+# Corporate Conundrum: Decisions in Disguise
+
+This is the web version of a board game, coded entirely in SQL.
+
+## Pitch
+Unleash your inner executive as you step into the shoes of top-level employees in a high-stakes corporate meeting. But beware, among your trusted colleagues lurks a cunning infiltrator sent by a rival company to sabotage your decision-making process. Will you be able to outsmart the saboteur and make the right choices to lead your company to success?
+
+## Rules
+
+**Objective**: As a team of genuine employees, your goal is to make accurate decisions based on challenging questions. The infiltrator's objective is to sway you toward incorrect answers.
+
+**Gameplay**: Each turn, a question will be presented to the group. One player, secretly assigned as the infiltrator, will receive a specific wrong answer. They must cunningly lead others astray, while you must collaborate and deduce the correct answer.
+
+**Discussion Phase**: Engage in lively debates and exchange ideas to uncover the truth. Analyze arguments, question motives, and use your critical thinking skills to navigate the murky waters of corporate deception.
+
+**Hidden Votes**: After the discussion phase, all players simultaneously submit their individual answers privately, without revealing them to others.
+
+**Scoring System**: Points are awarded based on the proximity of each player's answer to the true answer.
+
+ - If a player's answer is closer to the true answer than to the wrong answer provided by the saboteur, they earn one point.
+ - Conversely, if a player's answer is closer to the wrong answer, they inadvertently contribute one point to the saboteur's score.
+
+**Continuing Gameplay**: The game progresses with new questions and role assignments, allowing each player to take turns as the infiltrator. The player with the highest score at the end of the predetermined number of rounds wins the game.
+
+
+## Web app usage
+
+Create a new game by clicking the "New Game" button. You will be prompted to add new players to the game by adding their names. Share the game URL with other players so they can join the game.
+
+Role Assignment: The web app will randomly assign roles to players, designating one as the infiltrator.
+
+Question and Wrong Answer: The web app will display the question to all players, and only the infiltrator will see an additional mention with the assigned wrong answer.
+
+Discussion and Decision-making: You need to be in the same room as the other players, and discuss the question and the wrong answer. The infiltrator will try to convince you to choose the wrong answer.
+
+Answer Submission: Once the discussion phase ends, enter your individual answer into the web app. The web app will track points earned based on the accuracy of each player's answer.
+
+Get ready to immerse yourself in the thrilling world of corporate espionage, where every decision is shrouded in uncertainty. Can you decipher the truth from deceit and lead your company to victory? Prepare for "Corporate Conundrum: Decisions in Disguise" and prove your mettle as a strategic mastermind!
