Super Brain: Sudoku

Super Brain: Sudoku is a puzzle app designed to train logical reasoning, candidate elimination, and focus. Players need to fill numbers into the grid so that every row, every column, and every box contains the full set of numbers without repetition. The app provides automatically generated levels that progress from easy to hard: easy uses a 4x4 beginner board, medium increases to a 6x6 transition board, and hard advances to the standard 9x9 Sudoku. The question bank first generates a complete valid solution, then removes numbers based on difficulty, ensuring that every puzzle has a corresponding answer. The answer screen focuses on progress, filled cells, conflict count, box state, candidate mode, and the number keypad, helping users build a solving rhythm of observing the board, recording candidates, filling unique answers, clearing conflicts, and finishing steadily.
