Will you try to advance by furious attacks or step back with strong defense? Your goal in this game is to use at least 5 of your pieces to form an unbroken line in horizontal, vertical or diagonal direction. When the game starts, you will be given a board with 19x19 intersections. You and your opponent will be using black and white pieces respectively, and black always moves first. During your turn, you can click to place a piece onto an empty intersection on the board. Note that you must finish your move within the given time limit, as indicated by the timer on the left of the screen, or you will lose. After you have placed a piece, your opponent will take his turn and the game continues. When a player can form a horizontal, vertical or diagonal line with at least 5 of his pieces, the game is won. Observe carefully and beware of the tricky moves of your opponent!
