Methodology

What the calculator models

The real-time calculator path uses the exact at-least-one-success formula: P(at least 1) = 1 - (1 - p)^n. Here, p is the single-open success rate for the selected pack target and n is the number of expected opens your token budget can fund.

That means the site is not faking odds with vague rarity language. It is converting known pack rates into a budget-specific probability.

How duplicate refunds are handled

Duplicate refunds are modeled with a precomputed effective-cost constant for each pack instead of recursively simulating every possible sell-back loop in the live UI path. This keeps the calculator fast and stable while still reflecting the long-run effect of selling duplicates.

When you want a heavier simulation pass, the optional worker-based flow runs separately so the main interface stays responsive.

What our sources are

We use official Blooket help articles for current product behavior such as the Market flow, Blook Score behavior, and selling interface. We use community references for pack tables and broader collector taxonomy where official public documentation is limited.

If a topic cannot be responsibly tied back to the pack data we index, we say so. That is why pages like Mystical Blooks explain taxonomy without pretending there is a normal pack probability behind it.

Update policy

We do not quietly invent fresh data. Pack tables, support pages, and topical guides should move together. When a major change lands, we update the relevant content, refresh machine-readable surfaces like the sitemap and feeds, and log the change in the updates page.
