Underdog Prediction Markets brings regulated event-contract trading into the familiar Underdog app, with a strong focus on sports, simple probability-based pricing, and access across most U.S. states.

Spinsly is a newer sweepstakes casino launched in 2026 and operated by Mamba Limited. It offers 740+ games, regular promotions, daily rewards, tournaments, and a 7-tier VIP program, with both Gold Coins and Sweeps Coins available. The welcome setup is one of its strongest features, with a $20 first-purchase offer worth up to 112,000 GC + 65 SC plus a Welcome Wheel. Banking is more limited, though, and Spinsly currently has no live dealer tables or live chat support.

Lady Lucka is a newer sweepstakes casino with free SC rewards, discounted coin packages, daily bonuses, and a VIP program. The site also stands out with a low 25 SC minimum redemption and a simple 1x playthrough requirement. In this review, I’ll cover Lady Lucka’s bonuses, games, banking, redemptions, safety, and overall user experience to see if it is worth playing.

Kalshi is one of the strongest options for anyone interested in prediction markets.

BangCoins is a newer sweepstakes casino with a large game library, flexible banking options, and a simple 1x playthrough requirement. The 50,000 GC + 1 SC welcome bonus is fairly modest, though, so I wanted to see whether the rest of the platform makes up for it.

DexyPlay is a sweepstakes-style social casino operated by UTech Solutions LLC, offering more than 1,600 games and a multi-level VIP program. When I registered, I received 300,000 Gold Coins without entering a promo code, but the offer included no Super Coins. That makes DexyPlay easy to test, although its welcome bonus provides no immediate redemption value.
