Fixed Scores and Player Rarity
Separate a correct answer, its fixed knowledge points and its observed choice frequency before deciding what to practice.
Accepted answers, fixed points and frequency
An answer must first meet the selected question’s rule. Each accepted answer then earns a fixed editorial knowledge score. Player Rarity Index records how often that answer was submitted in daily rounds; it does not change the score.
For our rocky-planet question, Mercury earns 69 points and Venus 56. That is a scoring decision in this edition. It does not establish that 69% of players miss Mercury or that it is 13 percentage points rarer than Venus. A factual source establishes membership in the answer set, not the editorial score.
Calculate the Player Rarity Index
Choice share = recorded choices of an answer ÷ all recorded rounds for that exact prompt. Player Rarity Index = 100 × (1 − choice share). A higher index means a smaller observed share. The index does not change your score.
Worked example, not live data: suppose 10 of 50 rounds choose Mercury, 30 choose other answers and 10 end without an accepted answer. Mercury’s share is 20% and its index is 80. Dividing by only the 40 accepted rounds would instead produce 25%; that is a different denominator from the one used on this site.
Read the sample before the ranking
Our comparisons use the previous 30 completed UTC days and require at least 20 rounds for a question and five choices for an answer. Skips and timeouts stay in the denominator. Aliases are grouped under their canonical answer; practice and Battle are excluded. Zero observations do not establish rarity, so unchosen answers are not ranked.
These thresholds are publication rules, not statistical guarantees. Records use anonymous browser identifiers, not verified people. Repeat visitors, multiple devices, automation and which days a prompt appeared can affect the sample. This is not a representative survey or a prediction for the original Krillion audience.
Use the right measure for your next game
In a solo dive, a high-scoring accepted answer keeps its points even if many players choose it. In Battle, shared canonical answers cancel, so practice several eligible alternatives. Population counts from daily play cannot tell you what your particular opponents will choose.
Open Player Insights for the recorded period and sample sizes. Compare a frequently chosen high scorer with an uncommon lower scorer, then practice both. Treat the comparison as a recall exercise rather than a guaranteed winning tactic.
