About Luck Tester
How your luck is measured
One tap draws ten cards with the browser's secure randomness, each independently landing on 1★ (50%), 2★ (35%), 3★ (12%) or 4★ (3%) — more stars, rarer card. Star tiers convert to a weighted score, and the tool compares your total against the exactly computed distribution of every possible ten-pull. The result is a percentile — how many theoretical runs yours beats — and a matching title.
When to test your luck
Warm up before a gacha ten-pull, look for a good omen before buying a lottery ticket, check your form before a card game, or settle a friendly argument about who is luckier today — with a number instead of a feeling. Each round takes about ten seconds and costs nothing.
What this tool does not claim
The percentile describes this run only — every round is independent, and a legendary streak now says nothing about your next pull. The odds table is this tool's own fixed design and does not match any specific game, lottery or real-world probability. Treat the title as a fun snapshot, never as advice for spending money or making decisions.
FAQ
Common questions and answers about this topic.
How do I use Luck Tester?
Tap “Test my luck” and ten cards flip open one by one. When the last card lands you get your score's percentile against all theoretical ten-pulls, plus a luck title. Tap “Test another round” to draw again — no input, no sign-in.
How is the percentile calculated?
Each star tier carries a weighted score, so a ten-pull sums to one total. The tool computes the exact probability of every possible total (not a simulation), then reports the share of theoretical runs scoring below yours, counting ties as half. That is why the number is honest: it comes from the full distribution, not from other visitors' results.
Does it predict my future luck?
No. Every round is an independent random draw, and the percentile only describes the cards you just flipped. It is a fun, honest statistic about this run — not fortune-telling, and not advice for gacha spending, lottery tickets or any decision.
What are the odds? Are they fair?
Every card independently lands on 1★ 50%, 2★ 35%, 3★ 12% or 4★ 3% — fixed, public, and identical for everyone. Draws use the browser's cryptographically secure randomness, and automated tests verify the long-run frequencies stay within tolerance of the table.
Is anything saved or uploaded?
No. Results live only on the current page — there is no account, no history and no upload. Refreshing the page clears everything; sharing a result card is always your explicit choice.
What titles can I get?
Five tiers by percentile: Fully Cursed (bottom 5%), Slightly Cursed (5–25%), Perfectly Average (25–75%), On a Lucky Streak (75–95%) and Gacha Blessed (top 5%). Most runs land in the middle — that is exactly what the math says should happen.
