How to Play

• Fill the grid so every row and every column contains each number exactly once (1–4 for a 4×4 grid, 1–6 for a 6×6 grid).
• Heavy-outlined regions are cages. Numbers in a cage must combine — using the operation shown — to produce the target in the cage's top-left corner.
• Operations: + add, − subtract, × multiply, ÷ divide. For − and ÷ the order of numbers doesn't matter.
• A cage with a single cell and no operation is just the given value — write it in.
• Tap a cell, then tap a number on the keypad to place it. Tap ⌫ to clear.
• Turn on Notes to pencil in possible candidates for a cell.
• Tap Check to verify your progress. New generates a fresh puzzle.
• Solve faster for a higher score — your best result is saved on this device.
