Quadratspiele – Caupo is the publishing house of Hans-Georg Krämer – a former teacher who had been working with magic squares for years.

However, he only found the time to put his passion into an educational game when he retired and subsequently published his only game to date, Magic Square Patterns, in 2007.

The game Magic Square Patterns is aimed at both children and adults of all ages and is intended to encourage thinking and puzzling. The only game requirement is that you can add numbers between 1 and 34.

What is also unusual is that on the one hand you can choose the level of difficulty and the associated intellectual demand, but also the game mode, in other words whether you are content to solve the tasks alone or would prefer to compete with others.
