Help on a Snake and Ladder Game

Hey,
Guys am planning to make a snake and ladder game. But am running through a lot of problems already. Maybe i didn’t think it through.I am using tile method to place the board on stage.but am not able to figure out how make the player go to the desired location,which is decided by the number that is shown on the dice. especially since movement of the player is in zig-zap pattern(boustrophedon pattern). So can nebody help me out in anyway?

Thanks
