Sudoku trains two skills at once. Pattern intuition: you see where a number goes before you’ve worked it out. Calculation: you eliminate candidates row by row, column by column, until a cell is forced.
Most sudoku apps give you all the time in the world, so you only train the slow side. Battle royale puts a clock on it. Faster solver takes the cell and the points. Switching between fast and slow under pressure builds working memory and decision speed — useful well beyond the board.
