Callum Rourke, Payments & Account Security Analyst

What Callum Rourke writes about

Callum Rourke writes and maintains the guides on r855casino.com. His beat is the part of an online casino most reviews skip: the cashier and the account. That means how a deposit through a local rail such as ABA PAY, Wing or a KHQR code is supposed to travel, why an account kept in riel behaves differently from one kept in dollars, what an operator is checking when a withdrawal sits in "pending", and how players lose money without ever placing a bet — to fake mirror sites, chat-app "agents" and requests for one-time codes.

He also reviews the game, bonus and betting pages of the site, always from the same angle: what each one means for the money in the account and for the person who owns it.

Areas of focus

• Local payment rails in Cambodia — ABA PAY, Wing, Bakong / KHQR — and how to recognise a genuine payment request
• Riel and US dollar accounts, conversion and how to read a transaction history
• Verification (KYC), proof-of-payment requests and withdrawal statuses
• Account protection: passwords, two-factor log-in, SIM and e-mail security
• Fraud patterns: phishing pages, fake apps, "unlock fee" messages, doctored screenshots
• Deposit limits, time-outs and self-exclusion tools

How the guides are put together

Every page starts from two lists. The first holds facts about Cambodia — the gambling law and its regulator, the currencies, the payment systems, the help services — each with a source and a date, taken from the site's fact file. The second holds facts about R855 itself, and here the rule is strict: a limit, a fee, a payout time or a bonus percentage appears only if it can be confirmed, and because cashier settings differ from one account to another, the page usually tells you where to read the figure instead of printing one. When a statement could not be confirmed at its source, it stays out.

Callum does not claim to have played, deposited or withdrawn at R855, and no page on this site invents a test result, a timing or a player review. That is a deliberate choice: an invented figure looks reassuring and fails the reader exactly when it matters.

What he is not

His expertise is practical rather than credentialled: he is not a lawyer, an auditor, a certified security expert or an employee of any casino operator, and nothing on this site is legal or financial advice. Where a page depends on the law, it names the law and the date of the information. He never asks readers for passwords, codes, ID photos or money — if someone using his name does, it is a scam.

Editorial rules

r855casino.com is independent of the operators it covers. Coverage is not sold, no operator previews a page, and a commission earned through a partner link never changes an assessment. Weak points are written down when they are found. Corrections that can be verified are made promptly; send them to info@r855casino.com with the page address.

Responsible gambling

Everything here is written for adults (18+). Cambodian law does not allow Cambodian citizens to gamble, and online operations at casinos were announced as suspended from October 2026. For anyone who does play where it is permitted: set the limit before the first deposit, not after a loss. Help options are on the responsible gambling page.

About the author's sources

The Cambodian facts behind these pages come from primary or well-sourced references — the National Bank of Cambodia's Bakong pages, the banks' own descriptions of their services, legal updates on the LMCG and news reports of the 2019 and 2026 decisions — and each entry in the fact file carries the date it was last checked. Where a source could not be opened or read in full, the entry is marked unconfirmed and is not used as a statement on the site.
