Who's behind this
The site is built and maintained by Blook Enthusiast, a one-person fan project based in Austin, Texas. No investors, no paid influencer deals. The only goal is to keep the pack-opening math honest and the page loads fast.
Why it exists
Pack-opening math is not intuitive. "0.02% drop rate" does not mean "one in five thousand packs and you're guaranteed." It means your chance of missing it on any single pack is 99.98%, and that the cumulative chance curve bends in surprising places. Most Blooket players end up spending more tokens than they budgeted because the intuition is off by a factor of two or three. This site exists to fix that. Plug in real numbers, see real probabilities, decide before you spend.
Where the data comes from
Drop rates on this site are sourced from the Blooket Wiki on Fandom and active community audit threads. Rates are refreshed monthly and after any Blooket update that touches pack economy. If you spot a mismatch with in-game rates, send us a note or email hello@blooketcalculator.us. Corrections ship the same week.
What we don't do
- We don't claim affiliation with Blooket or Play Blooket, LLC.
- We don't collect personal information or require sign-ups.
- We don't simulate real-money gambling. Blooket tokens have no cash value.
- We don't store your calculator inputs. Every session is fresh.
How it's built
Modern React with Next.js on the server side, TypeScript throughout, Tailwind for styling. Every route renders on the server, so there's no client-only page, which keeps the site fast, accessible, and friendly to search engines. The math lives in a small, testable library; the calculators are thin UIs on top.
What's on the site
Three kinds of things:
- Calculators. Pack odds, token conversion, chase probability, ROI, pack threshold. Every common question gets a dedicated tool. See the full calculator index.
- Guides. Plain-English explanations of the math, budgeting strategies, and common mistakes. Start with the 50/90 rule or how drop rates work.
- Reference. Pack and Blook catalogs with all the numbers in one place: Blook Value Guide, Blooks hub, Packs hub.
