The popular game of Sudoku (a grid based number game) is fantastic for developing student's problem solving skills and persistence. It requires students to use a strategic and logical approach to figuring out which numbers (typically 0 - 9) fit in each box - so there are no numbers doubled up either horizontally or vertically.
There are many versions available (both online and paper) for children and adults alike. Below are some websites where students can play a variety of engaging Sudoku games - suitable for different age groups and abilities.
These types of puzzles are a fantastic resource to have available as a Maths warm up activity or as an extension/early finisher's challenge.
