Play uses two currencies. Gold Coins are for standard play and can't be redeemed, while Rainbet Cash (RC) can go toward prizes once it has been played through. Coin packs are sold for crypto, through a connected wallet, or by Visa, Mastercard, Apple Pay and Google Pay, and the Sweeps Rules also offer a free postal entry for RC, so no purchase is necessary.
The lobby lists 4,376 games from about 40 studios, KA Gaming, BGaming and Hacksaw among them. There are also 66 live games and 15 in-house Rainbet Originals with seed and verifier tools. The site is open in 27 states.
Rainbet US shares its name with Rainbet, the crypto casino brand, which is listed under a different company. Sweepstone's pages don't say how the two are connected, and the owners of Sweepstone Ltd are not disclosed.
Coin packs, redemption limits and the verification levels are covered in our Rainbet US Casino review, and you can compare it with other sweepstakes casinos in the US.
