The new agreement will see both companies develop side-by-side, with no current plans for a merger.
"BUKA is one of the oldest players on the Russian game market. I always admired the company, its corporate culture, staff, management and operational efficiency," said 1C Company's director Boris Nuraliev.
"The mutual potential of 1C and BUKA opens new unique opportunities and will help us to achieve success on this challenging and rapidly growing market. It will be an honour for us to develop such a well-known and popular brand.”
