Logic games
Logic games, abbreviated LG, and officially referred to as analytical reasoning, is one of three types of sections that appear on the Law School Admission Test (LSAT). A logic games section contains four 5-8 question "games," totaling 22-25 questions. Each game contains a scenario and a set of rules that govern the scenario, followed by questions that test the test-taker's ability to understand and apply the rules, to draw inferences based on them. In the words of the Law School Admission Council (LSAC), which administers the test, it "measure[s] the ability to understand a  structure of relationships and to draw logical conclusions about that structure." Like all other sections on the LSAT, the time allowed for this section is 35 minutes. While most students find this section to be the most difficult section on the LSAT, it is widely considered the easiest and fastest to improve at once the right strategies are learned and employed. Common game types. Basic linear. In a basic linear game, two sets of variables are provided. The first set of variables, sometimes referred to as the 'base variables,' is often days of the week, an order of arrival, or  some other order. The second variable set is then matched to the first set according to a set of rule. For example: After setting the scenario, the game challenges the test-taker with questions such as: Advanced linear. Advanced linear games are similar to basic linear games, but three or more sets of variables are presented. For example: The game can then provide rules and pose questions relating to the order of arrival of a runner, the color of a specific runner's shirt, sequences of color that must or must not be present, the shirt color of the runner  that comes first etc. Grouping. Grouping games provide variables that must be assigned to groups, but not in a specific order or sequence. For example: Grouping linear combinations. Combination games follow a similar structure but include both linear and grouping elements. Less common game types. In addition to the common games, the LSAT sometimes includes other types of games that appear less frequently. Examples of less common games are: Method. To solve the game quickly and efficiently, test-takers usually draw a master diagram at the bottom of the page. The rules and key inferences are written down in short  symbols next to the diagram, and, where possible, marked on the diagram itself. A smaller diagram can also be drawn next to a specific question if that question poses any additional rules. On some games, it is helpful to create separate diagrams of all the possibilities and then use that to tackle the questions.
