Bry: You know I thought about Cylinder 5-in-line, along with some other games having cylinder versions - but for 5-in-line, since the board is some-what big already, I don't see a cylinder version being much different then the current game.

After looking at all the games offered here now, Cylinder Line 4 and Cylinder Froglet are the 2 which I personally think will be different enough from the original to make the games worth making.
