Build a subdivision flag round

Choose a country or region set, then identify each subdivision flag from the curated public-media practice bank.

Question counts follow the number of curated flags available in the selected set.
This bank practices visual recognition, not legal status or official flag protocol.
Choose a short review or the largest legal round available for this set.
Keep this seed to replay the same flag challenge later.

Below the national level, flags can represent states, provinces, territories, regions, departments, cantons, counties, emirates, prefectures, and other local units. Those labels are not interchangeable. Each country organizes its territory differently, and the legal or customary standing of a flag can vary just as much as its design.

Subdivision flags often reuse national colors, local coats of arms, seals, geometric patterns, or historic emblems. Similar designs within one country make recognition a fine-detail task. The position of a shield, the number of stars, a border color, or one central symbol may separate otherwise close choices.

FactorEffect on recognition
Administrative vocabularyA state, province, county, canton, or region reflects the selected country's own structure.
Design familiesSeveral subdivisions may share a template and differ only in a seal, emblem, or small color detail.
Source coveragePublic media collections can be incomplete, unevenly licensed, or slower to reflect a redesign.
Official statusA widely used public image is not by itself proof of legal adoption or protocol rules.

ISO 3166-2 supplies internationally recognized codes for principal subdivisions, but it does not serve as a complete flag registry. A code can help identify a subdivision consistently while the flag image, name, adoption date, and official use still require appropriate national or local sources.

Focused country sets keep the distractors meaningful. Comparing Malaysian state and federal-territory flags, Japanese prefecture flags, or Swiss canton flags asks for a different visual vocabulary in each case. A round from one set does not measure recognition across the other 47 available sets.

The bank is a curated visual practice collection, not a statement about sovereignty, constitutional rank, current administrative boundaries, or flag protocol. Names, units, and designs can change; verify consequential claims with the responsible authority.

How to Use This Tool:

Choose one country or region set so the corrections teach a coherent family of designs.

  1. Select Country or region set. The available Question count changes with the number of curated flags in that set.
  2. Choose a short review or the largest offered round. Questions are selected without replacement, so a subdivision appears at most once in the attempt.
  3. Keep Recognition mode selected. Retain the Replay seed when you want the same flags and answer order, or use a new seed for a different sample.
  4. Study the image, choose one of four subdivision names, and read the immediate explanation. If the image cannot load, change setup or start a new session; the blocked item is not scored.
  5. Use the completed review to retry misses, repeat the same seed, or return to setup for another subdivision family.

Interpreting Results:

The score describes one sampled round from one curated set. It does not establish complete coverage of that country's subdivisions, legal knowledge, or long-term recall.

  • Learning review identifies each missed flag and the source-attributed subdivision name to study.
  • Set performance compares correct and missed answers for the selected set; it is a round summary, not a comparison among all countries.
  • Answer ledger provides the exact prompt, selected answer, correct answer, outcome, explanation, and source record for every scored item.

Technical Details:

The bank version dated 2026-07-23 contains 802 image-backed items across 48 country or region sets. Each item binds a stable subdivision answer to public flag media and a source record. The collection is explicitly curated, so the available item count is evidence about this bank rather than an official count of subdivisions.

Lookup Core

Set sizes range from four items to 97, and legal round sizes are declared separately for each set. The examples below show why one universal question-count menu would be misleading.

Rule Core

StageRule
SessionThe selected set, recognition mode, legal count, and seed determine the question identities and option order.
SelectionQuestions are drawn without replacement and each prompt receives four valid answer choices.
ScoringThe recorded stable answer identity must match the keyed subdivision identity for one point.
MediaA prompt-image failure blocks scoring for that item; a later review-image failure leaves the recorded score unchanged.
ReplaySame-seed replay reproduces the challenge, while missed replay creates a new attempt limited to missed identities.

Formula Core

A correct answer earns one point and an incorrect answer earns zero. There is no partial or negative score.

Apercent=NcorrectNanswered×100

The percentage is rounded for display. Review cards, the performance chart, and the ledger all use the same scored answer rows.

Source, Accuracy, and Privacy Notes:

Prompt images load from Wikimedia Commons file pages, and individual files retain their own licenses and attribution requirements. Public availability does not establish that every image is current, official, or complete.

  • The 48 sets vary widely in coverage. A displayed set size is the curated item count, not a legal census of that subdivision type.
  • ISO 3166-2 helps identify principal subdivisions but does not validate each flag's design or status.
  • Loading a flag contacts the external media host. Quiz state may also be encoded in a restoration link, so do not treat the page URL as private.
  • For classroom comparison, hold the set, count, and seed constant. For current official use, check the relevant national or subdivision authority.
