Make Your Mets vs Phillies Picks at Fliff

The social betting markets at Fliff closely resemble what you find at traditional online sportsbooks. So for MLB matchups such as Saturday’s Mets vs Phillies clash, you will be able to choose from hundreds of moneyline, totals, spreads and player/team props.

The big difference is that instead of using real money to make your picks, you do so using Fliff Coins and Fliff Cash. Whilst the former are strictly for fun, social betting, Fliff Cash can be exchanged for a real world prize if you meet the brand’s redemption requirements. Specifically, to redeem a price you need to have at least 50 Fliff Cash in your account and you need to have played through your balance.
