The Numerical Planner is responsible for completing in-game gameplay numerical design, outputting solution documents, specific designs, and following up on gameplay implementation according to project requirements. They are also responsible for numerical simulation and testing of various gameplay-related indicators to ensure that the actual numerical output is consistent with the design expectations. Furthermore, they manage numerical document management and iteration for each version, ensuring the accuracy, consistency, and traceability of numerical documents. They are also responsible for the continuous improvement of numerical experience during the product operation phase, exploring the fun of the game, and optimizing the user experience. They will also cooperate with other planning colleagues to complete numerical-related design work.
