About Us

thezombiunicorn.com is an independent editorial project for US players who want to find the best bonus buy slots and the social & sweepstakes casinos where you can buy the bonus feature instantly. One goal: clear, verifiable information on welcome coins, slot providers, feature-buy support, prize redemption, and state availability — with no hype.

How we work

Every sweeps casino in our ranking is assessed on five objective factors:

• the value of the welcome Gold Coins and free Sweeps Coins;
• whether the slots support feature buys (Bonus Buy);
• the game providers and catalog depth (Pragmatic, Hacksaw, Nolimit, NetGame and more);
• how easily Sweeps Coins redeem for prizes;
• state availability and the overall play experience.

Editorial independence

We are funded by affiliate commissions: if you sign up through our links we may earn a commission, at no extra cost to you. This does not change our verdicts — the ranking reflects our assessment, not commercial deals. Coin offers change often, so always confirm the details on the operator's own site.

A note on the sweepstakes model

The casinos we review are social / sweepstakes casinos, not real-money gambling sites. You play Gold Coins for fun, or use Sweeps Coins — obtainable free and no purchase necessary — which can be redeemed for prizes. They operate under US sweepstakes law and are available in most states, with some exclusions (each brand lists where it is not offered). You must be 18+.
