六子棋 (Connect6)

a) 規則簡單：除了黑的第一手下一子外，黑白雙方輪流各下兩子。最後，連成六子者勝（類似五子棋）。
b) 變化複雜：由於一次下兩子，組合非常多，可說是千變萬化。複雜度已被評估為僅次於圍棋及日本將棋，遠高於五子棋及西洋棋，與象棋相當或略高。
c) 遊戲公平：由於各方每次下完一手後，盤面都比對方多一子，因此賽局可自然達成平衡的狀態，這使得公平性大為提升。不若許多棋種如五子棋、象棋、西洋棋，先下具有一些優勢。 a) rules are simple: In addition to first-hand the next sub-black exterior, black and white sides take turns each child under two. Finally, even into six sub-wins (similar to backgammon).
b) changes in the complex: As a child under two, the combination of a lot can be said to be changing. Complexity has been assessed as second only to Japan's Go and chess, backgammon and chess is much higher than with the chess equivalent or slightly higher.
c) Fair Game: Due to the parties under each hand and finished after more than a disk other than the child, so naturally innings to reach a balanced state, which makes equity greatly improved. Not as many species, such as chess backgammon, chess, checkers, first under some advantages.
