Gomoku Coach

Playing is free forever, no ads. When the game ends, Review finds the losing move; Coach Pass (one purchase) explains every move after it.

Gomoku that tells you why you lost.

Most gomoku apps stop at "you lost." Kukmin Omok goes one step further. When a game ends, tap Review. Every move you played is re-searched at full strength to find the exact move that decided the game — then the engine plays out what happened next, one move at a time, and explains each one.

"Move 12, K10 — four-three. It forces you to block the four, then grows the open three into an open four." "Move 13, J9 — forced block. There is nowhere else to play."

You stop memorising moves and start understanding reasons.
