The appraisal value changed depending on the appraisal team that appeared after battle. When the dig (掘る?) command was selected, an action gauge next to the player character's icon would decrease.

For each turn, players had to spin the roulette, and the character would advance automatically along the board by the number spun.

Some squares triggered battles, and others granted players treasure. Players could also find members of the Straw Hat Pirates on the squares. Passing through the squares they were on would cause them to help players in their next battle.
