About
Minesweeper is a logic puzzle game genre, usually played on personal computers, in which players clear a grid of tiles without detonating hidden mines by using clues about neighboring mines. Mines3D is an Android Minesweeper variant played on a two-layer grid, available on Google Play and F-Droid under the GPL-3.0 license. It has five modes, from 5x5x2 with 7 mines up to 15x15x2 with 90 mines.
How it differs from the original
Each cell counts mines in its four horizontal neighbors plus the matching cell on the other layer, and a button switches between layers. Mines are marked with a long press and cells are revealed with a double-tap.
Getting started
Install it from Google Play or F-Droid, or build it in Android Studio. It requires a device running Android newer than 4.4.
