Play Go against AI

Pick a level and start. Easy gives you room, Hard makes you count liberties honestly.

Black to play.

Sometimes you want to play Go without waiting for a person, opening a room, or drifting through a lobby before the first move even happens. That is what this page is for. It puts the three difficulty levels in plain view and lets you start immediately. Easy is forgiving enough for a warm-up, Medium feels like honest practice, and Hard is the setting that starts punishing the lazy one-liberty shapes you hoped nobody would notice. The AI replies right in the page, so the game stays quick and direct.

When to use this board

Use this page for a solo lunch break, a few clean capture drills, or a quick check on whether your reading is still awake. It is also the right page when you know you want a certain level of resistance instead of the homepage’s simpler default setup.

When not to

You are hunting a human lobby -> we do not host that. You want the person beside you instead -> 2 player. You have never learned liberties -> how to play. You only wanted a dedicated 9×9 page -> play 9×9.

How

  1. 01Pick Easy, Medium, or Hard on the strip above the board. The labels are there so you do not have to guess what mood the page is in.
  2. 02Tap an intersection and give the AI a beat to think. White is played here in the page, not in some remote browser tab somewhere else.
  3. 03If the game goes badly, start another one quickly. This page is built for repetition, not ceremony.

Gotchas

  • Hard is not a promise of professional strength. It is simply the strictest option on this site.
  • Closing the tab in the middle of a game can lose the position. There is no cloud match record to rescue it for you later.
  • A lot of “play against computer” pages are really installer bait or ad wrappers. This one is only the board and the AI.
  • Changing strength mid-game affects the next reply. The current position stays on the board.

FAQ

Is this for playing a real person online, or only for playing the AI?
Only the AI. This page is built as a direct sparring partner, not a human matchmaking room. If the other player is sitting next to you, open 2 player instead.
Is the engine running in the cloud, or on my own device?
On your own device. The AI runs in the page, so the experience feels more like “place a stone, wait a beat, get an answer” than “send the board away and hope a server sends it back.”
If I start a game and then realize the level is wrong, can I change it halfway through?
Yes. You do not need to throw the whole position away. Change the level and the current board stays; the new strength applies from the next AI move onward.
If the homepage already lets me play, why make a separate page for vs computer?
Because sometimes you are not browsing, you are training. This page makes the AI choice explicit and is easier to use for repeated starts, quick practice runs, and “I only came here to play AI” sessions.
