A mirrored Hexsweeper sphere — six neighbors, first dig always safe. Covered faces hold the reflection; cleared faces become matte wells.
Clear every safe face. Mirror means covered; matte means cleared; scarlet means flagged. Numbers count mines among the six touching neighbors.
Tap outside the sphere to open the center menu: reset, undo, flag mode, board size, light or dark, warning style, and drag inversion. Progress autosaves through refresh. Reset or size change starts a new sphere (no confirm).
