Zonko Casino Debuts in US Sweepstakes Market Casino By lines April 21, 2026 This content is for informational purposes only. Terms and eligibility vary by state. Zonko Casino entered the US sweepstakes market in 2026, adding another dual-currency platform to a shrinking legal map. Mamba Limited operates Zonko. CogniPlay powers the Zonko software stack. The Zonko platform uses the standard Gold Coin and Sweeps Coin model. What Zonko Offers Sweepstakes Players New Zonko accounts receive 3,000 Gold Coins on signup. The Zonko first-purchase bonus delivers 112,000 Gold Coins and 75 free Sweeps Coins for a $20 Gold Coin pack. Zonko also adds a fortune wheel spin for extra Sweeps Coins on that first purchase. Zonko runs slot-heavy content across classic and feature-driven titles. Players can trigger free spins, wild multipliers, and bonus rounds inside Zonko sessions. Zonko redemption requires Sweeps Coin wagering before prize conversion, matching industry standards. Zonko lacks a live chat channel, flagged by multiple reviewers as a support weakness. Zonko joins Dorados and Crown Coins in a Q1 and Q2 2026 launch wave. Dual-currency sweepstakes sites including Zonko face expanding US bans in 2026. Indiana outlaws sweepstakes casinos on July 1 under HB 1052. California banned the model on January 1 via AB 831.
