Start on setting 6, capture white stones in the black-first three-move life-and-death puzzles, and build your stock. Promotion leads through 5-, 7- and 9-line boards. Beat the CPU match challenge after the 9-line stage to unlock Giant Group Rush; completing that section clears the game.
Play and controls
Open the official free browser game. Choose a setting at the title screen. Click or tap an intersection to place black. Use 決着 (resolve) and 勝負手 (decisive move) when shown. The CPU match also offers パス (pass), 終局 (end) or 投了 (resign) as appropriate.
| Stage | Rule |
|---|---|
| Black-first three-move puzzle | Add captured white stones to stock |
| Every black move | Spend one stone |
| Promotion | 5→7→9 lines |
| CPU match | Win to unlock Giant Group Rush |
| Final rush | Use the decisive-move prompt and finish |
First-run walkthrough
- Choose setting 6. Its CPU match uses the smaller 5-line board.
- Inspect the white group's liberties. Empty adjacent intersections are escape routes; closing them enables capture in Go. This is general strategy, not a verified move list.
- Capture to replenish stock. Random black placements cost stones without helping.
- Re-read each new board after promotion. Earlier coordinates do not transfer to a different position.
- Practise the CPU match and win. The developer explicitly allows repeated practice even with insufficient stock.
Settings, score and FAQ
| Setting | Difficulty | CPU board |
|---|---|---|
| 6, 5 | Easier | 5 lines |
| 4, 3 | Medium | 7 lines |
| 2, 1 | Harder | 9 lines |
Harder settings have higher score multipliers. The score's last digit encodes the setting in reverse: 6 means setting 1, 5 means 2, 4 means 3, 3 means 4, 2 means 5, and 1 means 6. Winning the match unlocks the next board setting. Rankings cover score and cumulative captured points.
What are two eyes? Two separate internal spaces that keep a Go group alive; the game includes two-eye exercises and markers. Is there a universal three-move solution? No, every board needs its own reading. Exact puzzle solutions and final moves have not been verified hands-on. Learn the puzzle–stock–match–rush loop before chasing multipliers.
