I learned the basics of Connect 6 by using a triangular grid, and then graduated to the standard Go board when I started playing on LG. Because of this, I have a soft spot in my heart for using a hexagon board, even though the game becomes difficult because defenses are so strong (there are no diagonals, therefore a single move can form an unbreakable wall).
I've found an interesting way to fix this, however: On a triangular grid, using the same rules as Connect 6, except that your goal is to either get 6 in a row OR a ring of six (doesn't matter what's inside). The game can go fast, and it's something worth looking into I think.
