The practical differences
Start with what the branding hides: both casinos are operated by Mamba Limited. You are not choosing between two companies, you are choosing between two storefronts of one, so the deciding factors are the terms and the evidence on this page, not the logo.
Both set the same redemption minimum, $100, so neither gives a small-balance player an easier exit.
Both keep a documented no-purchase entry route open (mail-in postcard), which is the baseline a legitimate sweepstakes has to meet.
Spinsly: minimum redemption $100. pays via bank_transfer. operated by Mamba Limited.
1uckyduck: minimum redemption $100. payout methods not confirmed yet. operated by Mamba Limited.
