How to Start Playing Go on a Small Board
Heshan Fernando
Co-founder & COO
Go has two rules that fit in a paragraph and a reputation for being impossibly deep. Both are true, and the standard mistake beginners make is starting on a 19×19 board, where a game takes an hour and nothing that happens is comprehensible.
Start on 9×9. Games take five minutes, fights resolve immediately, and the two concepts that matter become obvious.
The rules
Players alternate placing stones on the intersections of a grid. Black first.
A group of connected stones lives while it has at least one liberty — an adjacent empty intersection. Remove the last liberty and the whole group is captured and taken off the board.
That’s essentially it. The only additions are that you can’t play a move that recreates the previous board position (the ko rule, preventing infinite loops), and you can’t play a stone with no liberties unless doing so captures something.
The goal is to control more territory than your opponent — empty intersections your stones surround.
Why 9×9 first
On a small board, a single fight often decides the game, so cause and effect are visible. You place a stone, you see the consequence, and the ideas of liberties, connection and cutting become intuitive within a few games.
On 19×19 the same concepts apply across four or five simultaneous local games, and a beginner can’t tell which move lost the game because the answer was forty moves earlier in a different corner.
Move up when 9×9 feels small — usually after twenty or thirty games. 13×13 is a genuinely good intermediate step that gets skipped too often.
Scoring, and why there are two systems
Japanese scoring counts your territory plus the opponent’s stones you captured.
Chinese scoring counts your territory plus your own stones on the board.
They usually agree within a point, but they reward the endgame differently: under Chinese rules, filling in your own neutral points costs nothing, while under Japanese rules it costs you a point of territory. That changes optimal endgame play slightly.
Komi is the compensation given to White for moving second — typically 6.5 points. The half point exists so that draws are impossible.
| System | Counts | Endgame Effect |
|---|---|---|
| Japanese | Territory + captures | Filling own territory costs a point |
| Chinese | Territory + own stones | Filling own territory is free |
| Komi | 6.5 to White | Half point prevents draws |
Why people get stuck here
- Starting on 19×19. The single biggest barrier for beginners.
- Trying to capture everything. Territory wins games; captures are a means, not the goal.
- Not understanding when a group is dead. A group that can’t make two separate eyes cannot live, and recognising that saves enormous wasted effort.
- Playing on the first line early. It looks like territory and gains almost nothing.
Common mistakes to avoid
- Chasing captures while your opponent quietly takes the whole board’s territory.
- Playing every move next to your last one, which builds a dense, inefficient shape.
- Filling in your own eyes, which kills your own group.
- Adding stones to a group that’s already unconditionally alive.
- Counting territory only at the end rather than estimating throughout.
How to do it with Go Board
The Go Board gives you a board for two players or for working through a position, with captures handled automatically.
- Choose 9×9 to learn, 13×13 to progress, 19×19 for a full game.
- Play alternately; groups with no liberties are removed for you.
- Count at the end under your chosen ruleset.
- Use study mode to replay a position and try a different move.

Frequently asked questions
Which board size should a beginner use?
9×9. A full game takes minutes, fights resolve quickly, and liberties and capture become clear far faster than on a full board.
What’s the difference between Japanese and Chinese scoring?
Japanese counts territory plus prisoners; Chinese counts stones plus territory. They usually agree within a point but reward endgame filling differently.
Why is there a half-point komi?
To prevent draws. Adding 6.5 rather than 6 to White’s score guarantees one side wins outright.
Final thought
Play twenty games on 9×9 before touching a bigger board. The concepts don’t change with board size, but on a small board you can actually see them working.
