Tic Tac Toe vs JJ围棋

Think you know Tic Tac Toe? Think again. Twelve game modes, three AI difficulty levels, and a Survival mode that will push you to the limit — all offline, no account required. GAME MODES • Classic — The original 3×3. First to line up three wins. • 5×5 — A bigger board where four in a row takes the game. More room, more traps. • Order & Chaos — One player tries to make five in a row, the other tries to stop it. Either side can place X or O. • Infinite — Only 3 pieces on the board at a time. Your oldest disappears when you place a 4th. Every move could be your undoing. • Numerical — Forget X and O. Place numbers and be the first to reach a sum of 15. Strategy has never felt so different. • Pick 15 — Claim cells from a shared pool of digits. First to own three that add up to 15 wins. • 3D — Three dimensions, three layers, 49 ways to win. The deepest Tic Tac Toe you have ever played. • Misère — Same board, opposite rules. Get three in a row and you lose. Force your opponent into the line to win. • Wild — Place either X or O on every turn. The first to complete any three in a row wins. • SOS — Spell "SOS" on a 5×5 grid. Every word you complete scores a point and earns another turn. Highest score wins. • Quixo — Pick, flip, and slide cubes to push five of your symbol into a line. A modern classic. • Ultimate — A 3×3 grid of 3×3 boards. Your move decides where your opponent must play next. Think several steps ahead or fall behind.

Nineteen lines by nineteen—each stone, a world entire. Amid the din and dust of mortal life, seek out a tranquil board. Its three hundred sixty‑one crossings are the universe in miniature; its twin hues of black and white, the ceaseless interplay of yin and yang. Go is no mere contest of triumph or defeat—it is a discipline of the soul. A move made once and never regretted: that is the wisdom of relinquishment; the flowing stream that strives not to outrun its fellows: that is the serenity of accord with nature. Here, you may hold discourse with the sages of antiquity, and come to terms with the self you are today. Upon this modest wooden plane, you shall behold the very acme of Eastern beauty. Upon the grain of the board, we pursue the Way—and in stillness, we await your coming. 配乐：轻快的古风音乐 许可:CC-BY 作者:碎碎平安的碎碎 来源:耳聆网 https://www.ear0.com/sound/43878 Background Music: Lighthearted ancient-style Chinese music License: CC-BY Artist: 碎碎平安的碎碎 Source: 耳聆网 https://www.ear0.com/sound/43878
