Definitions

Group: Either a single stone (a group of one) or any number of stones of the same color connected through a continuous series of orthogonal adjacencies.

Play

First player places a single black stone on any grid intersection, after which the second player decides which color they will play (pie rule). Players then alternate taking turns.

On your turn, place a stone of your color on an empty point. Then, if possible, place a stone of your color on an empty point that is orthogonally adjacent to two groups of your color, and keep making such placements until no more are possible.

Acknowledgments

Every one of the regular posters on the BoardGames Abstract Game forum could rightfully consider themselves a co-author of this game if they wished. I'm like a kid who built something (hopefully cool!) out of LEGO -- but they made the bricks. Thank you all for your generosity and brilliance.

Luis Bolaños Mures helped clarify the presentation of the rules - Thanks.

This game shares some similarities with Quadrex by Bill Taylor, although it was arrived at independently.
