How to play Calcudoku
Controls
Darker borders outline each cage. Its small label gives the target and operation. Select a cell to use the keypad; use Notes for candidates.
The rules
Place 1–5 exactly once in each row and column. Cage values combine to the target with the shown operation. Subtraction and division cages have two cells, read in either order. Digits may repeat in a cage if they are in different rows and columns. Start with single cells and restrictive products.
