About the Company

Fliff

Online sports-prediction social platform with rewards

Fliff runs an online sports prediction platform with a social sportsbook that lets users make sports picks for fun and compete for rewards. It uses two in-system currencies: Fliff Coins, which players use to play games and can be claimed every two hours or bought but cannot be transferred outside the game or redeemed for prizes, and Fliff Cash, which can be earned for free as a bonus and sometimes through coin packs or other entries. The platform also runs sweepstakes-style promotions to award prizes and promote coin sales, requiring identity verification to participate and redeem prizes. It operates in the United States except Washington, with additional sweepstakes exclusions for Hawaii, Idaho, Nevada, and Tennessee. Its business model centers on selling Fliff Coins and integrating sweepstakes to drive engagement and revenue, while differentiating itself through its social, coin-based gameplay and prize-driven experiences.
