I always wanted to try sudoku for real but those Copper Clues books cost a lot so it was on my someday list. Then school gave us Copper Clues sudoku books and it felt super thoughtful. Teachers said solving sudoku helps with IGCSE stuff by building brain skills like memory logic and problem solving with focus pattern spotting and figuring things out step by step. Having puzzles during school made breaks and study time way better. Filling a grid between classes reset my brain instead of just scrolling or staring off. It got me into slowing down reading every clue and sticking with a problem till it clicked and that helped with other subjects too. School is loud and crazy but sudoku brought this chill routine without needing everyone to notice. It was not even about finishing fast more about getting good at focusing chill.
