About
Math meets logic in NumCages. Fill each row and column with every number once, then use the +, −, × and ÷ clues to solve each outlined cage.
HOW TO PLAY
In a 4×4 grid, place 1–4 once in every row and column. The number and symbol in each outlined cage give its target: “5+” means the two cells add to 5; “6×” means multiply to 6. A single-cell cage takes the shown number.
TRY THE FIRST MOVE
In the pictured 4×4, the top row already has 4 and 1. Its two blanks must be 2 and 3. Column 2 already contains 3, so put 2 in the top cell of that column and 3 to its left. Their “5+” cage adds up to 5.
Start with bite-sized 3×3 addition puzzles and work up to 9×9 grids with all four operations. Choose the grid size and calculation mix that fits your mood.
