Spin Rush turns website visitors into email subscribers with a slot-machine game. Visitors spin to win a prize — a coupon, free shipping, or a WooCommerce gift — then enter their email to claim it. Everything runs server-side (RNG, win logic, anti-cheat), so results can't be faked from the browser. 7 prize types, 5 email integrations (Mailchimp, ActiveCampaign, ConvertKit, MailerLite, Brevo), webhooks, and a stats dashboard. Play the live demo — no signup.
