Object of the Game
Black must form an orthogonally (horizontally and/or vertically) interconnected path of black stones connecting the two black edges of the board. White must connect the two white edges.
Play
The two players, Black and White, take turns placing their own stones onto unoccupied points, one stone per turn, starting with Black. Passing is not allowed, but if you don't have an available placement, your turn is skipped. Minefield uses the pie rule. White, on his first turn, has the option of switching colors and becoming Black, claiming the first placement as his own, instead of placing a white stone.
Players are not allowed to form any prohibited glyphs (patterns), explained in detail below.
Hard Corner
A "hard corner" is comprised of two stones of one color and one stone of the other color contained in a 2x2 area. The two same-colored stones are diagonally adjacent. One point within the area is unoccupied.
Switch
A "switch" is comprised of two stones of each color contained in a 2x3 or 2x4 area. Two stones of one color occupy diagonally opposite corner points. The two stones of the other color occupy the other two diagonally opposite corner points. The non-corner points are unoccupied.
Players are not allowed to form any hard corners or switches, including their reflections, rotations, or color reversals.
Example
All illegal placements for a player would form hard corners, short switches, or long switches. All other unoccupied points are legal placements.
Design Notes
Luis Bolaños Mures made a material contribution to Minefield. Minefield is an SPO OOSCG (Single Placement Only, Orthogonal Only Square Connection Game).
