Who is 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. A 0.02% drop rate does not mean “one in five thousand packs and you are guaranteed.” It means your chance of missing on any single pack is 99.98%, and the cumulative probability curve bends in surprising places. Most players end up spending more tokens than they budgeted because the intuition is off by a factor of two or three.
There is also a lot of misinformation circulating about Blooket mechanics, wrong Daily Wheel expected values (~35 tokens instead of the correct ~47), false claims that Blooket Plus gives a token multiplier or raises the daily cap, and mythical pity timers that do not exist. This site exists to replace all of that with verified numbers. Plug in real numbers, see real probabilities, decide before you spend.
Where the data comes from
Drop rates are sourced from the Blooket Wiki on Fandom and corroborated against community audit threads and in-game testing. Rates are refreshed after any Blooket update that touches the pack economy. The full rate data lives in lib/data/packs.ts and lib/data/chases.tsin the site's codebase.
If you spot a mismatch between what is shown here and what you see in-game, send us a note or email hello@blooketcalc.us. Verified corrections ship the same week.
What we do not do
- We do not claim affiliation with Blooket or Play Blooket, LLC.
- We do not collect personal information or require sign-ups.
- We do not simulate real-money gambling. Blooket tokens have no cash value.
- We do not store your calculator inputs. Every session starts fresh.
- We do not publish unverified mechanical claims. If a number is not backed by the wiki or in-game testing, it does not go on the site.
How it is built
Modern React with Next.js on the server side, TypeScript throughout, Tailwind for styling. Every route renders server-side, so there is no client-only page, this keeps the site fast, accessible, and search-friendly. The math lives in a small, tested library; the calculators are thin UIs on top.
Analytics are handled by Google Analytics (GA4, measurement ID G-95D3WQQE4B), loaded after the initial page render. No personal data is collected by the site itself; see the privacy policy for details.
What is on the site
Three kinds of things:
- Calculators. Pack odds, token conversion, chase probability, ROI, Daily Wheel EV, and resell math. Every common question gets a dedicated tool. The chance calculator is the flagship, probability, thresholds, and rate framings in one place.
- 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.
