About MinesMaster

MinesMaster is an independent, English-language guide to one game: Mines, the 5×5 gem-and-mine original popularised by the big crypto casinos. We do three things — rank where to play it, explain its math honestly, and provide a free calculator that makes the odds impossible to misunderstand.

How we test casinos

Every site in our top 8 goes through the same process before it earns a position, most recently in June 2026:

• Real deposits and withdrawals. We fund an account with our own crypto, play, and time a real withdrawal from request to on-chain confirmation.
• Payout-table verification. We compare the casino's displayed Mines multipliers against the 0.99 ÷ probability formula. Sites that shave more than the standard 1% are excluded, whatever they would pay us.
• At least 200 rounds per site across low, medium and high mine counts, on desktop and mobile, plus a check of seed rotation and provably-fair verification.
• Support test. One real question to live chat, response time and quality noted.

Rankings are re-checked quarterly and after major site changes. We keep notes on every test and correct published numbers quickly when readers spot drift — the payout math is public, so you can audit us with the calculator at any time.

How the site makes money

Affiliate commissions, openly: when you join a casino through one of our links, the casino pays us a fee. It costs you nothing, changes none of your odds or bonuses, and — this is the part we are strict about — does not buy a ranking. The order of our list is set by the test results above; several sites with affiliate programs did not make the cut, and our number one would stay number one if its program closed tomorrow.

What we are not

We are not a casino, we hold no player funds, and we sell no “winning systems” — our strategy guide opens by telling you the house edge cannot be beaten, which is not a great sales pitch but has the advantage of being true. Gambling content here is for adults (18+) and for entertainment value only. If play stops feeling like entertainment, our responsible gambling page lists free, confidential help.

Corrections and contact

Spotted a multiplier that does not match a live payout table, a limit that changed, or a withdrawal time that no longer holds? Email hello@minesmaster.com with a screenshot and we will retest, usually within a few days. The fastest way to make this site better is to tell us where it is wrong.
