Our Standards

The Slapkong review desk runs on three principles that take precedence over everything else, including the revenue the site earns from the operator's affiliate programme. First, we write about what we have actually done. A page that explains how a withdrawal arrives says what we deposited, with which method, how long the review took, and on which day — we do not describe steps we have not run. Second, we do not clean up what the operator did. When a bonus has a fourteen-day expiry, our page says fourteen; when a wagering requirement is x45, our page says x45; when a payout took a day longer than the headline suggests, the page carries the day. Third, when we are not sure, we say so. If an operator document is unclear on a cashier limit, if a licence detail is missing from the public register, if the live chat does not know the answer, we write that the figure is unverified rather than invent one. Readers who come to a review desk want a clean read of the operator, and that is only possible when the desk is willing to disappoint commercially — by publishing a flaw, or by not publishing a figure the operator wants shown — in exchange for keeping the trust that makes the review useful in the first place. Everything else in this document, from fact-checking to the way we label sponsored content, follows from these three starting points. The desk's editor-in-chief owns the final call on every published page and signs off any change to this document; the sign-off date lives at the bottom of the editorial guidelines page itself.

Every review on this site goes through a two-step fact-check before publication, and through a quarterly recheck afterwards. In the first step, the author verifies each hard figure against a primary source: the operator's own terms page for the bonus match percentage and wagering, the Curaçao licensing register for the licence number, the cashier popup in a logged-in Slapkong account for the deposit minimum, and a timestamped screenshot of a withdrawal for the payout window. Secondary sources — comparison sites, affiliate newsletters, operator press releases — never count on their own, and if a secondary source disagrees with a primary one, the primary one wins. In the second step, a second editor repeats the lookup on at least a third of the hard figures at random, and signs off that the page is ready; the sign-off record stays on the editor's computer for a year. The quarterly recheck revisits every review on the site: the author reopens the operator's terms page, pulls the current cashier figures, runs a short deposit and withdrawal if the previous one is older than six months, and resets the 'updated on' date at the top of the review. If a figure has changed, the old number stays visible in the page's revision history, so a reader who remembers the old value can see what moved.

No page on this site that reviews a casino product is paid for by the operator being reviewed. The Slapkong review, the bonus pages, the deposit-and-withdrawal guide and the mobile-app page are all written on the editorial budget of the desk and are not previewed or approved by Slapkong before publication. The desk does earn a share of revenue when a reader clicks through and signs up at Slapkong — that is how most review sites keep the lights on — and this is disclosed in the footer of every page, in the first paragraph of the main review, and in this document. On the rare occasion that the desk accepts sponsored content — for example, a short briefing on a regulatory update written by a specialist law firm, or an industry analysis written by a software supplier — the sponsored piece sits on its own URL, is tagged 'sponsored' at the top of the page, and is not linked from any editorial review. Sponsored pieces are never used to shift the ranking of a casino, to delay a critical review, or to recycle operator press releases as editorial. If a reader believes a page on this site is not following these rules, the editorial inbox listed in the footer is the right place to write; a complaint received in writing is answered in writing by the editor-in-chief within five business days.
