Quad

Quad is played on an empty 8x8 square board.
There are 12 to 25 stones of each color off-board(the exact number should be decided by the players).
At each turn,each player must do one of the following things:
1.Drop a friendly stone into an empty cell.
2.Move a friendly stone to an orthogonally empty cell.
There are custodian captures(if the moving stone goes to a cell where an adjacent enemy stone is sided by it and another friendly stone,then the enemy stone is captured).
Wins the player that (a) makes an orthogonal 4 in-a-row,(b) stalemates the adversary or (c) captures all enemy stones.
