One step leads to the next
Find its last liberty.
A course that starts with your first stone and builds towards independent play. Every lesson opens the door to the next idea, with time to revisit what you have learned.
Start from zero. Or build on what you know.
The white move fills the black stone’s last liberty. With no liberties left, the black stone is captured.
Concept exercise. Open the explanation to explore the move.
Place a stone, try a connection, save a group. A short explanation gives you what you need, just when you need it. Then the board gives the idea meaning.
A missed connection becomes something to work on. After an AI learning game in Learn or Practice, turn key mistakes into personal exercises — and try the idea again in a fresh position.
Put an idea to work against on-device AI.
See the situation behind a learning mistake.
Return to it in a focused exercise.
Personal exercises follow AI learning games in Learn and Practice. Free Play is a separate space for a game of your own.
