About GambGenius

Our mission

Most gambling comparison sites rank offers by the size of the bonus or the size of the commission. We rank them by what they are actually worth to you. Every guide we publish states the real house edge, every review shows the full terms, and every score follows a published methodology.

How a review is made

1. Terms read

   We read the operator's full offer terms and note every significant condition.

2. Value worked out

   We calculate total wagering and the estimated value with the published formula.

3. Facts listed

   Licence, payment methods, stated payout times and safer-gambling tools go into the review.

4. Scored

   Six weighted pillars give one score out of 10; equal scores are ordered by value, then name.

5. Re-checked

   Terms are re-checked when an operator changes them; each offer shows the date it was last checked.

What we do

• Read every term — we check wagering, caps, expiry and payout rules before we publish.
• Calculate value — expected value, total wagering and true spin value for every promotion.
• Teach strategy — from blackjack basic strategy to value betting, explained with honest maths.
• Promote safer play — every page links to responsible gambling tools and support.

What we will never do

• Rank a brand higher because it pays us more.
• Call an offer "exclusive" without a signed agreement that makes it so.
• Invent reviews, ratings, member numbers or "people playing now" counters.
• Use countdowns or "ends soon" pressure on offers or sign-up.
• Show offers to members who hide them, take a break or self-exclude.
• Sell your data, or tick a marketing box for you.

Editorial team

Our editors read the full terms of every offer and model each bonus's expected value before it is listed. Every page shows what you need to check our work: the full terms beside each offer, the formula behind every value, the date terms were last checked, and on guides the date of the next 90-day review. A guide is marked "Fact-checked" only when it lists the sources it was checked against. Named reviewers will be listed here once they are on record.

Free membership

Independence

GambGenius is free for readers. We earn commission from some operators when readers sign up through our links. Commercial relationships never influence scores, and we will not list an operator we would not use ourselves. Read our full affiliate disclosure.
