Victory in PvP depends on the selected mode. In Rapid, only one pawn needs to reach the center, while in Classic and Mini, all four pawns must reach the center to win. The catch is that you must roll the exact number needed to enter the final space. For example, if your pawn is two steps away, only a roll of two will let you finish.
This rule makes endgames highly dramatic. Even if you are leading, an unlucky streak of rolls can delay your win, giving opponents time to catch up and turn the tables.
