Diego has spent over nine years analysing odds, football markets and sports bonus terms for the Spanish-speaking market. At Top LuckyGem he applies that same rigour to every operator he reviews, casino included.
Before moving into editorial reviews, Diego worked as a sports trader at a sportsbook, setting and adjusting odds in real time. That background lets him spot when a posted price drifts from a result's real probability, and judge on his own whether a sports bonus stacks up against the competition.
Since 2016 he has followed the Spanish sportsbook and online casino market, covering both DGOJ-licensed and international operators, and how each adapts its sports and bonus offering to the Spanish bettor.
Every review under his byline follows the same process: registration with a real account, at least one documented single bet and one accumulator (odds, stake, result), activation of the relevant bonus, and whenever possible a withdrawal request after a winning bet. Conclusions are written only afterward.
He pays particular attention to what other comparisons often miss: whether an operator's odds are truly in line with the market, how much of the promotional budget goes to betting versus casino, and what it practically means for an operator to lack a DGOJ licence. When a fact can't be verified firsthand, that's stated explicitly.
Top LuckyGem is funded through affiliate links, but no commercial agreement shapes the final score. An operator's negatives, including the absence of a DGOJ licence where relevant, are documented in the same detail as its positives.
When a reader registers with the recommended operator through our links, Top LuckyGem may earn a commission. This doesn't influence a review's critical conclusions.
