====== Four In A Row ======

Get four or more in a line on a square grid with **gravity**: stones fall down a column until they rest.

Inventors: Ned Strongin, Howard Wexler

===== Rules =====

Related commercial game: [[https://boardgamegeek.com/boardgame/2719/connect-four|BoardGameGeek: Connect Four]]. Overlines count as wins (four **or more**).


===== Variants =====

==== 10×10 board ====

Larger grid (''standard-10'').

==== Swap-1st / Swap-2 / Swap-5 openings ====

Pie-style colour swaps after the first stone, after a three-stone offer, or after each of the first five stones.

==== Edge-grow-4 ====

You may also grow inward from the other three edges: place in the first empty cell from top, left, or right, not only from the bottom.

==== Interior-gravity-4 ====

You may click any empty cell; the stone then slides toward the nearest edge (or along the diagonal toward a corner when equidistant) until it sits against a stone or the rim.

==== Clear ====

If an entire edge row or column is full, it is cleared and remaining stones shift that way — **unless** a four-in-a-row already exists, which wins first. With four-edge placement, any full edge line can clear.
