Enroll with Apple as an organization
For your iOS apps, please enroll as an organization (not as an individual) with Apple and submit your app under that organization. Apple requires competition skill-based games to be submitted by organizations. If you submit games as an individual, your app will be rejected.
Please refer to Apple's docs for enrollment information.
Become a Samsung Partner
Please note that if you don't register as a Samsung Partner, then you will be required to integrate the SDK and have in-app purchases within your game. Therefore, to simplify the submission process to the Samsung Galaxy Store, please enroll your Android apps as a Samsung partner.
Please refer to the Samsung docs for more details.
