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 →The Meijin ("Master") carries more historical weight than any other Go title. During Japan's Edo period, "Meijin" was a singular honor bestowed on the one player acknowledged as the strongest of his generation -- legend has it the title originated when warlord Oda Nobunaga exclaimed "Meijin!" after witnessing a brilliant move by Honinbo Sansa in the late 1500s. The modern tournament was established in 1962, sponsored by the Asahi Shimbun, with a prize of 36 million yen. A nine-player round-robin league determines the challenger, who then faces the defending Meijin in a best-of-seven title match. Holding the Meijin remains the ultimate mark of prestige in Japanese Go.
