The Mountain Air is a UK review site about online casino jackpots. We read the bonus terms, cashier pages and help centres of the casinos we cover, write down what they actually say, and score each one against the same criteria. This page explains who we are, how we review and how the site is paid for.
Jackpot games get more attention than almost anything else in an online casino lobby, yet the rules around them are often the hardest to find. A progressive meter sits on the front-page banner, while the weekly withdrawal cap that decides how a large win is actually paid sits deep in the general terms. The Mountain Air exists to put those two things side by side.
We cover a short list of casinos in depth rather than a long list in passing. Every review follows the same structure: a verdict and score, an at-a-glance table, the welcome offer and its key terms, jackpot games, payments and withdrawal limits, verification, support and safer gambling tools. Our jackpot casino ranking brings those reviews together on one page.
Our aim is to help you understand a casino before you deposit, not after. In practice that means:
We never tell you a jackpot is due, and we never suggest that one casino will make you win more than another.
Each review starts with the operator’s own pages on the official site: the bonus terms, the general terms, the cashier and payment pages, and the help centre. The date we checked them appears at the top of every review. Where two pages give different figures, we say which page says what, or we use the stricter figure and say where it comes from.
We look for a dedicated jackpot section, named progressive and must-drop titles, in-house jackpots and network promotions such as Drops & Wins. A casino that lists its jackpot games clearly and lets you filter them does better than one where they are lost in a general slot lobby.
We do not score jackpot size or how often a top prize lands: both belong to the game, not the casino, and no casino can change them for you. We do check whether the lobby and the games show the live meter, the jackpot tiers and the rules for triggering the prize, so you can see what you are playing for before you stake anything.
We check that the site names the company behind it, that the verification steps are explained before you need them, and whether the operator states that its games and random number generators are independently tested. Missing basics are flagged in the review rather than skipped.
The headline figure matters less than the conditions behind it. For every welcome offer we note:
We list the deposit and withdrawal methods the cashier shows, the minimum deposit, the stated processing time and any daily, weekly or monthly limits. For jackpot players, the rule on how large wins are paid, in full or in instalments, is often the most important line in the terms, so we look for it specifically and say when it is missing.
We check whether the terms are dated and consistent with each other, how support can be reached and whether there is a clear route for complaints. We also read what players report elsewhere. When a point comes only from other review sites or forums and the official site does not confirm it, we say so and treat it as unconfirmed.
| Criterion | Weight | What it covers |
|---|---|---|
| Jackpot game range | 25% | Jackpot sections, named titles, network promotions, jackpot information shown in the games |
| Bonus terms and wagering | 20% | Wagering basis, expiry, maximum bet, win caps, jackpot exclusions |
| Payout limits and speed | 25% | Stated processing times, withdrawal caps, how large wins are paid |
| Operator transparency | 15% | Named company, dated terms, security and fair play basics, reputation |
| Mobile and support | 15% | App or mobile site, live chat hours, help centre depth, complaint routes |
The result is a score out of 10, shown in each review and on the ranking. A higher score means a casino did better on these criteria in our checks; it is not a forecast of what you will win. If one factor matters most to you, our lists of fast withdrawal casinos and casino welcome bonuses focus on exactly that.
The Mountain Air is written and edited by a small editorial team, and we publish as a team rather than under individual bylines. Each review is drafted from the casino’s own pages, then checked line by line: every bonus amount, wagering figure, deposit minimum, withdrawal limit and processing time is compared with the official site before the page goes live.
When a casino changes an offer or a reader points out an error, we correct the page and update the date at the top. We would rather say a detail is not published than fill a gap with a guess.
The Mountain Air is free to read. Some links on the site go to the casinos we review, and if you open an account through one of them, the casino may pay us a commission. That is how the site is funded. The commission never changes our scores or the order of our rankings, and the casino’s own terms always decide what you actually receive. Our disclaimer on affiliate links and liability sets this out in full.
Every casino we review is for adults aged 18+ only. Gambling is entertainment, not a way to make money, and jackpot games in particular are built so that the top prize is rare. Set a budget and a time limit before you play, and stop when you reach either one. If gambling stops being fun, free help is available:
National Gambling Helpline (GamCare): free and confidential, 24/7, 0808 8020 133
You can also turn to Gamblers Anonymous, GamAnon (for family and friends), Gordon Moody and NHS gambling clinics. Our safer gambling tools and support guide explains deposit limits, time-outs and self-exclusion in more detail.
We cannot help with casino accounts, payments or disputes: those go to the casino’s own support team. For anything about our content, such as a correction, a bonus term that has changed or a question about how we scored a casino, use the editorial team’s contact details.
No. We publish reviews, comparisons and guides. We do not offer games, take bets or deposits, or hold player accounts.
Each casino is checked against five weighted criteria: jackpot game range, bonus terms and wagering, payout limits and speed, operator transparency, and mobile and support. The total is shown as a score out of 10.
No. Casinos may pay us a commission when a reader signs up through our links, but that never changes a score or the order of a ranking.
Every review shows the date its terms were checked on the official site. We recheck a page when an offer changes or a reader reports an error, and the casino’s own terms always take priority over our summary.
We cannot access or change casino accounts, so contact the casino’s support team directly. If the problem is your gambling itself, call the National Gambling Helpline on 0808 8020 133, free and confidential, 24/7.
