KenKen Offline: Math Cages

BlueFuture

About this game

🔢 KenKen / Calcudoku: fill cages with digits so rows, columns, and math targets all work — thirty offline puzzles.

Place 1…N in every row and column without repeats. Each cage shows a target number and an operation (+, −, ×, ÷). Use Notes for candidates, see conflicts highlighted as you play, and climb from 4×4 to 6×6 grids.

🎮 HOW TO PLAY

1️⃣ Fill an N×N grid with 1…N: levels 1–10 are 4×4, 11–20 are 5×5, and 21–30 are 6×6
2️⃣ Every row and every column contains each number from 1 to N exactly once
3️⃣ Bold outlines mark cages; the clue in a cage’s top-left cell is a target and an operation
4️⃣ One-cell cage: just write the number shown
5️⃣ + and ×: the cage’s numbers add up to, or multiply to, the target
6️⃣ − and ÷ appear only in 2-cell cages: larger minus smaller, or larger divided evenly by smaller — which cell holds the larger number doesn’t matter
7️⃣ Numbers may repeat inside a cage, as long as they are not in the same row or column
8️⃣ Cages have at most 2 cells on 4×4, and at most 3 cells on 5×5 and 6×6
9️⃣ Mistakes light up as you play: repeats in a row or column, and full cages that miss their target
🔟 The puzzle is solved when every cell is filled and nothing is highlighted
