the rules are simple! to preface, you always play the white stones; the computer always plays the black stones. to move a stone, click and drag.

players may freely move their stones up and down their respective columns. the only two restrictions are as follows:

(1) on both players' first moves, they may not "cross the river". that is to say, on black's first move, they may not move their selected stone across the river; on white's first move, they may not move their selected stone across the river.

(2) stones may not hop over each other.

that's it! this is a game of "don't die first": it is game over if you have no more moves to make. hypothetically, a game could last forever if players are evenly matched. see if you can beat the computer :)
