How do you help us manage legal obligations regarding chance-based contests?

In my country it's easier to organize skill-based contests, can we therefore add Tiebreaker questions to be answered for the contest?
We must also provide detailed terms and conditions, including:
- Entry Requirements: Eligibility criteria, such as age and residency restrictions.
- Participation Rules: How to enter, deadlines, and any tasks or questions involved.
- Prize Details: Description of the prize, its value, and how it will be awarded.
- Data Usage: Information on how participants' data will be handled in compliance with GDPR.
- Dispute Resolution: Procedures for handling any disputes or issues that may arise.

Thank you.
