Go (game)
Two players, "Black" and "White", take turns placing a "stone" (game piece) of their own color on a vacant "point" (intersection) of the grid on a Go board. Black plays first. If there is a large difference in skill between the players, the weaker player typically uses Black and is allowed to place two or more stones on the board to compensate for the difference (see Go handicaps). The official grid comprises 19×19 lines, though the rules can be applied to any grid size. 13×13 and 9×9 boards are popular choices to teach beginners, or for playing quick games. Once placed, a stone may not be moved to a different point.
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.
