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 check casinos

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

Licence and terms. We read each operator's licence record on the regulator's register and its published cashier, bonus and KYC terms, and quote the withdrawal window the operator documents. We do not fund accounts or time withdrawals, so no payout figure on this site is a measurement of ours.
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.
Provably-fair check. We check each site's seed-commitment scheme against the operator's own verifier and our calculator, and confirm the payout table matches the 0.99 ÷ probability curve for every mine count. We do not log play sessions or run device tests.
Dated third-party reports. Where a claim (payout speed in practice, support quality) cannot be read from the operator's own pages, we cite dated independent reports and attribute them.

Rankings are re-checked quarterly and after major site changes. We keep notes on every check 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 checks 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 documented withdrawal window that no longer holds? Email hello@minesmaster.com with a screenshot and we will re-check the source, usually within a few days. The fastest way to make this site better is to tell us where it is wrong.
