Choose a 15×15 or 19×19 board, your colour and the computer level, or play two players on one screen, with undo and last-move markers.
点击交叉点落子。黑方先下 1 颗，然后双方轮流每次下 2 颗；状态栏会提示本回合还能下几颗。Tap an intersection to place a stone. Black starts with one, then both sides take turns placing two; the status bar shows how many stones you have left this turn.
玩法说明与常见问题How to play & FAQ
「六子棋」怎么玩？How do I play Connect Six?
黑方先在棋盘上下 1 颗子，之后白方下 2 颗、黑方下 2 颗……如此轮流。任意一方在横、竖、斜任一方向上连成 6 颗（或更多）同色棋子即获胜。因为每回合能下两颗，对方的“活四”“活五”都必须马上堵住，同时你也可以一手两子形成双重威胁。Black places one stone first, then White places two, Black two, and so on. Whoever makes six (or more) of their stones in a row horizontally, vertically or diagonally wins. With two stones per turn, any open four or five must be blocked at once — and you can use your two stones to create a double threat.
为什么黑方第一手只能下一颗？Why does Black place only one stone at first?
这是六子棋的标准规则，用来平衡先手优势：第一手下一颗之后，双方每回合都下两颗，这样黑白两方在任何时候棋盘上的子数最多只差一颗。It is the standard rule that balances the first-move advantage: after Black's single opening stone both sides always place two, so neither ever has more than one extra stone on the board.
连成七颗算赢吗？Does a line of seven count?
算。只要同一条线上有连续 6 颗或更多自己的棋子就获胜。Yes — any unbroken line of six or more of your stones wins.
