What is the Rarest Blook? The Statistical Reality of Drop Rates
Chasing the Mysticals? We break down the exact mathematical odds of pulling Blooket's rarest characters, and why your luck feels so bad.

Editorial posts now link back into the calculator, guide hub, and pack tables so each article supports the wider Blooket topic cluster.
You have spent 15,000 tokens on the Space Pack and still have not seen an Astronaut. It feels like the game is rigged. It is not rigged; human brains are just exceptionally bad at comprehending microscopic probability. Let us look at the undeniable math behind Blooket's rarest drops and rebuild your expectations from scratch.
The Hierarchy of Rarity
Blooket uses a standard gacha-style tier system. Uncommons hover around 15%, Rares drop to 5%, Epics plummet to 1%, and Legendaries sit at a miserable 0.05%. But that is not the bottom. The true rarest pull-able Blooks are the Chromas, and the absolute rarest in existence are the Mysticals.
| Rarity | Drop Rate | Tokens for 90% |
|---|---|---|
| Epic | 1% | ~5,750 |
| Legendary | 0.05% | ~92,000 |
| Chroma | 0.02% | ~287,500 |
| Mystical | 0% from packs | Unobtainable |
PRO TIPThe Trench Truth
A 0.05% drop rate does not mean you are guaranteed the Blook after 2,000 pulls. Because each pull is independent, your cumulative probability of pulling a 0.05% drop after 2,000 attempts is only 63%. Never spend tokens assuming you are due for a win. Use the pack odds calculator to see brutal reality before you blow your balance.
The absolute rarest obtainable Blook fluctuates based on events. Functionally, chasing Chromas like the Rainbow Astronaut is the endgame. Do not stress if you do not have them; mathematically, almost nobody does.

FAQ
What is the rarest Blook you can actually pull?
Chromas at 0.02% drop rate (1 in 5,000 pulls). Mysticals are rarer but cannot be pulled from packs at all.
How many tokens to get a Chroma?
For 90% chance at any specific Chroma, plan on ~287,500 tokens. Use the chase calculator for exact numbers.
Can I get a Mystical Blook from a pack?
No. Mysticals are event-exclusive awards only. No pack contains them, regardless of token spend.
What is the difference between Legendary and Chroma?
Legendaries are 0.05% drop rate (rare but achievable). Chromas are 0.02% (4x rarer) and are visual variants of standard Blooks.
Why does my luck feel so much worse than the math?
Independent probability is unintuitive. A 0.05% rate produces long dry streaks even at expected pull counts. See the deceptive odds post for the full explanation.
