How we rank online casinos in Spain

What we rank

Our ranking of the best online casinos in Spain only includes operators licensed by Spain’s gambling regulator, the Directorate General for the Regulation of Gambling (Dirección General de Ordenación del Juego, DGOJ). To be eligible, an operator must hold the “Otros juegos” general license plus at least one casino singular license (roulette, blackjack, baccarat or slots), on a .es domain listed in the DGOJ register. As of October 1, 2026, 59 of the 78 operators in the register qualified.

We don’t rank or mention unlicensed sites, which Spain’s Gambling Act (Ley 13/2011) bans promoting. Our guide to whether online casinos are legal in Spain shows how to check a license.

How we built the shortlist

The DGOJ publishes no revenue or player figures per operator, so we shortlisted 12 of the 59 licensees on evidence anyone can check and researched each one in depth; the ranking is drawn from that shortlist. We used App Store rating counts from Apple’s Spain storefront, Google Play data for Spain (as support only, since Google may combine ratings from several countries) and Spain figures published by parent companies, checked on October 1, 2026, and gave casino-specific apps more weight than sports-first ones.

Some well-known brands missed the cut: casino licenses dating only from June or September 2026, too recent for a track record; small casino apps next to big sports apps; no roulette or blackjack license; a much smaller Spanish app footprint; or sister brands already covered in a shortlisted casino’s research.

The seven criteria

Each casino is rated from 0 to 10 on seven criteria. The licensing and support questions are Spain-specific; support covers the RGIAJ (Registro General de Interdicciones de Acceso al Juego), Spain’s national self-exclusion register.

The overall score is the weighted average, rounded to one decimal and shown on every review.

How DGOJ sanctions affect the licensing score

As of October 1, 2026, the DGOJ had published 219 sanction resolutions since 2021. None of the 101 “very serious” cases (99 for operating without a license) involved a shortlisted licensee; their cases were all “serious” (grave). We read each of those cases and weigh:

• Count: how many resolutions since 2021.
• Severity: a written warning counts for less than a fine, and breaches that put players at risk, such as letting self-excluded people play, count for more than administrative ones.
• Amounts: the fine imposed and the amount paid after legal reductions; for shortlisted brands, total fines imposed in 2021–2026 ranged from €10,000 to €1.21 million per brand.
• Recency: recent cases count more; some 2021–2023 advertising cases applied a 30-day bonus rule annulled in 2024.
• Exposure: larger operators have more players and more exposure, so we read records in that light and note self-reported cases.

A sanction doesn’t disqualify a casino on its own, and we never call an operator unsafe on that basis alone. Each review lists every case with its year, infraction type and amount.

Why bonuses never appear as bare amounts

Royal Decree 958/2020 on gambling advertising applies to websites and affiliates as well as operators (art. 2.a). Under art. 13.4, every bonus mention must state the minimum deposit, wagering requirement, time limit and whether you get withdrawable cash or bonus credit, so our tables have no bonus column: an offer appears only with all four terms and the date we checked it, or as subject to conditions on the operator’s site. We value bonuses on those terms, not the headline; see our casino bonus guide.

Where our information comes from

• The DGOJ: the operator register (licenses, dates and .es domains), sanction resolutions and market data.
• Operators’ Spanish sites: terms and conditions, payment pages and responsible-gambling pages.
• Spanish app stores: rating counts and averages, with the date we checked them.

Our reviews are research-based: withdrawal times and limits are what operators state, not results of our own tests. Under Spain’s Unfair Competition Act (Ley 3/1991, art. 10), comparisons must be objective and verifiable, so each rests on a source we can cite; when a detail can’t be verified, the review says so or leaves it out.

Updates and corrections

We re-check a casino when its DGOJ licenses or domains change, when the DGOJ publishes a sanction, or when the operator changes its terms or offer; every change is dated in the ranking’s update history. Our editorial policy explains how we research, how we make money and how to report an error.

The bottom line

We rank only DGOJ-licensed casinos, on seven fixed criteria, with sanctions read in context and bonuses shown only with their full terms; see the results in our ranking of online casinos licensed in Spain. Online casinos are for adults 18 and over. If gambling stops being fun, see where to get help in Spain.
