What is the ruling on the conditions required by free competitions—such as adding accounts, downloading applications, and inviting friends—to increase winning chances? And does the ruling differ if these conditions are essential for participation in the first place?

There is no objection to participating in free competitions where the participant does not pay money, even if it requires electronic promotion for the institution or website. This type resembles incentives and commercial promotional gifts. Some scholars view these forms as closer to gifts than to competitions, and that they are permissible according to Sharia as long as the promotion of the product and gaining fame are done according to Islamic guidelines.
