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.

It features a knockout format culminating in a best-of-five final, with a champion's purse exceeding US$400,000. The tournament is famous for mandating its own special ruleset (Ing rules) and custom-designed equipment, including stone bowls that hold exactly 180 stones for a unique counting method. Champions include Cho Hun-hyun (1988), Lee Changho (2000), Chang Hao (2004), and Fan Tingyu (2012). In 2024, Ichiriki Ryo became the first Japanese player ever to claim the title, a landmark moment after decades of Korean and Chinese dominance.
