Duuloo Prediction Challenge Rules
Last updated: March 19, 2026
These rules describe how the Duuloo prediction competition is intended to work for the current World Cup challenge shown in the app.
Entry and Eligibility
- The core prediction challenge is free to enter.
- You must use a valid Duuloo account to submit predictions.
- Duuloo may limit, suspend, or remove entries from accounts that appear fake, automated, duplicate, abusive, or otherwise in violation of the app rules.
How Predictions Work
- You may submit one prediction per account per match.
- You may update your prediction until the lock time. The latest saved prediction before lock is the one that counts.
- Predictions are made by choosing an exact score for the home team and away team.
Lock Time
Predictions lock 10 minutes before the scheduled kickoff time, based on Duuloo server time and the kickoff time stored for that match in the app.
If a kickoff time changes before lock, the lock time may move with the updated kickoff. If a kickoff changes after lock, predictions stay locked unless Duuloo decides to void or reopen the match under separate published guidance.
Public Transparency
- Exact predictions stay hidden until the match locks.
- After the cutoff time, revealed predictions may become visible to other users through match pages, public predictor pages, and the leaderboard experience.
- Public handles and display names may be shown with revealed picks so other users can verify the competition history.
Scoring
- Exact score: 100 points.
- Correct goal difference: 50 points.
- Correct result home win, away win, or draw: 30 points.
- 3-match streak of correct results: 100 bonus points.
- These points stack. For example, an exact score can also earn goal-difference and correct-result points.
Overlapping Streaks
Streak bonuses can overlap. If you correctly predict matches 4, 5, and 6, you earn one streak bonus. If you also correctly predict match 7, you earn another streak bonus for matches 5, 6, and 7.
Official Match Result Used for Scoring
Duuloo scores predictions using the official home and away score recorded in the app from its match data source for the relevant match result.
Penalty shootouts are not scored as a separate bonus unless Duuloo clearly publishes additional match-specific rules before that match locks.
Leaderboard and Ties
The in-app leaderboard reflects the points calculated under these rules. If Duuloo offers a prize that requires a single winner and multiple participants are tied, Duuloo may apply additional published tie-break criteria before a prize is awarded.
Voids, Errors, and Exceptional Cases
- Duuloo may void, delay, correct, or rescore a match if there is a data issue, material outage, duplicate fixture, rule error, or integrity issue.
- If a match is abandoned, significantly altered, or otherwise becomes unsuitable for normal scoring, Duuloo may mark predictions as void.
Prizes and Premium
Any sponsor-funded prize, if offered, will be subject to separate official prize details and any required local restrictions. Premium subscriptions or paid features do not automatically grant better odds, extra entries, or special scoring unless Duuloo explicitly publishes that change in official rules.
Fair Play
- No fake-account farming, automated submissions, identity misrepresentation, abuse of bugs, or manipulation of leaderboard data.
- Duuloo may investigate suspicious activity and disqualify or remove entries when needed to protect the integrity of the competition.
Changes to the Rules
Duuloo may update these rules before or during the tournament if needed for clarity, legality, fairness, or technical reasons. Material changes should be posted in the app before they are applied going forward.
