The game is not really "tic-tac-toe"; the basic rules are:
* alternating play on an unbounded hexagonal grid (within the hexagons, not at intersections)
* X places the first move (but since the grid is unbounded, there is not really any choice in the position); then players alternate placing two marks
* six marks in a row are required to win
The first video above basically covers the development of this ruleset (and motivates rejection of alternatives). The result has, apparently, proven surprisingly interesting, with a community rapidly emerging around the game.
This implementation follows exploratory design of the game and research into strategy in a series of YouTube videos:
