Pokémon TCG Pocket Luck Calculator
Track your pulls and compare your results to expected odds. This tool gives a practical “luck score” based on the values you enter.
Note: this calculator is unofficial and uses your custom rates. It does not connect to your account or guarantee future pulls.
What this luck calculator pokemon tcg pocket tool does
Pull sessions can feel amazing or brutal, but memory is often biased toward extremes. This luck calculator pokemon tcg pocket page helps you replace “I think I’m unlucky” with real numbers. You enter how many packs you opened, your assumed hit rate, and how many high-rarity cards you got. The tool returns a luck index, percentile, and probability estimate so you can see whether your results are truly unusual.
How to define a “hit” before calculating
Your result is only as good as your definition. Pick one rule and keep it consistent:
- Count only premium rarities (for stricter luck tracking), or
- Count all cards above a baseline rarity (for broader tracking).
If you change definitions every session, your luck score will become noisy and hard to compare over time.
How the calculator measures luck
1) Expected hits
Expected hits = packs opened × hit rate. If you open 100 packs at an 18% hit rate, your expectation is 18 hits.
2) Luck index
Luck index compares actual hits to expected hits:
- 100 = exactly on expectation
- Above 100 = better than expected
- Below 100 = worse than expected
3) Percentile and “at least this lucky” probability
The percentile gives context. A 90th percentile run means your results are better than what most players would get under the same assumptions. The “at least this lucky” probability estimates how often a run this good (or better) can happen randomly.
Sample size matters more than most players think
Small sessions swing wildly. In 10 packs, one extra hit can make you look incredible. In 500 packs, random swings smooth out and your observed rate usually drifts closer to expected odds. If your numbers look extreme, ask: “Did I open enough packs to trust this result?”
Best practices for accurate tracking
- Log every pack, not only “good” sessions.
- Keep one consistent hit definition for all runs.
- Re-check your assumed hit rate when new sets or banners launch.
- Separate total “hits” from “chase cards” so both metrics stay useful.
Interpreting chase card results
Chase cards are usually low-probability outcomes. Even if your overall hits are normal, chase pulls can lag for long stretches. That does not automatically mean rates are wrong—it often means variance is doing what variance does. The chase section helps you compare your pulls to a realistic expected value instead of gut feeling.
FAQ
Can this predict my next pack?
No. It only evaluates past results based on your assumptions.
What if I don’t know the true rates?
Use community estimates or your own long-run data, then update over time. The calculator stays useful as long as you apply a consistent model.
Is being “unlucky” over a short run proof of bad rates?
Usually no. Short runs are noisy. Look at larger samples before making strong conclusions.
