Two bowls or lids to hold stones and captured prisoners; Pass stones — under AGA rules a player who passes hands the opponent a stone, which counts as a prisoner (AGA Rule 7); A game clock for timed and tournament play
Why people argue about this
People often assume that the bowls or lids mentioned in the rule are decorative items used for aesthetic purposes rather than functional ones needed to hold stones and captured prisoners during gameplay. The confusion arises because these containers are crucial for managing game pieces, especially in timed matches where keeping track of each stone's position is essential.
