A sweepstakes is a promotional event where real prizes are given away, and participation doesn't require any payment or extensive effort. This is usually achieved by offering an alternative method of entry, ensuring that everyone can participate without spending money. This concept is often summarized by the phrase "no purchase necessary," which is commonly found in the fine print of promotions by major brands.

In the realm of gaming, sweepstakes gaming refers to games that offer real-world prizes without requiring players to spend money. This is made possible by providing an alternative method of entry, where players can obtain virtual currency for free, allowing them to potentially win real prizes without making a purchase.
