Math Grid

A cage-arithmetic number puzzle: fill the grid so every row and column holds 1 to N once, and each outlined cage hits its target. Four sizes, two difficulties and a daily puzzle; every grid has exactly one solution. Logic

How to play

1. Fill the grid with the numbers 1 to N so no row or column repeats a number.
2. Each outlined cage shows a target and an operation (+, −, ×, ÷): the numbers inside must combine to that target. Subtraction and division ignore order.
3. Use Notes for pencil marks. Undo is unlimited; the first three hints are free.

Controls

• Touch: tap a cell, then the number pad
• Keyboard: digits to place, arrows to move, Backspace/Delete to erase, N toggles notes, Z undoes
