Understand the boundary
The catalog fixes EU membership at September 2026. EU membership, Schengen participation and use of the euro are different criteria. A country’s location in Europe does not by itself qualify it for this question.

Choose an answer for your goal
Malta earns 96 fixed points, Slovenia 94 and Latvia 92. These are practice ratings, not an estimate of each country’s population or how often players choose it. Czech Republic is accepted as an alias for Czechia. In timed practice, compare countries you can spell confidently rather than assuming a longer or smaller-country name is automatically worth more.
Worked examples — reveals answers
- Czech Republic · Accepted
- An explicit alias for Czechia in the frozen membership set.
- Norway · Outside this set
- Being in Europe does not satisfy the EU-membership condition.
- United Kingdom · Outside this set
- Not a member in the September 2026 reference set.
Practice the distinction
Check one member, then a European country absent from the membership list. Next use the 2004-enlargement question: it asks for a smaller set, even though both prompts mention the EU.

Start with the full category, then apply the exact boundary: Membership as of September 2026. Country names and common aliases count. You only need one qualifying answer. A longer name is not automatically rarer.

Question quality signals
These measurements cover completed daily rounds recorded with timing and rejection details. Older rounds without those fields are excluded. At least 20 measured rounds are required per question.
Review thresholds: below 20% accepted, at least 40% timed out, or at least 30% of rounds with an unlisted input. These flags suggest checking the wording and answer coverage; they do not prove an answer is wrong or change points automatically. Abandoned rounds and practice attempts are not included.
How these statistics work
- What is counted
- Source: Krillionio daily submissions. Skips and timeouts count as rounds; practice and Battle are excluded.
- When comparisons appear
- A question needs at least 20 recorded rounds. An answer also needs at least 5 recorded choices within that question.
- What the data can tell you
- These anonymous browser records are not verified unique people or a representative survey. The player rarity index does not change game points or predict the original Krillion game. Raw submissions stay private.
Rule examples & common mix-ups — may reveal answers
- EU membership, founding EEC membership and a specific accession year are different sets. Geographic location in Europe alone is not enough.
These notes explain the question boundary; they are not a ranking of player mistakes.
Why these answers qualify
Each entry belongs to the bounded set defined by the prompt. The named source supports the underlying facts; our editorial scoring is a separate layer.
