OneSolve Gomoku

Play against an opponent that actually calculates the kill.

■ Ten stages, one at a time
A stage isn't a dan number, it's a playing style. "Novice" only looks one move ahead. "Steady" starts building double threes. "Strong" reads eight-move combinations. You'll know exactly which kind of opponent you get stuck on.

■ On-device engine, no internet
The search runs on your phone. No server, no account, works in airplane mode.

■ Games save themselves, review any time
Every finished game lands in your library. Step through it move by move and see what the engine thinks of each one. You can also import someone else's SGF file or plain move list.

■ Play a friend on the same Wi-Fi
No sign-up, no server in the middle — the two devices talk directly.

■ AI Coach (sold separately)
While you play in some other Gomoku app, this one tells you where to move. It reads the board off your screen and answers by voice and in a floating window.
It talks the way a person would — "add to the right end of your row of three" — not grid coordinates. Nobody can count sixteen lines mid-game.
Recognition and search both run on your device. Nothing about your screen leaves the phone.
Free for 24 hours, then a one-time purchase, yours for life. Not a subscription.
