Our virtual Gadu-Gadu user, Hot3Bot, sent messages in the form of questions – for example, how many 3Bit bars, on top of each other, would be as high as the Eiffel Tower?Users had to put the phrase “3Bit Hot Number” and the answer in their personal info, and Hot3Bot would send them additional clues to keep them interested.As their friends saw their answers, they became intrigued and participation in the competition spread virally.

Over 81,000 users participated in the contest, and they guessed our number an average 26 times in the space of a week. All of them put the word 3Bit in their personal info box, and that meant that about 500,000 people could see our product name.
