5. SUBMISSION REQUIREMENTS AND RESTRICTIONS

All submissions must comply with the following:

1. The Dive must be created using the MotherDuck Dives platform.
2. The Dive must be the original work of the entrant. If the Dive incorporates third-party data, the entrant is solely responsible for ensuring they have all necessary rights and permissions to use such data.
3. The Dive must not contain any content that is:
   • Obscene, offensive, defamatory, or otherwise objectionable;
   • Infringing upon any third party's intellectual property rights, privacy rights, or publicity rights;
   • In violation of any applicable law or regulation;
   • Containing malware, viruses, or harmful code;
   • Deceptive, fraudulent, or misleading.
4. The Dive must remain publicly accessible through the Announcement Date at minimum. Entrants who remove or make their Dive inaccessible before winners are announced may be disqualified.

Sponsor reserves the right, in its sole discretion, to disqualify any submission that violates these requirements.

6. JUDGING CRITERIA AND WINNER SELECTION

Winners will be selected in three (3) categories:

Category 1: Best Overall

Selected by a panel of judges appointed by Sponsor ("Judging Panel"). The Judging Panel will evaluate shortlisted submissions based on the following equally weighted criteria, each scored 1-5 (20 points max per judge):

• Narrative: Does the Dive tell a clear story or answer a clear question? Does it guide you from "what am I looking at" to "here's what matters"?
• Design: Visual composition, typography, color, layout. Does form serve function? Is it readable and accessible?
• Interactivity: Does it use the medium well? Filters, drill-downs, and exploration that earn their place.
• Clarity: Does the takeaway land? Can you understand what you're looking at without explanation?

Category 2: Most Creative

Selected by the Judging Panel based on the following equally weighted criteria, each scored 1-5 (15 points max per judge):

• Originality: Is the concept, dataset, or approach something you haven't seen before?
• Ambition: How far did they push it? Did they take a real swing?
• Execution: Does it actually work? Creative intent only counts if the data still lands.

All three (3) judges score all shortlisted entries on both rubrics. Highest total score wins. In the event of a tie in any panel-judged category, the Judging Panel will deliberate and select a winner.

Category 3: Community Favorite

Determined primarily by community upvotes cast during the Submission Period. To participate in voting, individuals must create a MotherDuck account and log in. The voting mechanism ensures that each registered MotherDuck account holder may cast only one (1) upvote per submission. Self-voting is permitted. Sponsor reserves the right to exercise final discretion in the selection of the Community Favorite winner, including but not limited to adjusting results to account for suspected fraudulent voting, bot activity, or other manipulation. Sponsor's decisions regarding vote validity are final.

A single submission may win in only one (1) category. If a submission would otherwise win in multiple categories, it will be awarded the prize of highest value, and the next-highest-scoring eligible submission will receive the other prize. The decisions of the Judging Panel and Sponsor are final and binding in all matters relating to the Contest.

7. PRIZES

The following prizes will be awarded:

All winners will also receive a MotherDuck swag box (ARV: approximately $75 USD each).

Total ARV of all prizes: approximately $2,325 USD.

Prizes are non-transferable and may not be redeemed for cash, except at Sponsor's sole discretion. Sponsor reserves the right to substitute any prize with a prize of equal or greater value (including a cash equivalent) if the advertised prize becomes unavailable for any reason, including but not limited to shipping restrictions to the winner's country of residence. Sponsor will cover standard shipping costs for physical prizes to eligible jurisdictions, but as noted in Section 9, winners remain responsible for any customs duties or import taxes.

Each eligible entrant may win a maximum of one (1) prize. Prize details and availability are subject to change at Sponsor's discretion.

8. WINNER NOTIFICATION AND VERIFICATION

Potential winners will be notified by email at the address associated with their MotherDuck account on or about the Announcement Date. Each potential winner must respond to the notification within seven (7) business days of the date the notification is sent. If a potential winner does not respond within this period, or if the notification is returned as undeliverable, the potential winner will be disqualified and an alternate winner may be selected.

Before receiving a prize, each winner may be required to:

1. Complete and return an affidavit of eligibility, a liability release, and (where permitted by law) a publicity release;
2. Provide valid government-issued identification to verify identity and age;
3. Complete tax documentation, including IRS Form W-9 (for U.S. residents) or Form W-8BEN (for non-U.S. residents), as applicable.

Failure to complete any required documentation within the specified timeframe will result in forfeiture of the prize.

9. TAXES

All federal, state, provincial, local, and foreign taxes, duties, customs fees, and any other costs or expenses associated with the acceptance and use of a prize are the sole responsibility of the winner. For U.S. residents, prizes valued at $600 USD or more will be reported to the Internal Revenue Service on Form 1099-MISC. Sponsor may be required to withhold taxes from prize values as required by applicable law.

International winners are solely responsible for any import duties, customs fees, value-added taxes, or other charges imposed by their country or jurisdiction of residence related to the receipt of a prize. Sponsor is not responsible for, and will not pay, any such charges.
