Fliff โ€” Sweepstakes Casinos, Grades & Complaints

Fliff Inc ยท Pennsylvania, USA

Fliff Inc operates 2 sweepstakes casinos. See every brand, its SweepsGuard grade, and the operator's complaint track record.

Fliff, Inc. is a venture-backed company headquartered in King of Prussia, Pennsylvania, co-founded by Matthew Ricci and Mario Dodev. Its original platform, Fliff, launched in 2019 and operates as a sweepstakes sportsbook rather than a casino, using the dual-currency model applied to sports wagering. Sidepot followed in early 2025 at sidepot.us, running Gold Coins for free play and Sweeps Cash redeemable one-to-one for dollars.

Overview

Fliff is a sportsbook rather than a casino, and one of the older platforms in the sweepstakes model, running since 2019 with conventional venture backing behind it. The complaint record is short and heavily weighted toward one very large item.

Where it is worth watching

2 cases have been filed with SweepsGuard, both against Fliff and both in August 2026. 0 ended with money back and 2 are unresolved. One is an unpaid withdrawal the operator responded to and refused. The other, the largest case on record against this operator at $42,262.89, drew no response at all. A short case list is a small sample; a five-figure balance going unanswered is not a small event.

Player guidance

Redeem in regular, moderate amounts rather than letting winnings accumulate. The published record here contains no example of a large balance being paid out after a dispute, and one clear example of a very large one going unanswered.
