Calcura - Calcudoku
Math grid logic puzzles
Free · Designed for iPad. Not verified for macOS.
Sudoku meets arithmetic. Fill the grid so every row and column holds each number once, and every cage hits its target.
Calcura is calcudoku — a number grid where arithmetic does the work.
Fill the grid so each row and each column contains every number exactly once. Then make each outlined cage reach its target using the operation shown: add, subtract, multiply or divide.
