AI Sensei

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.

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.

We're thrilled to announce a major update to AI Sensei packed with improvements and exciting new features designed to boost your Go learning and playing experience.
