1. Unofficial fan project
blooketcalculator.us is a fan-made site built by Blook Enthusiast, based in Austin, Texas. It is not affiliated with, endorsed by, or operated by Blooket, Play Blooket, LLC, or any of their subsidiaries or partners. All Blooket-related marks, pack artwork, and Blook names remain the property of their respective owners.
2. Drop rates come from community sources
Blooket does not publish an official drop-rate API. The numbers used by every calculator on this site are sourced from the Blooket Wiki on Fandom and corroborated by community audit threads. We verify large-scale rate changes manually when Blooket ships a patch, but small deviations between the numbers on this site and the current in-game rates are possible.
If you notice a mismatch, please contact us or email hello@blooketcalculator.us. Corrections are applied in the next monthly refresh.
3. Calculators model probability, not guarantees
Pack opening in Blooket is an independent-trial probability system. Each pack is a fresh dice roll; prior pulls do not influence future outcomes. The calculators on this site compute cumulative probability: the chance that at least one of your planned openings produces the target. They do not guarantee you will pull anything. For a deeper walk-through of this distinction, see How Drop Rates Work and The 50/90 Rule.
4. Not gambling, not financial advice
Blooket tokens are an in-game currency with no real-world monetary value. Pack openings in Blooket are not gambling and this site does not model any form of wagering. Nothing on blooketcalculator.us is financial, investment, educational, or psychological advice. If a child in your care is developing compulsive-seeming patterns around in-game pulls, we recommend stepping back from the platform and talking to a qualified professional, not using a calculator.
5. The site can be wrong
We're a small fan project. Specific kinds of errors we have seen before, which you should watch for:
- Rate lag. A Blooket patch changes a pack's rates and our numbers haven't caught up yet.
- Missing Blooks. A newly-released chase isn't in the catalog. The calculator will still run, but the new Blook won't appear in its list.
- Rounding differences. Our math rounds at several points; the last decimal place of an output may differ from an in-game display.
- Typos. Guides are written by one person. Please flag any you see.
6. Educational use
Teachers are welcome to link to this site from classroom materials to help students understand probability. The calculators, guides, and rarity tables double as approachable examples of binomial probability and geometric distributions in practice. If you adapt this material for a lesson, a link back is appreciated but not required.
7. Accessibility
We try to follow standard web-accessibility practices: semantic HTML, sufficient color contrast, keyboard-navigable interfaces, and plain-language writing. If you encounter an accessibility issue while using the site, let us know or email hello@blooketcalculator.us and we'll fix it as quickly as we can.
8. Summary
This site is a free, volunteer-built tool to help Blooket players think clearly about probability before spending tokens. It is not official, not perfect, and not a substitute for your own judgement. Use it as one input among several, and have fun.
