Winorio review: a 2021 casino with a Costa Rica licence, two studios and a very large welcome package
2021 Founding year · On our list since 3 Apr 2025 · Established casino
Winorio has run since 2021 and states a Costa Rica licence, which is a business licence with no gaming regulator behind it. It takes pounds, euros and Bitcoin, with Visa, Mastercard, Apple Pay, Google Pay and Bitcoin for deposits.
Our data lists only two studios, Yggdrasil and Zillion, and slots and roulette as its game types. Its welcome package is far larger than that lobby suggests.

Short answer
Should you try Winorio?
Winorio is hard to recommend. A very large bonus on a casino with a thin game list and no gaming regulator calls for the full terms before any deposit, and our country data does not confirm which countries it accepts. If you try it, deposit only what you would lose on a test.

Licence on the regulator's register
A logo in the footer proves nothing. The licence number and company name must appear on the regulator's own register, with the same domain.
Copy the licence number from the casino's footer and search it on the regulator's public register. Some regulators publish no searchable register; then ask support for the certificate.

Welcome offer
What €7,000 + 200 Free Spins is worth
A headline this large is almost certainly spread over several deposits, and most players only ever claim the first part, so the worksheet starts at €200. The wagering is not in the offer we list, so set it from Winorio's bonus terms.

WorksheetSet the bonus part you would claim. The default is a first-deposit example, not the casino's terms.
You must bet €7,000 before the bonus turns into cash. At 96.0% RTP that costs €280 on average, so the bonus is worth about -€80.

What is the Winorio welcome bonus?
The offer listed is $8,000 + 200 FS. Read the bonus terms for the wagering, the maximum bet while it is active and the games that count, since the worth of a large headline depends on all three.

Responsible gaming
Play only if you are 18+ and it stays fun
These rules apply on every page of this site. A casino in its first year has less history to judge it by, so the limits matter more.
Adults only, everywhere
You must be 18 or older, and older in some countries. A casino can ask for ID before your first withdrawal, and new casinos often do.
Responsible gamingStart small with an unknown casino
Deposit an amount you would accept losing to a failed withdrawal, and request a small cash-out early to see how the casino handles it.
