we will talk about the more advanced mathematics behind various children's games including the algebraic properties of liar (a.k.a. ``b.s."), the probabilistic applications toward chutes and ladders, and the algorithm dynamics behind guess who?. hopefully, after this talk, you will be able to beat your little brother or sister at their favorite game(s). if you have any games that you would like to be discussed, you also may provide me with your suggestions.
