Flag Rush

How to Play

• Choose the flag that matches the displayed country name from 4 choices.
• Cross layout supports taps, clicks, arrow keys, and swipes. The single-row layout supports taps, clicks, and Q/W/E/R. The 2×2 layout supports taps, clicks, and number keys: 4/5 on top and 1/2 below. Change and save your layout on the start or pause screen.
• You automatically earn and activate an item every 1,000 SCORE.
• The time limit starts at 30 seconds. The game ends when your remaining time reaches 0.

Time and Combos

• A correct answer adds 1 second to your remaining time.
• A mistake removes 2 seconds and resets your combo to 0.
• Every 5 consecutive correct answers earns a combo bonus: COMBO 5 gives +1 second/+10 points, 10 gives +2 seconds/+20 points, 15 gives +3 seconds/+30 points, and every multiple of 5 from 20 onward gives +4 seconds/+40 points.

Hints

• After 2 seconds, a blurred version of the correct flag appears as a hint.
• The hint gradually becomes clearer and is fully visible 8 seconds after the question begins.

Score

Correct answers within 1 second earn 100 points. Each additional 0.1 second reduces the base score by 1 point, down to a minimum of 10. Mistakes do not deduct points. The table shows examples at each answer time.

Items

• You earn 1 random item every 1,000 SCORE.
• The item card appears in the slot for 1.5 seconds, then activates automatically.

Countries in the Question Pool

• At 0–9 correct answers, the pool contains 15 familiar countries; at 10–19 it contains 25, and at 20–29 it contains 40.
• From 30 correct answers, 20 randomly ordered countries are added every 10 correct answers.
• After 100 correct answers, all 195 countries are available and questions target only countries you have not yet answered correctly in this game. Distractors may still include completed countries.
• Correctly identify all 195 countries for WORLD COMPLETE and carry your remaining time into Expert Mode.

Flags to review

Weakness uses your last 10 answers, answer times and streak, with more weight on recent answers. A correct answer taking 3 to under 5 seconds counts as half a mistake; 5 seconds or more counts as a full mistake. A country leaves the list after 5 consecutive correct answers under 3 seconds, or at least 9 of the last 10 correct under 3 seconds including the latest answer. A mistake or slow correct answer can bring it back. Older correct answers without timing keep their previous treatment; countries without recent history use lifetime accuracy.

Practice

Unlocks after finishing 3 normal games by running out of time. Up to 50 countries are selected at the start, including up to 5 random undiscovered countries. The remaining places prioritize flags to review, with any gaps filled from discovered countries. New countries are added to your atlas when they actually appear as questions. Solve every target to enter Expert Mode with the same targets. No WORLD COMPLETE awards, bonuses, rankings, or normal records. Country history and review priority are updated.

Saved Results

• Your top 3 results are displayed, with up to 10 saved in this browser. Local results predating the current scoring rules are reset, while settings are kept.
• Your top result is protected automatically, and you can protect up to 5 results with the lock icon.
• Delete Results removes every result except those that are protected.

About Online Rankings

• Joining the rankings is optional and OFF by default. No account or email address is required. Turn Rankings ON to participate.
• Your My Page nickname and avatar, along with your score and rank, are public. If your nickname is blank, a Player-XXXXXX name is used.
• Do not use personally identifiable information or language that may make other users uncomfortable in your nickname.
• Results from games started with rankings ON are submitted when the game ends. Your past play history is not uploaded.
• Only your best score is kept for each period, and equal scores share a rank (for example, 1, 2, 2, 4).
• Rankings are separated by rule version. Scores from before this scoring update are not shown in the new rankings.
• Monthly rankings reset on the first of each month at noon Japan time (03:00 UTC). All Time records have no scheduled reset.
• To help keep rankings fair, the server checks answer histories and scores, prevents duplicate submissions for the same game, and limits excessive requests. IP addresses used for rate limiting are not stored in the ranking database.
• If a connection or validation issue prevents submission, your result is still saved in this browser. Failed submissions are not retried automatically.
• You can switch OFF at any time. Previously published records remain until you choose Delete online records, which removes your Flag Rush records from every ranking period. Deletion cannot be undone, but your local play history and best scores are kept.
• This browser stores the information needed to manage your online records. Clearing its saved data may leave you unable to manage previous records. If you also want to remove your public records, use Delete online records before clearing browser data.
