gift Blooks?
As of now (2025), Blooket does not allow trading or gifting of Blooks between users. Every Blook must be earned individually, maintaining the integrity and challenge of the collection system.
For passionate Blooket players and collectors, the pursuit of the rarest Blooks adds a thrilling dimension to an already fun educational experience. In 2025, Tim the Alien continues to hold the crown as the rarest Blook ever released—owned by only one player, with no signs of a re-release.
But new events and limited-time boxes are always on the horizon. With patience, strategy, and a little luck, you could be the next player to unlock a Blook that becomes the talk of the community.
So keep playing, keep collecting, and most of all—have fun chasing your next rare Blook!
