Maths Cage Puzzle — questions

What is a maths cage puzzle?

A number grid where every row and column has each number once (like sudoku) and the squares are grouped into cages. Each cage shows a target and a sign: its numbers must make that target.

Is it free?

Yes — free in the browser on phones, tablets and computers, no download.

Does every grid have only one answer?

Yes. Before a grid is shown, a computer solver tries every possible filling and the cages are drawn again until exactly one filling works.

How should my child start?

Begin with the 3×3 grids. Look for cages with only one way to make the target — two squares making 3+ must be 1 and 2. Then use the rows and columns.

हर पंक्ति और स्तंभ में हर संख्या एक बार आती है। मोटी लाइन वाले हर पिंजरे (cage) की संख्याएँ दिए गए चिह्न से लक्ष्य बनाती हैं — जैसे 7+ का मतलब जोड़ 7।
