Payment processing outage2025-12-22

Due to problems with our payment processing, new subscriptions of the last couple of days were not activated after the payment. The system works again and should process the missed ones, too. But in case you still don't get the new membership today, please reach out to [email protected].

Sorry for the inconvenience!

More Touch Input Customization2025-07-18

After the last update, we got a lot of feedback from users who prefer the old input method on touch screens. So we added options to customize the behavior more and changed the defaults back to how it was before.

On touch, there's also now a confirm dialog for important moves like when playing against an AI. There's a setting for this, too.

Game Record and Mobile Input Changes2025-07-16

We've made a couple of updates to improve the experience on touch devices and make editing game records more intuitive.

Input Changes for Touch Devices

EDIT: Offset and delay are now disabled by default, but you can enable them in the preferences.

Placing stones with your finger can be tricky, so we've added a few small improvements to help:

  • There's now a slight offset when placing a stone, so your finger doesn't block your view.
  • You'll see guide lines marking your current position.
  • After a short delay, the lines turn green to show the move is ready to be played.
  • The stone can only be placed once the cross is green.

This should help avoid accidental moves while keeping things fast and easy to use.

Game Record Improvements

We’ve also made it easier to fix mistakes in the game record:

  • You can now insert moves before existing ones.
  • You can drag misplaced moves to a new position.

If you run into any issues or have suggestions for further improvements, we’d love to hear from you.

In addition, we've invested in faster hardware and optimized our infrastructure, ensuring quicker real-time analysis.

Introducing: Learn Go!

We've just launched our brand-new Learn Go section—perfect for anyone new to Go or wanting to revisit the basics. This interactive beginner course clearly explains the rules and basic tactics, making it easy to share with friends who want to start playing.

New Humanlike Bots Across All Levels

Our humanlike bots used to be limited to 19x19 boards and stronger players, but we've now expanded their range significantly. You can now find bots that play in a natural, humanlike style from 30 kyu all the way up to 9 dan, and across all board sizes—19x19, 13x13, and 9x9. It's easier than ever to find a realistic opponent at your level.

Ranked 9x9 Mode Is Here
