Blooket Chase Calculator

Every chase shares the same math — 1 − (1 − p)ⁿ for cumulative chance, ln(0.5) / ln(1 − p) for the 50% threshold. Splitting that across 30+ template pages would be padding, not utility. The dropdown lets you compare chases side-by-side without losing your inputs.

Mega Bot is the rarest pack-pullable Legendary at 0.03% — that's about 2,300 packs to a 50% chance. The rarest Chromas tie at 0.02% (Rainbow Panda, Ice Crab, retired Tropical Globe). Tim the Alien is technically rarer (Mystical contest prize) but isn't pullable from any pack.

Use ln(0.5) / ln(1 − p), where p is the per-pack drop rate. For a 0.02% Chroma it's ~3,465 packs; for a 0.3% Legendary it's ~231 packs; for a 0.05% rotating Chroma it's ~1,386 packs. The picker above does this automatically — pick the chase, the 50/90 numbers refresh.

We still keep them in the picker because the search demand is real. The math is correct for the historical drop rate, but you can't actually open the pack right now — it'd take a Blooket rerun. The chase row tags retired packs explicitly so you know.

No. Drop rates are per-pack and identical regardless of mode. The only thing that changes between modes is how fast you accumulate tokens — and that's covered by the token-grind calculator, not chase math.

Because nobody chases those — they fall in the first 100 packs. We list every Legendary, every Chroma, plus the few Epics players actually plan budgets around (Pizza in Breakfast Pack, for example). If you want every pull, including Commons, use the pack-specific calculators instead.
