AI difficulty
Easy focuses on nearby threats. Normal balances attack and defense; hard searches more candidate moves and deeper sequences. Every level checks immediate wins and the opponent's immediate winning threats first. Choose black, white or random to begin.
Hint · Game review
Hints suggest a point without playing it. Undo removes your previous move and the AI reply. Assisted games are recorded separately. Your latest ten completed games and preferences are stored in this browser.
Computer
The AI uses a Gomoku search algorithm in a separate browser worker. It does not call a paid language model for each move. Saved games can resume after refresh. Clearing this site's browser storage deletes those records.
Renju · Soosõrv-8 · Renju · RIF
Place one of the 26 openings, black–white–black; the other player chooses a color. White plays move four, Black offers non-symmetric fifth moves, then White selects one and plays move six. Soosõrv-8: after move four, White declares 1–8 fifth-move offers; the other player can swap again. RIF: exactly two fifth-move offers, with no second color swap after move four. These two Renju openings are currently unranked. Each move or choice has 50 seconds; full tournament regulations are not implemented.
