What are the rules for moving your game pieces in the board game Trouble?

In the board game Trouble, players move their game pieces by pressing the pop-o-matic bubble to roll the dice. The number rolled determines how many spaces the player can move their piece forward on the board. Players must move their pieces clockwise around the board and must move the full number rolled unless they land on a space occupied by another player, in which case they must "bump" that player back to the start. The first player to move all their pieces around the board and into the finish zone wins the game.
