The Ultimate Guide to Blooket Chroma Blooks (2025)
What are Chroma Blooks?
Chroma Blooks are the rarest and most coveted Blooks in the game. Distinguished by their unique color variations of standard Blooks, they are the ultimate status symbol for any Blooket collector.
Why are they so hard to get?
The rarity of Chromas comes down to pure mathematics. With drop rates typically hovering between 0.02% and 0.05%, you are looking at a 1 in 2,000 to 1 in 5,000 chance per pack opening.
Best Packs for Hunting Chromas
Not all packs are created equal when it comes to hunting Chromas. Here is a breakdown of the best packs to spend your tokens on:
| Pack Name | Cost | Chroma Chance | Notable Chromas |
|---|---|---|---|
| Space Pack | 25 | 0.05% | Red Astronaut, Blue Astronaut, etc. |
| Aquatic Pack | 25 | 0.02% - 0.05% | Lovely Frog, etc. |
| Wonderland Pack | 20 | ~0.03% | Cheshire Cat (Chroma) |
Strategy: The Space Pack
The Space Pack is often considered the best "starter" pack for Chroma hunters because it has multiple color variants of the Astronaut, effectively increasing your overall odds of pulling any Chroma compared to packs with only one single Chroma target.
