Gomoku
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 Go board, using 15×15 of the 19×19 grid intersections. Because pieces are not moved or removed from the board, Gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names.
Mojo (board game)
"Mojo" is played with 3 pieces each and a single neutral pawn, used as a blocker, that is common to and may be moved by both players. The game starts with the pawn in the center of the board and during play, there is a choice of 2 empty spaces. Players take turns placing their 3 pieces on the board, one at a time, on any empty position, building on those already on the board, to complete and/or block winning rows. Then, continue by moving any piece (including the opponent's) or the pawn to an adjacent empty space. Players may move the pawn. Pieces and pawns may not jump over each other and the last piece or pawn moved may not be returned to its previous position. The game is over when a player has 3 same-color pieces in a row - horizontally, vertically or diagonally and is then the winner of the game.
