Each tile is a move you could play next. Tap one to play it: it lands on the board as a numbered stone, and this panel refills with the options that follow. Keep tapping to build a line.
- The Variation panel above lists the moves you've played. Tap any of them to rewind there; tap ← Main line to return to the game.
- Tap Preview on the current move to lay the whole continuation on the board at once — the AI's best line, or the recorded one if the game has it. Tap again to clear.
- Tiles tagged sgf are variations saved in the game record.
- Each tile's corner shows how good the move is — from blue (best) through green and yellow to red — the same color it has on the board. The blue-highlighted tile is the AI's top choice.
- The move actually played in the game isn't shown here — only the alternatives.
New lines you play here are read to 100 visits — quick, but shallow. A deeper read finds longer, stronger continuations.
See deeper analysis plans →Established in 1962 by the Sankei Shimbun newspaper, the Judan ("Tenth Dan") is the fourth-oldest of Japan's seven major titles, with a winner's prize of approximately 14 million yen. Its name evokes the pinnacle of Go rank -- historically, 9-dan was the highest official grade, so "Tenth Dan" symbolically places the champion beyond even that ceiling. The Judan stands out for its unusual double-elimination preliminary format: a player who loses in the winners' bracket drops to a losers' bracket rather than being eliminated, and the two bracket winners face off to determine who challenges the defending champion in a best-of-five title match.
