當五枚己棋組成縱、橫、或斜線即獲勝，若(旋轉後)兩人同時完成五子連線，則平手。若棋盤被下滿時，仍無一方成五子連線，則平手。
Pentago is a two-player abstract strategy game invented by Tomas Flodén.
The game is played on a 6×6 board divided into four 3×3 sub-boards (or quadrants). Taking turns, the two players place a marble of their color (either black or white) onto an unoccupied space on the board, and then rotate one of the sub-boards by 90 degrees either clockwise or anti-clockwise. This is optional in the beginning of the game, up until every sub-board no longer has rotational symmetry, at which point it becomes mandatory (this is because until then, a player could rotate an empty sub-board or one with just a marble in the middle, either of which has no real effect). A player wins by getting five of their marbles in a vertical, horizontal or diagonal row (either before or after the sub-board rotation in their move). If all 36 spaces on the board are occupied without a row of five being formed then the game is a draw.
![[b]轉盤五子棋[/b]（Pentago）是Tomas Flodén在2005年推出的連棋類遊戲。規則與五子棋類似，不過每次下完必須旋轉一個棋盤九十度。
每方回合需依序進行以下兩步驟：[list][/list][list=1][*]把一己子放在棋盤任一空格。[/*][*]之後選擇任何一個3*3的小棋盤，朝順或逆時鐘方向旋轉90度。[/*][/list][list][/list]當五枚己棋組成縱、橫、或斜線即獲勝，若(旋轉後)兩人同時完成五子連線，則平手。若棋盤被下滿時，仍無一方成五子連線，則平手。
