The implementation of Pente here has added some new (as far as I know) online playing options and combinations to online Pente play. Specifically, the self capture forbidden option is one which I haven't seen implemented anywhere else and the self capture enabled game as implemented here counts a 10-10 capture score as a drawn game (as opposed to an overtime scenario).
Potential for expansion of the options for Pente would be the following:
1. 13x13 board (sometimes referred to as small Pente)
2. exactly five in a row needed to win (two options here - overlines forbidden and overlines just don't win)
3. making two open threes or two open fours with a move is forbidden (either for the first player or both players)
Combining some version of 2 and 3 with the current overtime capture allowed rule enabled is an implementation of Pente's parent game ninuki renju.
