All the problems are unique and constructed by Bergmandata. We have also constructed a unique IQ game based on IQ test problems.
Earlier we also constructed programs for word processing, spreadsheet and register.They sold 200,000 copies and became very fast the most sold programs in Europe.
As a matter of fact they sold twice as much as all the competitors together. They were marketed by Visma Spcs.
Earlier We worked at Ericsson, IBM, Air Force etc.
