Gomoku AI - Five in a Row

Most Gomoku apps are easy to beat. This one is not.

Under the hood is a tournament-grade engine. At full strength it searches millions of positions per move and plays beyond human world-champion level. At lower levels it makes the kind of honest, human mistakes a club player would - so every rank on the ladder feels like a real opponent, not a dice roll.

And it all runs on your phone. No servers, no account, no connection - the engine thinks locally, even in airplane mode.

FIVE RIVALS, ONE LADDER
Work your way up from Novice to Grandmaster against five hand-drawn characters, each with their own playing strength. A hint button lets you peek at the engine's own choice when you're stuck, and you can undo and swap sides freely while you learn.

A WORLD TOURNAMENT CIRCUIT
Join open tournaments from Hanoi to São Paulo. Nine-round events, real tournament rules (Renju, Swap2), Fischer clocks with byo-yomi, and an Elo rating that decides your rank - climb from league D to the world crown.

PUZZLES THAT TEACH
A trail of handcrafted win-in-N puzzles, verified by the engine so every solution is sound and every defense is the opponent's best. Three chapters, star ratings, and an interactive tutorial that teaches openings, shapes, and the forbidden-move rules of Renju from zero.

EVERY SERIOUS RULE SET
Freestyle, Standard (overlines don't win), Renju with forbidden moves, and the Swap1/Swap2 opening protocols used in real competition. Play the rules your region plays.

FIVE MORE GAMES INSIDE
When you need a break from five in a row: Othello, Checkers, Nine Men's Morris, Fank (the Vietnamese folk game of flanking), and Suika Stones, a physics merge game - all against the same adaptive AI, all offline.

MADE LIKE AN OBJECT, NOT AN APP
Stones with weight, boards with paper grain, and a collection of hand-painted sumi-e ink-wash sceneries to unlock with the stars you earn by winning. Match history, trophies, and a rankings ladder track the whole journey.

ALSO WORTH KNOWING
• Works completely offline - nothing to sign up for, nothing tracked across the internet
• Available in 14 languages
• Phone and tablet layouts
• Board coordinates, last-move marker, and win-line display for study

Whether you call it Gomoku, Omok, Gobang, or Five in a Row - if you want an opponent that respects your intelligence, it's waiting.
