I handed five sets of building blocks to my niece and her cousins to find which ones get the most repeat play and survive being tipped off a shelf.

Questions answered

What age is right for building blocks?

Soft foam and large wood blocks start at twelve months. Standard plastic snap blocks like Duplo work from eighteen months and small brick sets are best from age four up because of small parts.

Are off brand blocks compatible with name brand?

Most snap together brands fit the standard stud size and clutch power is close enough for casual building. For precision builds I stick to one brand to avoid frustration.
