Overview
Calcudo (also known as KenKen) is a logic puzzle played on an NxN grid. Like Sudoku, every row and column must contain the digits 1 through N exactly once. What sets it apart are the cages — coloured groups of cells that each carry an arithmetic target and an operation (addition, subtraction, multiplication, division, or a fixed value). The numbers in each cage must combine under that operation to hit the target.
This project is a fully interactive web app that lets you build any Calcudo puzzle from scratch and solve it instantly, or challenge yourself in Play mode with a hint system to keep you unstuck.
