Ohayo Mines is a single-player minesweeper puzzle game, made by Ohayo, an independent developer. If something is broken, confusing, or you have an idea for the game, write to me directly — every message is read by a human.
The more of this you include, the faster it gets fixed:
The game's Settings screen also has ready-made “Report a bug”, “Suggest an idea” and “Improve a translation” links that open a pre-filled email.
Everything — scores, records, coins, unlocked cosmetics — is stored locally on your device. There is no account and no cloud sync, so progress does not transfer to another device, and deleting the app deletes it permanently.
By playing: every finished game pays out, milestones pay a bonus, and there is a daily reward. You can also watch an optional rewarded ad for extra coins. Coins buy cosmetics (themes, tile styles, sounds, app icons), optional conveniences such as an undo or a revive, and — in games that have several board sizes — a size you have not yet unlocked by playing. The games are single-player with no leaderboard, so nothing here is an advantage over anyone else.
No. The app has no in-app purchases at all. It is free and supported by advertising.
Ads need a working internet connection, and they are not always available in every region. Every ad-funded action in the game has an alternative: undo and revive can be paid for with coins instead, and anything that has no fallback hides itself rather than pretending to work. If a rewarded ad keeps failing, check your connection, then try again later.
Settings → Language. The game ships 36 languages and switches instantly, without a restart. By default it follows your iPhone's language.
Settings → Privacy inside the game, or iOS Settings → Privacy & Security → Tracking. Ads are shown either way — turning tracking off only makes them less relevant. In the EEA and the UK ads are never personalized.
Deleting the app removes everything it stored on your device. See the Privacy Policy for what the advertising and analytics providers process and how to reach them.
