Hi, welcome to FMH
This looks pretty similar to this post

You'd get a quicker response if you post some background, and show what you've tried yourself to solve the problem. Are you a student doing this for fun? If so then what level of mathematics do you know? Is this a board game or a computer game? Do you want to solve the problem yourself, with some help, or are you just after a straight final answer (this site is more aimed at helping people to solve their problems rather than just giving answers, but exceptions do happen to this if the poster can provide some relevant info)
