Use our coloured cubes to play and learn

Educational toy for kids older than 3 years old. CE certified for toy safety. 100% made in Greece. Our cubes are easy to connect to each other to build shapes and practise simple arithmetic.
At the same time, they help develop children's fine motor skills, imagination and creativity.


Knossos numbering cubes were created in the early 1970's by Stelios Halkiadakis, famous publisher and bookstore owner in Heraklion, Crete.
Teachers loved the cubes from day one and have been using them consistently in pre-school and first grades to practise simple arithmetic and build shapes.
In 2017 Mr. Halkiadakis' granddaughter, Olia Galenianou, took over the business.

Simple arithmetic

Connect cubes of the same colour in pairs to form even numbers and add or subtract one cube to form odd numbers. For addition you need to connect two numbers and for subtraction you need to remove one from the other.


Fun constructions

Cubes can be connected to each other from all sides creating various geometric shapes and objects such as robots, helicopters, castles, houses, dogs, boats etc. These are just a few examples to get you started. Email us your own ideas !
