How to play Sum Pockets

Fill the grid so every row, every column and every block uses each number once. Dashed lines make pockets. The numbers in a pocket add up to the number in its corner, and a pocket never uses a number twice.

Sum Pockets is our own Killer Sudoku for kids, also called sum sudoku. In Killer Sudoku the pockets are called cages. It starts with pairs on a 4 by 4 grid, so it is great number bond practice, then grows to 6 by 6 and 9 by 9. Like puzzles? Try Box Clever, Sign Hop or our maths games.
