Below are the bracket from two of the preliminary tournaments.
The first time control for main tournament games was ten minutes per player. Once this was used up, a second time control of 10 one-minute periods of began. Each player was given 30 seconds to make their move. If they did so, then no thinking time periods were used. If, however, they did not, a thinking time period began and they then had up to one minute (more specifically 59 seconds) to make a move before entering the next thinking time period. This process was repeated until a player had used all ten thinking time periods. Then, the final byōyomi time control of 30 seconds per move then began.[3] Sente was determined prior to each game by piece toss.
