Cage Grid
Fill every row and column with each number once. The thick-outlined cages show a target and an operation: the numbers inside have to make it.
How to play
- Put the numbers 1 to 4 in every row and every column — no repeats.
- The bold outlines are cages. The numbers inside a cage must make the cage's target using its operation (+ −).
- Tap a square, then tap a number. Turn on Notes to jot down possibilities.
