These figures come from the same corpus as the sweepstakes payout study, our running log of every cash-out we request with our own money.

The practical differences
Our records place Sportzino and WinBonanza in the same sister-site family, so treat this as a choice between two storefronts of one operation rather than two independent companies.
Both set the same redemption minimum, $50, so neither gives a small-balance player an easier exit.
We have a documented no-purchase entry route for Sportzino (mail-in postcard) but none confirmed for WinBonanza yet. That is a documentation gap on our side, not proof the route is missing.
Sportzino: minimum redemption $50. payout methods not confirmed yet. operated by SSPS LLC.
