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.
You have spent 15,000 tokens on the Space Box and still haven't seen an Astronaut. It feels like the game is rigged. It isn't rigged; human brains are just exceptionally bad at comprehending microscopic probability. Let's look at the undeniable math behind Blooket's rarest drops.
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 isn't the bottom. The true rarest Blooks are the Chromas and Mysticals.
Chroma Blooks
0.02% Drop Rate
Found in standard boxes. You have a 1 in 5,000 chance of pulling one. Yes, it will take months.
Mystical Blooks
Award Only
Cannot be pulled from boxes. Given out to winners of specific global Blooket events.
PRO TIPThe Trench Truth
A 0.05% drop rate doesn't mean you are guaranteed to get the Blook after 2,000 pulls. Because each pull is an independent event, your cumulative probability of pulling a 0.05% drop after 2,000 attempts is only about 63%. Never spend tokens assuming you are "due" for a win. Use our pack simulator to see the brutal reality before you blow your balance.
The absolute rarest obtainable Blook in the game fluctuates based on events, but functionally, chasing Chromas like the Rainbow Astronaut is the endgame. Don't stress if you don't have them; mathematically, almost nobody does.
