Fliff Inc

Fliff Inc. is the King of Prussia, Pennsylvania company behind Fliff, a social sportsbook that uses Fliff Coins and Fliff Cash instead of Gold Coins and Sweeps Coins. Maryland's regulator also wrote to it as "Sidepot by Fliff". Fliff is a sports picks app, not a casino, but officials in four states have acted against it. This page covers the company, both brands, where Fliff works and those regulator actions.

Who Fliff Inc. is

The Fliff Terms of Service (last updated 13 Aug 2025) define the company as "Fliff Inc. of 840 First Ave, STE 400, King of Prussia, PA 19406 and any related companies". The site footer carries a 2025 Fliff Inc. copyright. Players must be 18 or older, or the age of majority where they are if that is higher. The terms are governed by Pennsylvania law, and US players are bound by an arbitration clause under the Federal Arbitration Act.

Fliff has two currencies. Fliff Coins are for fun play and are bought or claimed free. According to our review, Fliff Cash cannot be bought; it comes free through sign-up, timed claims, mail-in requests and bonuses on Fliff Coin packs. Fliff Cash won from picks can be redeemed for prizes.

How we know who runs it

  • The terms name Fliff Inc. at the King of Prussia address.
  • Maryland wrote to "Fliff Inc., 840 First Avenue, Suite 400, King of Prussia, PA 19406" about "FLIFF Inc. d/b/a Fliff, Sidepot by Fliff" [1].
  • Illinois wrote to "Fliff, 823 Congress Ave, Austin, Texas" and emailed Fliff's legal and support addresses [2]. The email domain matches Fliff's own site.

Brands and our reviews

Fliff scores 7.5/10 in our review. The sign-up offer is 5,000 Fliff Coins plus 1 Fliff Cash after identity checks. Fliff Cash redeems at $1 each from 50 Fliff Cash, by Skrill or bank transfer. The mail-in route gives 5 Fliff Cash per request.

Sidepot by Fliff is named in the Maryland letter [1] and on the New York list as Sidepot [4]. Our Fliff review calls it a social casino, citing a third party. We have not reviewed Sidepot and have not read its terms.

Where Fliff is available

The terms exclude Washington and Idaho for Fliff Coin games, along with US territories, Quebec and anywhere outside the US and Canada. Fliff Cash has its own, longer state list in the in-app Sweepstakes Rules, which we have not read. Our review found that published lists for Fliff Cash differ from one site to the next.

Oklahoma is not mentioned in the terms we read on 27 Oct 2026. Oklahoma's SB 1589 takes effect on 1 Nov 2026 [5]. Check the in-app rules before playing from Oklahoma.

Regulatory history

  • Maryland: on 3 Jun 2025 the Lottery and Gaming Control Agency wrote to Fliff Inc. d/b/a Fliff, Sidepot by Fliff. It said Fliff was offering online gaming in Maryland without legal authority, and asked it to confirm within 10 days that it would stop offering casino games there [1].
  • New York: on 6 Jun 2025 the Attorney General named Fliff and Sidepot among 26 platforms ending the sale of sweeps coins in the state [4].
  • Arizona: on 15 Aug 2025 the Department of Gaming announced cease-and-desist orders to four operators. It listed "Fliff Online Gambling" under event wagering sportsbooks. It said the operations were alleged to break state law, including promotion of gambling, illegal control of an enterprise and money laundering, all felonies [3].
  • Illinois: on 4 Feb 2026 the Gaming Board wrote to Fliff about "sports wagering" offered to Illinois users. The observation date in the letter reads "January 0, 1900", which looks like a template error [2].

We did not find Fliff on the Tennessee Attorney General's December 2025 list.

Where the sources disagree

  • Address. The terms and Maryland use King of Prussia, Pennsylvania [1]. Illinois used 823 Congress Ave, Austin, Texas [2]. We have not found a Fliff document that gives the Austin address.
  • What Fliff is. Our review describes Fliff as a social sportsbook, not a state-licensed sportsbook. Arizona called it an event wagering sportsbook [3], Illinois called it sports wagering [2], and Maryland asked it to stop casino games [1].
  • Terms date. The terms we read were last updated on 13 Aug 2025, before the Arizona and Illinois actions.
