How does color by number work?

Each space in the picture has a number; the key at the bottom says which colour goes with which number. Colour all the 1s, then the 2s… and the picture appears.

Can it practise maths too?

Yes — choose addition, subtraction or times tables: each space shows a sum, and the answer tells you the colour. Addition and subtraction go up to 10, 20 or 100.

Which level for which age?

Easy has big spaces and five to eight colours, good from about four. Detailed has more, smaller spaces and up to twelve colours for older kids and adults.

Do I need special pens?

Crayons, coloured pencils or felt tips — whatever matches the colours in the key. If a colour is missing, any shade close to it works.
