What Sisse does

Sisse operates Prowin Casino, a Curaçao-licensed online casino platform distributed through its own website at sisse.ro and targeting adult players in Romania. The platform aggregates over 5,000 games from more than 15 third-party studios spanning slots, live dealer tables, and crash/instant games, with tier-1 providers including Pragmatic Play, Evolution Gaming, NetEnt, Play'n GO, and Microgaming integrated alongside specialist crash-game developers such as Spribe, Smartsoft Gaming, and BGaming.

The technology stack is a web-based, mobile-optimized interface with no native mobile app, relying on browser-based access across desktop and mobile devices. Payment processing supports bank cards (Mastercard), e-wallets (Neteller, Skrill, ecoPayz, PayPal, Apple Pay), European regional rails (Giropay, Sofort, Banklink), and cryptocurrencies (Bitcoin, Bitcoin Cash, Ethereum), with a 20 RON minimum deposit, 50 RON minimum withdrawal, and 1–24 hour withdrawal processing. Localization is limited to Romanian and English with RON as the primary currency.

Revenue is generated through house edge on player wagers across the game portfolio and through net transaction economics on player deposits, under a free-to-play, deposit-based wagering model with no subscription or membership fees. The go-to-market is direct-to-consumer via SEO and the sisse.ro web property, supplemented by Google review presence and affiliate referral channels. The company is privately held with 1–10 employees, no disclosed funding, no disclosed revenue, and ownership and management team are not disclosed in the source material.
