Rhea Castillo is the Slots Editor at Gambling Slots Guide. She leads the team's work on slot site rankings, bonus checks and the explainers that sit behind them, and her name appears on the pages she writes or reviews. Her focus is simple: making sure what a US slots player reads here matches what the casino and the game actually say.
What does Rhea do on the site?
Rhea's work starts with the fine print. She reads each ranked casino's bonus terms line by line, noting the wagering multiple, what it applies to, how much slots contribute, how long the offer lasts and any cap on free spin winnings. Those notes become the figures on each casino card, along with the date she checked them.
She also checks slot info screens. When a review mentions a game's return to player or features, Rhea opens the game's help screen at the casino or the provider's own page and takes the figure from there. If neither source publishes it, the page says so.
Rhea tests the withdrawal flow described in each casino's terms: the verification steps, the minimum and maximum per payout, the stated time for each method and any rule that blocks a cash-out while a bonus is active. Payout rules carry the most weight in our scores, so this step matters most.
Finally, she maintains the rankings. When a term changes, she updates the figures, recalculates the score with the weights on our how we rate slots page, and moves the casino if the numbers say it should. Commissions never factor in.
How does Rhea write?
She writes for players who want the numbers before they deposit. Example figures are labelled as examples, offshore casinos are never described as US licensed, and no page promises a win. Every page carries the 21+ rule and a pointer to responsible gambling help.
