Reveal cells and avoid sea mines, just like standard Minesweeper.
Right-click to place/remove a flag on desktop, or switch to Flag mode on mobile.
Rockets launch from the flank, land imprecisely, and can detonate a mine on or next to impact without ending the game.
Double-click any revealed number: if nearby flags match that number, adjacent cells auto-open.
Avia drones perform flyovers that erase opened intel and flags in a 5 x 5 or 6 x 6 zone and may reseed new mines in the inner area, while sea drones ambush when uncovered.
