Network games of incomplete information represent strategic network formation when agents do not know in advance their neighbors, i.e. the network structure and the value stemming from forming links with neighboring agents. In such a setting, agents have prior beliefs about the value of attaching to their neighbors; take their action based on their prior belief and update their belief based on the history of the game. While games with a fully known network structure are widely applicable, there are many applications when players act without fully knowing with whom they interact or what their neighbors’ action will be. For example, people choosing major in college can be formalized as a network game with imperfect information: they might know something about the number of people taking that major and might infer something about the job market for different majors, but they don’t know with whom they will have to interact, thus they do not know the structure of the network. (Wikipedia).
18. Imperfect information: information sets and sub-game perfection
Game Theory (ECON 159) We consider games that have both simultaneous and sequential components, combining ideas from before and after the midterm. We represent what a player does not know within a game using an information set: a collection of nodes among which the player cannot distingui

By Their Powers Combined: Sudoku and LSAT // Logic Games [#20] [LSAT Analytical Reasoning]
When I teach LSAT games, one of the ways I introduce them is that they are like sudoku puzzles if you had to build your own grid every time and didn't have enough information to solve the puzzle. So I was pretty delighted when I worked the closest-to-actual-sudoku LSAT game I've ever seen.

Basic Approach, Pacing, and Order Games // Logic Games [#01] [LSAT Analytical Reasoning]

Grouping Games: More Spaces Than Elements // Logic Games [#02] [LSAT Analytical Reasoning]
The first game we tackled was a pretty basic one-to-one order game (which you can see here: https://youtu.be/LjrkGN4oN5U). Unfortunately, not all games have the same number of elements as spaces. In this case, the second game from the June 1991 LSAT is a grouping game in which we re-use th
