Data Inputs (What the Calculator Uses)
For each pack, the calculator uses a set of drop-rate inputs:
- Pack cost (tokens per opening)
- Rarity drop rates (Uncommon, Rare, Epic, Legendary, Chroma)
- Pack-specific chase blooks (the named Legendary or Chroma you can pull)
These rates are treated as probabilities per pack opening. BlooketIQ's results are only as accurate as the underlying rates, and Blooket can change odds at any time.
Pack Openings From Tokens (Base Packs)
The calculator converts your tokens into base pack openings using:
Cumulative Chance for a Specific Legendary or Chroma
Most players don't want "one-pack odds." They want: "What is my chance of pulling at least one chase blook after opening N packs?"
BlooketIQ calculates "at least one" chance using cumulative probability:
Notes on interpretation
- Cumulative chance increases as N increases
- It still does not guarantee a pull
- Very low p values (typical for Chromas) increase slowly — which is why long grinds are common
Expected Rarity Drops (Estimated Counts)
BlooketIQ also shows expected drops by rarity tier. This is an expected value estimate:
If expected Legendaries = 1.3, it means "about 1 on average over time" — not "you will get exactly 1." This is why results can differ from real openings even when the math is correct — randomness creates variation.
Strategy Mode (Sell Duplicates) — Expected Value Model
Strategy Mode estimates additional pack openings by reinvesting token returns from selling duplicates of lower tiers.
What is included
- Uncommon resell value (assumed token return)
- Rare resell value (assumed token return)
- Epic resell value (assumed token return)
What is excluded
- Legendary and Chroma are excluded — the model assumes collectors keep them
Expected resell value per pack
Strategy Mode calculates an expected token return per pack using weighted probability:
Effective cost and total packs
It then estimates an effective cost and converts your token amount into total estimated openings:
Safety cap
To avoid unrealistic outcomes, the calculator uses a safety floor so effective cost cannot drop below a fixed minimum percentage of the pack cost. This prevents Strategy Mode from producing extreme "infinite pack" behaviour when assumptions are too favourable.
Time-to-Earn Estimate (Token Grind Time)
BlooketIQ can estimate how long it might take to earn the token amount entered. The tool uses a simple average-rate assumption:
Limitations (What the Calculator Can't Guarantee)
BlooketIQ is mathematically consistent, but outcomes are still random and data can change. Key limitations:
- Randomness — probability is not a promise
- Drop-rate changes — if Blooket updates odds, results may become outdated
- Community-sourced rates — some values are based on observed data and may be incomplete
- Strategy behaviour — resell choices vary by player, and real drops vary
Use the Calculator With the Right Expectation
BlooketIQ is built to answer planning questions — how many packs, what cumulative chance, what rarity totals on average, how Strategy Mode changes your estimated openings.
