Terms of use

Effective November 1, 2026

These terms apply when you play Mines Rival in the app or at minesrival.com. Mines Rival is run by Sheffer Global LLC, Florida, USA ("we"). By playing, you agree to them. Questions: hello@minesrival.com.

Your account

You can play as a guest or sign up with an email. Keep your login to yourself; you're responsible for what happens on your account. You can delete it at any time in More → Settings → Delete account.

Fair play

No cheating: no bots, scripts, solvers, or help from other people or programs during rated games.
Be respectful: no offensive player names, club names or profile photos, and no harassment. Photos must be yours to share and must not show nudity, violence, hate or other people without their consent.
Other players can report a photo. A photo reported by several players is hidden until we review it, and we remove photos that break these rules.
One player per account, and don't deliberately lose games to change ratings.

We may reset ratings, remove names, or suspend accounts that break these rules.

Opponents

Online matches look for a real player first. When nobody at your level is searching, a computer-controlled opponent at your level joins so a game always starts.

Free Premium for invites

For the first 10,000 players: when 2 friends join Mines Rival through your invite link, you get 1 month of Premium free; when 5 join, 1 year. A friend counts once they've made an account and played 3 games. Only the person who sends the invite is rewarded. Invites must be real people; we may remove rewards earned with fake or duplicate accounts. Free time doesn't renew by itself and doesn't pause a paid App Store or Google Play subscription.

Premium

Premium costs $6.99 a month, or $59.99 a year (or the local equivalent shown at checkout) and gives unlimited lessons, puzzles and game analysis, with no ads. See Pricing.
You can buy Premium in the iPhone app (from Apple), in the Android app (from Google), or on minesrival.com. Premium is linked to your Mines Rival account, so it works on every device where you're signed in.
In the apps, payment is charged to your Apple or Google account when you confirm the purchase.
On minesrival.com, our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our website orders. Paddle provides all customer service inquiries and handles returns for those orders, under the Paddle Buyer Terms.
The subscription renews automatically at the same price unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
You can cancel at any time: for app purchases in your App Store or Google Play account settings; for website purchases through the link in your Paddle receipt email, or by writing to hello@minesrival.com. Cancelling stops the next renewal; Premium stays on until the end of the period you've paid for.
Refunds: see our Refund policy. App purchases are refunded by Apple or Google under their rules; website purchases by Paddle.
Deleting your Mines Rival account does not cancel the subscription; cancel it where you bought it too.

Free play and ads

The free version includes a set number of lessons and puzzles a day (currently 1 lesson and 3 puzzles, plus one more of each for watching a video), one game analysis a day for matches and computer games, free play, and the daily puzzle. Analysis of free play games is part of Premium. It shows ads, including an occasional short full-screen ad between games, puzzles, lessons and exercises, never in the middle of one. We may change what's free and what's Premium; Premium members keep what they've paid for until the end of their period.

The game

Mines Rival, its puzzles, art, coach and code belong to Sheffer Global LLC. We work to keep the game running, but it's provided "as is", and we can't promise it will always be available or free of errors. To the extent the law allows, our liability is limited to the amount you paid us in the last 12 months.

Changes

We may update these terms. If a change matters, we'll tell you in the game before it applies. Florida law governs these terms.
