To register at 3 Reyes Casino, open 3reyes.casino, press “Autorización” and switch to the “Registrate” tab. The form wants an email address or a mobile number, plus a password. A third field takes an optional promo code. Nothing else is asked at that point: no name, no CURP, no INE.
We went through the form on 11 November 2026 without submitting it, so we did not open an account.
What the registration form asks
A note at the top says “Se puede usar para registrarse” (you can register with), followed by two tabs, E-mail and Celular. Below them sit the password and “Código de promoción si lo hay”. The casino’s FAQ says a confirmation link is emailed after you sign up. How phone registrations are confirmed isn’t explained anywhere.

The rules you accept
The “Reglamentos” are in English and few people read them, yet they’re what applies:
- only adults aged 18 and over may register;
- one person may hold one profile, and multiple accounts get suspended;
- software that gives an edge is banned, and staff and affiliates may not play;
- the player answers for following the gambling laws of their own country;
- the rules can change without notice, and you’re expected to read the casino’s emails.
ID checks: the FAQ and the rules disagree
The FAQ says documents are needed only in “absolutely extraordinary” cases. The rules say the casino can ask for photo ID when paying out, request a video call if it doubts the document, and suspend the account until you comply. Plan on the stricter version, because that’s the one used once money is on the line.
What about username accounts?
You can’t pick a username at sign-up; that tab only appears on the login form. If someone offers to “set you up” with a username, ask whose name the account is under and how you’d recover it. Without an email or phone attached, you depend on that person for everything.
Before you sign up, keep in mind that no 3 Reyes domain appears in SEGOB’s list of authorised sites, as covered in our review. Typing a promo code may also start a wagering requirement that blocks withdrawals for a while.
If you’d rather open an account somewhere else, you can see the offer from a commercial partner.
