Every other Minesweeper on Android is either a privacy nightmare stuffed with ads and trackers, or a bare-bones port that looks like it was built in 2009. This one is neither. No ads. No permissions. No analytics. No internet. Just the game. Built with Jetpack Compose and Material 3 — it looks and feels like a first-party Google app. Material You dynamic colour adapts the entire palette to your wallpaper on Android 12+. The grid always fills the screen. Cells scale to any device. No zooming, no tiny tap targets. <b>Three modes that are mechanically distinct, not just bigger grids</b> • <b>Easy</b> — 9×9, classic rules, guaranteed safe first click, full chord support • <b>Medium</b> — 12×12, higher mine density, 5-minute countdown, only your clicked cell is safe at the start • <b>Hard</b> — 14×14, no safe start, chord disabled, 3-minute countdown, and <b>fog of war</b>: revealed cells fade out after 6 seconds and you must hold the entire mine map in your head Fog of war is a novel mechanic that does not exist in any other Minesweeper app. <b>Polish</b> • Ripple flood-fill — empty areas reveal outward in animated waves • Spring bounce on every cell open and flag placement • Screen shake on game over • LED-style mine counter and timer, blinks red under 30 seconds • Haptic feedback on every interaction • Deep-space dark theme with vibrant number colours <b>100% free and open source</b> — GPLv3, no ads, no tracking, no analytics.
