Gomoku Blog

Strategy tips, game comparisons, and in-depth guides to help you master gomoku (five in a row).

Choose a reading path

If you are new to the game, begin with how to play and the rule comparison. Those pages define the exact-five house rule used by our browser board and show where formal Renju differs. After one or two games, the first-move section of the openings guide explains why the center is a useful default without claiming it is always optimal.

If you already know the rules, use the strategy learning path alongside the opening articles. The practical opening article offers decisions to test in casual play; the separate Renju opening guide shows six named first-three-stone positions. Check which rule set an example uses before transferring a tactic to another app.

If you learn best from complete games, the two game reviews replay full 9x9 games move by move — a double-three fork and a won-by-move-order finish. Every threat count quoted in them is computed by the site's engine and asserted by a test, and the practice page turns the same patterns into exercises.

If you came with a specific question, the comparison and research articles may be faster than reading the whole list. The solved-game article separates a published result for a defined Gomoku setting from claims about every variant. The AI programming guide provides code you can run and modify. The iPhone article compares four ways to start a game with a friend or practice alone, rather than ranking changing app-store listings.
