Capture Go

Play:

Full screen Touch: Tap an intersection to place a stone there · Keyboard: Click an intersection with the mouse; R to restart, Esc to pause

About:

A clean implementation of Atari Go (first-capture variant) on a 9x9 board, with a genuine AI opponent, local Player vs Player, and an AI vs AI spectator mode. Tap-to-place stone accuracy was verified precisely: a specific target intersection was computed via the game's own coordinate math and confirmed to register exactly there via live board state, on both touch and mouse.

Credits:

Made by Atari Go: first capture wins, against a real AI, 2024. Published here under the MIT licence. Source code.

Phone check: 2026-09-07: played on simulated phone (390x844, real CDP touch dispatch) and desktop (mouse); computed exact screen coordinates for a specific target intersection via the game's own worldToScreen function and confirmed the stone landed exactly there via live board-array state, on both input methods.
