Most Gomoku apps are easy to beat. This one is not. A tournament-grade engine, five rivals, world events, puzzles - and five more classic board games, all running entirely on your device.

Gomoku AI gameplay against the Monk rival on a 15×15 paper-grain board

A look inside

Made like an object, not an app

Stones with weight, boards with paper grain, and hand-painted ink-wash sceneries to unlock with the stars you earn by winning.

A champion-grade engine

At full strength the engine searches millions of positions per move and plays beyond human world-champion level - entirely on your phone, even in airplane mode.

Five rivals, one ladder

Climb from Novice to Grandmaster against five hand-drawn characters. Lower levels make honest, human mistakes, so every rank feels like a real opponent - not a dice roll.

A world tournament circuit

Nine-round open events from Hanoi to São Paulo with real tournament rules, Fischer clocks with byo-yomi, and an Elo rating that decides your rank.

Puzzles that teach

Handcrafted win-in-N puzzles verified by the engine, three chapters with star ratings, and an interactive tutorial covering openings, shapes, and Renju’s forbidden moves.

Every serious rule set

Freestyle, Standard, Renju with forbidden moves, and the Swap1/Swap2 opening protocols used in real competition. Play the rules your region plays.

Five more games inside

Othello, Checkers, Nine Men’s Morris, Cờ Gánh, and Suika Stones - all against the same adaptive AI, all offline.
