Twirls of Action is played on a 9x9 or 8x8 Go board.
The game has same starting set up as the Classic Lines of Action, and the end goal is almost the same as well.
A player wins when they connects all of their stones, where each stone does not have more than three adjacent (diagonal or orthogonal) friendly stones.
From The World of Abstract Games:
MOVE - Each stone move by a Twirl movement. This is done on the following steps:
Select an enemy stone as the Pivot (at a distance of N cells);
The Pivot must be on a straight line (diagonal or orthogonal) without any other stone in-between;
The stone can go another empty cell at the distance of N cells from the Pivot;
The origin and the destiny cell must be on a straight line (diagonal or orthogonal) without any other stone in-between;
