When main time expires, byoyomi begins. The game ends when all configured byoyomi periods are exhausted.
After main time expires, players must make a specified number of moves within a specified time (e.g., 10 moves in 5 minutes). Failure to complete the moves in time results in a loss.
Players move with byoyomi timing, entering thinking time when byoyomi expires. The game ends when the last thinking time is used or when byoyomi expires with zero thinking periods remaining.
A specified amount of time (e.g., 5 seconds) is added after each move. The game ends when time runs out.
