One app support multiple variants of board game:

+ Tic Tac Toe: Tic-tac-toe (American English), noughts and crosses (Commonwealth English), or Xs and Os (Canadian or Irish English) is a paper-and-pencil game for two players who take turns marking the spaces in a three-by-three grid with X or O. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row is the winner

+ Gomoku: also called Five in a Row, is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a 15×15 Go board while in the past a 19×19 board was standard. Because pieces are typically not moved or removed from the board, gomoku may also be played as a paper-and-pencil game (X and O). Players alternate turns placing a stone of their color on an empty intersection. Black (X) plays first. The winner is the first player to form an unbroken line of five stones of their color horizontally, vertically, or diagonally

+ Caro: In Caro, (also called gomoku+, Co Caro, popular among Vietnamese), the winner must have an overline or an unbroken row of five stones that is not blocked at either end (overlines are immune to this rule). This makes the game more balanced and provides more power for White to defend.
